Ben Affleck and Will Arnett have joined fellow Batman star Val Kilmer in paying tribute to Adam West, who played the superhero on TV in the 1960s.

Affleck said the late actor, who died last week aged 88, had "exemplified heroism" and remembered him as "kind, funny and an all around great guy".
"Thank you for showing us all how it's done," said the star of last year's Batman v Superman: Dawn of Justice.
"RIP Adam West," wrote Will Arnett on Twitter. "You will always be Batman".
Arnett voiced the Caped Crusader in 2014's The Lego Movie and this year's The Lego Batman Movie.
Kilmer, who played Batman in 1995 film Batman Forever, remembered West on Saturday as "a real gent".
"He was always so kind when we met," said the actor, referring to his predecessor as "dear Adam West".
Kevin Conroy, who voiced the Caped Crusader in Batman: The Animated Series, also paid homage to "the Batman of his childhood".
"He brought us so much entertainment and was a truly class act," he wrote on Twitter.
His sentiments were echoed by fellow voice actor Will Friedle, who voiced the Dark Knight in 2000 animation Batman Beyond: Return of the Joker.
"Thank you Batman for keeping us all safe," he wrote on Twitter.
Others to have paid tribute include Mark Hamill, who voiced The Joker in Batman: The Animated Series.
"#AdamWest was such a wonderful actor & so kind," wrote the Star Wars actor on Twitter.
"I'm so lucky to have worked w/ him & tell him how much he meant to me & millions of fans."
Burt Ward, who played West's Robin in the cult 1960s TV series, remembered him over the weekend as "a great father, a great family man [and] a wonderful human being".
"I'm going to miss him incredibly," he told BBC Radio 5 Live. "It's very difficult to really believe that the end has come."
West died on Friday after a "short but brave battle" with leukaemia, according to a family spokesperson.
Best known for his tongue-in-cheek portrayal of Batman and the superhero's alter ego Bruce Wayne, he also had a recurring role on animated series Family Guy.
In a message posted on the actor's Twitter feed, West's family said they were "so grateful for the outpouring of love from AW's fans, friends, colleagues and the media."
Affleck will again be seen as Batman later this year in Justice League, in which Gal Gadot will also appear as Wonder Woman.

In the mad, gravity-defying career of Britain's new foreign secretary things move so quickly it is hard to keep up.

One day he is the most popular politician in the country, cheered by adoring crowds wherever he goes, on the verge of fulfilling his lifelong dream of becoming prime minister.
A few weeks later he has led an improbably successful campaign to get Britain out of the European Union and is being pursued down the street by angry voters, his career apparently lying in tatters after being knifed in the back by one of his closest allies.
No chance of No 10 now. No chance of redemption either, from a new prime minister who has always seemed to treat him with thinly veiled contempt.
Yet here he is again, a few days later, bouncing up Downing Street in his best suit and tie, to be handed one of the biggest and most important jobs in government.
It has been, to use the old cliche, a rollercoaster. Except, if it were a rollercoaster, Boris Johnson would manage to get stranded at the top of a loop, have to be rescued by paramedics, to ironic cheers from the crowd below, and then somehow turn the whole episode to his advantage.
It is a gift that very few politicians possess. But it does not begin to unravel the riddle that is Alexander Boris de Pfeffel Johnson.
Age: 52
Marital status: Married with four children
Political party: Conservatives
Time as MP: Represented Henley, in Oxfordshire, from 2001 to 2008, and for Uxbridge and South Ruislip, 2015 to present
Previous jobs: London Mayor, Editor of The Spectator magazine; assistant editor, Brussels correspondent of the Daily Telegraph
For readers outside the UK, who might be puzzled by his appointment as foreign secretary, it is best not to think of him as a politician at all, in the conventional sense.
He found fame as a TV personality before he had achieved anything in politics.
His friend, journalist Rod Liddle, once said of his former editor: "Like all politicians, he is sometimes required to talk anodyne or disingenuous rot, but unlike the remainder, he cannot keep a straight face while doing this."
The British public warmed to this quality and it allowed him to get away with the kind of gaffes and indiscretions that would have sunk the career of other politicians many times over.
Pictures of him stranded on a zip wire, waving union jacks, during the 2012 London Olympics, were greeted with mirth, rather than derision.
But it would be wrong to think of Johnson as merely a clown.
A classics scholar, with a more supple mind than the average politician, he is someone with a deep understanding of politics and a fierce commitment to liberal, free-market economics.
As a man of Turkish ancestry, who was born in New York, spent part of his childhood in Brussels and who speaks several European languages, he is one of the most cosmopolitan figures in British politics - far from the Little Englander caricature that clings to some of his Brexit campaign colleagues.
His eight years as London mayor proved he could knuckle down to a serious job.
He was widely assumed to be motivated by a burning desire to be prime minister or, failing that, as he told his family as a boy: "The world king."
In his apparent determination to come across at all times like a minor character in a PG Wodehouse novel, with his tousled hair, rumpled suits and bumbling manner, he would always insist he had as much chance of becoming PM as being "reincarnated as an olive".
But in private, he was said to be a far more serious, and ruthless, figure. He comes from a high-achieving family. His younger sister Rachel is a high-profile journalist and younger brother Jo a government minister, and he had carefully plotted his path to the top.
It was in this context that the other side saw his last-minute decision to campaign for Britain's exit from the European Union.
He had previously been ambivalent about the EU. He had made a name for himself as a journalist in Brussels mercilessly mocking what he saw as petty EU rules and regulations but when it came to whether Britain should leave he sounded unsure.
In 2012, he said: "If we get to this campaign, I would be well up for trying to make the positive case for some of the good things that have come from the single market."
More recently, he had reportedly told friends: "The trouble is, I am not an 'outer'."
In his long career as a newspaper columnist and politician, Boris Johnson has managed to offend a wide variety of people and nations. Here is a selection.
On Tony Blair visiting Africa, in 2002: "It is said that the Queen has come to love the Commonwealth, partly because it supplies her with regular cheering crowds of flag-waving piccaninnies." He apologised for the use of the word "picanninnies" in 2008, during his successful campaign to be mayor of London.
In 2006, he said he would be happy to "add Papua New Guinea to my global itinerary of apology", after writing in a column that "for 10 years we in the Tory Party have become used to Papua New Guinea-style orgies of cannibalism and chief-killing".
The country's High Commissioner in London described the remarks as "an insult to the integrity and intelligence of all Papua New Guineans".  Mr Johnson said: "I meant no insult to the people of Papua New Guinea who I'm sure lead lives of blameless bourgeois domesticity in common with the rest of us." adding that his remarks were "inspired by a Time Life book" which he claimed contained recent pictures of "Papua New Guinean tribes engaged in warfare, and I'm fairly certain that cannibalism was involved".
The following year he had this to say about Hillary Clinton, in a column praising her credentials as a future US president: "She's got dyed blonde hair and pouty lips, and a steely blue stare, like a sadistic nurse in a mental hospital".
During the EU referendum campaign, he got into a public spat with US president Barack Obama after a dig at his "part-Kenyan" ancestry.
He recently won a Â£1,000 prize for composing a rude poem about Turkish President Recep Tayyip Erdogan. We can't print the poem in full, you can read it here - suffice to say, it includes a creative rhyme for "Ankara".
Anyone coming up against the former London mayor on a sports pitch would be well advised to keep out of the way - he famously flattened a 10-year-old boy during a game of touch rugby on a trade visit to Japan.
Boris Johnson: A history of undiplomacy
Boris Johnson's new job: The world reacts
Mr Johnson's decision to lend his star power - and unrivalled ability to reach voters in all parts of the political spectrum - to the Brexit campaign was seen by those running it as a game-changing moment.
He became the face of Brexit in television debates and on the road in his bright red battle bus, a familiar, reassuring face who helped convince voters that quitting the EU was not as big a gamble as his old school friend David Cameron was claiming.
His ability to make Conservative free-market ideology sound liberating and even fun, rather than a dry exercise in accounting, was in full force, as he swept aside warnings about the likely impacts of Brexit as the products of a self-interested elite.
But when the result went his way he seemed a little shell-shocked. His post-referendum news conference was notable for its absence of Johnsonian joie de vivre.
He spent the Saturday after the referendum playing cricket at the ancestral home of Princess Diana's brother, Earl Spencer. There was speculation that he was not focusing on the tasks ahead.
There was also speculation that he had not really wanted Britain to quit the EU at all, just to put up a good fight and be hailed as a gallant loser by Brexit-hungry Conservative Party members who would then vote for him in their droves when the time came to elect a new leader.
For the first time in his life, he had become a hate figure for many people. The man who was used to cycling around London to cheery waves and thumbs-up signs from taxi drivers, was now being barracked by angry voters accusing him of wrecking the country for his own vanity.
Whether this influenced his decision to pull out of the leadership contest - triggered by David Cameron's decision to stand down - is debatable.
His old friend and fellow Brexiteer Michael Gove's dramatic, last-minute decision to enter the race - declaring that he did not think Mr Johnson was up to the job - sealed his fate. It was a brutal political assassination, which was met with dismay by Mr Johnson's supporters.
Not for the first time in his life, he was contemplating the end of his political career.
"Try as I might I could not look at an overhead projection of a growth-profit matrix and stay conscious," on his week-long career in management consultancy.
"Voting Tory will cause your wife to have bigger breasts and increase your chances of owning a BMW M3," on the campaign trail in 2004.
"If I was in charge I would get rid of Jamie Oliver and tell people to eat what they like," striking a blow for the right to eat pies at the 2006 Tory conference. He later described Oliver as a "national saint"
"I think if I made a huge effort always to have a snappy, inspiring soundbite on my lips, I think the sheer mental strain of that would be such that I would explode," - on his unique political style
"I think I was once given cocaine but I sneezed and so it did not go up my nose. In fact, I may have been doing icing sugar," after being questioned on TV panel show Have I Got News for You about drug use
"I have not had an affair with Petronella. It is complete balderdash. It is an inverted pyramid of piffle," on press reports of his relationship with journalist Petronella Wyatt. He would later be sacked from the Tory front bench for these comments
Alexander Boris de Pfeffel Johnson (he is still known to family members as Al) was born in New York to English parents in 1964 and was, until recently, an American citizen.
He had an idyllic childhood spent, in part, on the family farm on Exmoor and in north London, where he attended the same infant school, in affluent Primrose Hill, as future Labour leader Ed Miliband.
In the early 1970s his father, Stanley, moved the family to Brussels after landing a job at the European Commission, in charge of pollution control.
Boris attended the European School in the Belgian capital, where he befriended his future wife Marina Wheeler, daughter of BBC journalist Charles Wheeler.
But in 1973, with his parents' marriage falling apart, he headed off to boarding school in England.
He shone at Ashdown House Preparatory School in East Sussex, developing a lifelong passion for Classics and winning a scholarship to the UK's best-known public school, Eton, where he quickly made an impression.
His headmaster at the school which Prince William and Prince Harry were later to attend, Sir Eric Anderson, was also Tony Blair's housemaster during his schooldays at Fettes - often dubbed the Scottish Eton.
In 1983, Mr Johnson arrived at Balliol College in Oxford to study Classics.
He was already known for his sense of humour and his bumbling "old duffer" persona - but he also displayed a ruthless streak in his pursuit of his political ambitions.
He even briefly spurned his Conservative allegiances in favour of the then fashionable SDP as part of his successful campaign to be president of the Oxford Union.
He was also elected to the elite Bullingdon Club, famed for its hard-drinking, riotous behaviour.
Fellow members included his close friend Charles Spencer and the future Prime Minister David Cameron.
In one group photograph - which would later come back to haunt him - Mr Johnson is pictured lounging decadently in his Â£1,200 Bullingdon Club tailcoat, alongside Mr Cameron.
Halfway through his first year, he met and fell in love with Allegra Mostyn-Owen, a fellow student who also modelled for society magazine Tatler in her spare time.
In 1987 - when they were both 23 - he married Allegra in a grand ceremony at a Shropshire stately home, complete with an opera singer and a string quartet.
According to biographer Andrew Gimson's account, Mr Johnson managed to turn up in the wrong clothes - walking down the aisle in trousers belonging to Tory MP John Biffen - and lost his wedding ring within an hour of receiving it.
The marriage lasted less than three years, by which time Mr Johnson was beginning to make a name for himself as a journalist in Brussels.
His first attempt at forging a career, as a trainee management consultant, lasted a week.
His career in journalism very nearly fell at the first hurdle too, after he was sacked by the Times for making up a quote.
He had been trying to spice up a dull story about an archaeological dig but the editor - and the history don he "quoted", who also happened to be his godfather - failed to see the funny side.
He described the episode in an interview with the Independent in 2002 as his "biggest cock-up".
Luckily for him, the then Daily Telegraph editor, Sir Max Hastings, was prepared to overlook this indiscretion.
He took on Mr Johnson as a leader writer and then the newspaper's Brussels correspondent.
Mr Johnson took to his new role with relish, merrily debunking the stuffy European institutions his father had served as a commissioner and Tory MEP.
But disaster loomed again, when a tape surfaced of an old Oxford friend, Darius Guppy, who had been convicted of fraud, asking him to help locate a witness.
"He did not say yes, but neither did he say no," recalled Sir Max, who interrogated him about the tape which had been sent to the Telegraph anonymously.
"He evoked all of his self-parodying skills as a waffler. Words stumbled forth... never intended... old friend... took no action... misunderstanding," added Sir Max in the Observer.
He said he was satisfied Johnson had not been guilty of any impropriety and "dispatched him back to Brussels with a rebuke".
He was, by now, married to Marina Wheeler, his childhood friend from Brussels, who had become a successful barrister.
The two had never quite lost touch and after his divorce from Allegra, he set about pursuing her with characteristic persistence.
Their first child, Lara Lettice, was born in 1993, with three more children - Milo Arthur, Cassia Peaches and Theodore Apollo - following in quick succession.
He had stood unsuccessfully for the Conservatives at the 1997 general election, in the Labour stronghold of Clwyd South.
Two years later, when he was made editor of The Spectator, he told its proprietor at the time, Conrad [now Lord] Black, he would give up politics to concentrate full-time on the magazine.
But he continued to agonise over his decision in private, confessing to friend Charles Moore: "I want to have my cake and eat it."
In 2001 he stood for Michael Heseltine's old seat, Henley in Oxfordshire, and won.
But with The Spectator continuing to publish articles which proved embarrassing or irritating to some of his new parliamentary colleagues it was, perhaps, only a matter of time before Mr Johnson came unstuck.
It was an unsigned Spectator editorial, accusing the citizens of Liverpool of wallowing in their "victim status" over the murdered Iraq hostage Ken Bigley, that finally did it.
The Tory leader at the time, Michael Howard, resisted calls to sack Mr Johnson. He had what turned out to be a far worse fate in mind - and dispatched his errant culture spokesman to Liverpool to apologise to the entire city.
The mission quickly descended into farce, however, as he was pursued by a media pack hungry for more gaffes. One reporter described it as an "Ealing comedy".
On a radio phone-in he was given a humiliating dressing-down by Paul Bigley, brother of Ken, who told him: "You're a self-centred, pompous twit - even your body language on TV is wrong."
He endured the ordeal, which he later dubbed Operation Scouse Grovel, with good grace.
But he was sacked by Mr Howard a few weeks later in any case, for allegedly lying over an affair with journalist Petronella Wyatt - something he vehemently denied.
When challenged about the relationship by the Mail on Sunday, Mr Johnson denied everything, calling stories about it an "inverted pyramid of piffle".
He suffered the indignity of being thrown out of the family home - and was hounded by the tabloid press as he went for a run wearing a skull-and-crossbones bandana.
Mr Johnson was seen as good copy, always ready with an amusing quip or a fresh piece of buffoonery, but any hopes of climbing higher up the political ladder seemed to be over.
The man who had dreamed of being in the Cabinet by the age of 35 watched as Mr Cameron, an Eton and Oxford contemporary two years younger than him, grabbed the Tory leadership.
Mr Cameron handed his old friend the junior role of higher education spokesman on the condition that he gave up editing the Spectator, which had seen its circulation soar under his guidance.
There was a new sense of seriousness about the way Mr Johnson tackled the higher education brief and it was a springboard to the job that would define his political career to this point - London mayor.
Mr Cameron had been determined to draft in someone from outside the party, preferably a well-known celebrity, to take on Labour incumbent Ken Livingstone as part of his efforts to broaden the Conservatives' appeal.
But when those efforts came to nothing, he turned to the party's own in-house celebrity.
He got down to the job of proving he was a serious candidate, displaying hitherto unseen levels of discipline, storming to victory over Mr Livingstone and gaining a huge personal mandate of more than a million votes.
As mayor, he championed liberal social policies, such as a living wage, and put his stamp on the capital by banning "bendy buses" and introducing a cycle hire scheme, which inevitably became known as the "Boris bikes".
He was a vehement opponent of a third runway at Heathrow airport, arguing instead for the construction of a new airport on reclaimed land in the Thames Estuary, a stillborn scheme that inevitably became known as "Boris island".
He was criticised for a lack of focus on detail and of failing to get to grips with some of the capital's long-term problems, such as a shortage of affordable housing, and for being slow to respond to the riots that swept the city in the summer of 2011.
But he proved to be a first class advocate for London as a vibrant, multicultural economic powerhouse. He toured the world banging the drum for London business and managing, most of the time, to avoid putting his foot in his mouth.
He was rewarded with a second election victory over Mr Livingstone in 2012, cementing his status as the most popular Conservative politician in the country.
Within weeks, he had the perfect stage on which to bask in his popularity in the London Olympics. He returned to the House of Commons at the 2015 election in the safe Conservative seat of Uxbridge and South Ruislip and - until his Brexit hiccup - looked on course to succeed David Cameron as prime minister.
His latest political comeback sees him getting a full cabinet seat for the first time - he had previously been a member of Mr Cameron's "political cabinet," which did not take policy decisions - and in one of the traditional "great offices of state".
Colleagues have argued that his new-found status as a "Europhile Brexiteer" may be what is needed, as he attempts to reassure the world that Britain is still an outward-looking nation.
Some wonder whether his gift for blunders will be his undoing, and that foreign dignitaries he meets in his new role will be left bemused, rather than charmed, by his very English brand of eccentricity.
On his first day in the job he described his mission as "reshaping Britain's global identity as a great global player" and stressed that just because the government would "respect the will of the people" and take Britain out of the EU it did not mean the country would be leaving Europe.
He brushed off questions about his past gaffes and insults, and negative comments about his appointment, saying it was "inevitable that there would be a certain amount of plaster coming off the ceilings in the Chancelleries of Europe" after Britain's Brexit vote, and they were "making their views known in a free and frank way".
Something he, of all people, would know plenty about.

Got one? Good. Congratulations. Chances are that by plucking that number out of the ether you have done a better job than Google of predicting the percentage increase in the number of flu-like illnesses that will strike Americans over the next few weeks.
That's right. You, armed only with your puny brain, can outdo a multi-billion dollar corporation that employs some of the smartest people in the world.
This example might seem trivial, but many think it matters because of the status of Google Flu Trends (GFT), once seen as the shining example of the power of so-called big data.
The data it uses to make predictions about how many will be sneezing and wheezing a week or so ahead is drawn from search terms, blog entries and messages shared via social media - so-called unstructured data.
This is very different to the structured and slow stream of information gathered from forms filled in at surgeries and hospitals that, before the rise of big data, were how predictions were made.
And the problem is, GFT turned out not to be terribly accurate.
In a run of 108 weeks, GFT wrongly predicted the number of flu cases 100 times, revealed a recent study.
Sometimes its estimate was double the number of actual flu cases recorded by US doctors. Hence the reason anyone can do better by plucking a number out of thin air.
Yet this unstructured data humans put online is exactly the type of stuff that companies want to analyse when they kick off their own big data projects.
Many corporations are keen to use those garbled knots of human sentiment to monitor how their brands are faring online, and to tweak their operations accordingly when they spot commercial opportunities or potential PR disasters.
Before now, those giant data sets had been hard to unpick. GFT seemed to suggest that with the right tools it could unlock all kinds of useful predictions.
Not only that, but those predictions could be uncovered quickly and cheaply.
Why did GFT go so wrong and what implications does this have for other big data projects?
"There's no such thing as clean and stable data," said statistician Kaiser Fung who has written extensively about the pitfalls that can dog big data projects.
What he means by "clean and stable" is that it is a mistake to think that the data Google gathered for GFT today is the same as it gathered last week, last month or last year.
Google regularly tweaks the algorithms it uses to index online life and, as a result, may be sampling very different things month to month, adding a degree of instability - spots of dirt as it were - to that dataset.
The same is true of any big data set gathered by anyone, he said.
All will be tainted in some way as they will miss out something simply because of the quirks of the underlying code used to parse and index web pages, social media messages and blog posts.
That will be particularly true if companies buy in their data from different sources and then treat it as all one corpus.
"I have never come across a complete data set," he said. "Often times the only reason why people believe their data is clean is because they have never looked at it."
Companies in possession of a huge corpus of data can assume that all the information they need is in it. Sadly, he said, this "N=all" assumption is wrong.
"It is much better to assume that the data has holes and flaws than it is to assume it is complete."
Any company starting a big data project would do better to look at the data they have gathered and clean it up before any analysis starts.
There are other good reasons for scrutinising that mass of information about customers, says Patrick James, a partner in consultancy Ernst and Young's consumer practice.
"There's a customer backlash about to happen," he says. "It's against the big part of big data."
More and more people are getting less and less happy about simply surrendering information and getting nothing in return, he maintains.
Increasingly, consumers and customers will attempt to hold back their data, limit what they share online or simply give the wrong answers when they sign up for a service or are quizzed about their life and habits, he believes.
The tens of thousands of people who filled in a form to make Google expunge their data from its index was evidence of that growing desire to disappear, says Mr James.
If this trend grows, it could mean data sets get skewed and become less useful for those big projects.
These early days of big data might prove to be its golden age.
"Data has never been cheaper than it has been today and it's only going to get more expensive," says Mr James.
So, if data is not the key to a good project, what is?
"Too many big data projects are started by the IT departments in companies that want to play with new technologies like Hadoop," says Dr Laurie Miles, head of analytics at big data specialist, SAS.
"That's led to scepticism, because in the history of IT projects a lot of them have been failures."
Instead of the technology coming first, anyone embarking on a big data project needs to know why they are doing it before they sign off on any expenditure by the IT folks, he argues.
"A big data project is not going to deliver any benefit unless you focus on a specific problem."
That focus can stop a project running away with itself and ensure it produces results that impinge on a real business issue, he says.
Spotting fraudulent credit card use requires a very different approach to analysing the performance of elite rowers - SAS is helping with both.
"We analyse credit card data at the point of sale, and you need that quickly," says Dr Miles. "With British Rowing we have a couple of weeks to to give them answers."
Knowing the response can help define the technology needed to underpin that big data project.
"Often you do not need to spin up a massive IT infrastructure to make this work," he says. "That's just as well, as real time results are really expensive."


Olympic 1500m silver medallist Gamze Bulut has been provisionally suspended pending an IAAF investigation into a possible doping violation.

Turkey's NTV television reports that abnormalities were found in Bulut's blood samples from 2011, 2012 and 2013.
The 23-year-old is the fifth 2012 Olympic finalist to face drug allegations, along with fellow Turk Asli Cakir Alptekin.
Alptekin has since been stripped of her gold medal and banned for eight years.
Nataliya Kareiva of Belarus and Russian athlete Yekaterina Kostetskaya, who finished seventh and ninth respectively, have since been banned by the International Association of Athletics Federations (IAAF) for biological passport abnormalities.
Ethiopia-born Swede Abeba Aregawi, who finished fifth in London, was suspended last week pending an investigation after testing positive for a banned substance.


Hundreds of jobs could be lost if Rolls-Royce moves it research and development work out of Derby, a Unite union organiser has said.

Tony Tinley responded to The Sunday Times report that the company may spend research budgets overseas if government support for innovation is cut.
Mr Tinley said he wanted the firm to commit itself to the city.
Rolls-Royce said it invests in research and development "where the environment is supportive".
The union fears that grants offered by the department for Business, Innovation and Skills, to firms like Rolls-Royce, could be turned into loans as a result of spending cuts.
Mr Tinley, a senior regional Unite officer in the East Midlands, said: "If you move [research and development], the manufacturing goes with it.
"You could be arguing that the whole presence of Rolls-Royce is being put at risk.
"I get called a scaremonger for this but when I've sat and looked in the eyes of these people [senior management], I don't see that commitment."
Dr Ian Jackson, from Staffordshire University's business school, said turning grants into loans could have a serious effect on Rolls-Royce.
He said: "It would put at risk the qualified scientists and engineers not just at Rolls-Royce in Derby, but also the supply chain, and wider into the hinterland of what supports that."
Rolls-Royce, which employs about 13,000 people in Derby, said in a statement: "Rolls-Royce has always maintained that we invest in research and development where the environment is supportive.
"The location of research and technology is dependent on where the early stages of innovation happens, and the UK today has a compelling and competitive environment for Rolls-Royce to invest."
A government spokesperson said: "We want the UK to be the best place in Europe to innovate and grow a business.
"We are simplifying support for business, boosting collaboration and investing in research infrastructure on a record scale."


A Thai court has dismissed a criminal defamation case against a British labour activist who criticised conditions in the food industry.

A Thai pineapple company brought the case against Andy Hall after a report he wrote which alleged labour abuses by the firm and others.
The court said the investigation into the case did not meet certain legal requirements.
Mr Hall faces more charges of violating Thailand's computer crimes act.
Last year, Mr Hall authored a report for Finnwatch, a Finland-based watchdog, alleging poor labour conditions in seafood and pineapple export companies in Thailand.
The allegations include wages below the legal minimum, long working hours at factories and illegally confiscating passports.
Natural Fruit, which brought the charges, was one of the companies named and denies the findings of the report.
The defamation charges relate to an interview Mr Hall gave to the Al-Jazeera network on the allegations in the report while in Myanmar (formerly known as Burma).
"Hall gave the interview outside of the Kingdom of Thailand therefore the investigation into the case had to include a team of police and officials from the attorney-general's office," a judge said.
"However, there was only one police officer at the time of his interrogation, therefore we deem the investigation to be incomplete."
On Finnwatch's Facebook page Mr Hall said: "I'm delighted at today's court ruling. It's real victory for migrant workers, labour rights, rule of law, freedom of expression in Thailand".
A lawyer for Natural Fruit said the company would appeal against the decision. Mr Hall also still faces a number of other civil and criminal defamation cases brought by the firm.
He has also been charged with violation of the computer crimes act, which holds a maximum sentence of seven years in prison.
The BBC's Jonathan Head in Bangkok says Thailand's treatment of migrant workers has come under ever increasing international scrutiny.
Thailand imports migrant labour from neighbouring countries such as Malaysia, Cambodia and Myanmar for farming, fishing and construction jobs.
However, many work without official permits and are paid below minimum wage.


Formartine United midfielder Derek Young hopes Scottish Cup opponents Partick Thistle come back "tanned and tired" from their winter break.

The Jags spent time in La Manga ahead of Saturday's fourth-round tie versus the Highland League club at Firhill.
"We're not daft, we're playing a Premiership team who were doing really well just before the winter break," said the former Thistle player.
"Hopefully we'll catch them a wee bit rusty," added the 36-year-old.
Thistle took seven points from their last three matches to move up to seventh in the league.
Formartine United, based north of Aberdeen in Pitmedden, have already shocked League Two Annan Athletic in the competition, beating them 4-0 in the third round.
Young made more than 200 appearances during two spells with Aberdeen and also had stints at Dunfermline, Queen of the South, Morton, Forfar and Grindavik in Iceland.
He came on as a late substitute when the Dons lost 4-3 in a Scottish Cup semi-final to Queen of the South in 2008.
"I've been the other way about when we were the team playing the lower side side," said Young.
"You need to have your wits about you and our boys are desperate for the day to arrive, it can't come quick enough.
"[Current manager] Alan Archibald was there [as a player] when I played for Partick Thistle and I see him every so often at coaching conventions and we chat away. He's done a fantastic job there."
Young played in Aberdeen's European ties against Atletico Madrid, Hertha Berlin and Dnipro and admits adjusting to performing in rural corners of the north of Scotland has been slightly strange at times.
"We were laughing the other day because we had a four-hour bus journey up to Fort William and behind one of the goals was a mountain," added Young.
"Someone asked me what I thought of it and I said, 'it's not the Vicente Calderon but it'll need to do'.

Former TV-am host Nick Owen has claimed viewers are put off watching ITV's breakfast shows because of the high salaries paid to big-name presenters.

It comes as former BBC Breakfast host Susanna Reid prepares to front new show Good Morning Britain from next week, in a deal reported to be worth Â£1 million.
It replaces Daybreak, whose highly-paid launch presenters Adrian Chiles and Christine Bleakley lasted one year.
Owen said press speculation about big salaries can "alienate viewers".
"Here's someone on a million pounds - you will enjoy them! Who can relate to a presenter like that?" he added.
Owen has extensive experience with breakfast TV, having started at TV-am's Good Morning Britain show in 1983 as a sports reporter before going on to become a main presenter with Anne Diamond until 1986.
They helped to turn around the show's fortunes and it went on to be very successful.
Owen rejoined Diamond on the sofa in 1992 to co-present Good Morning with Anne and Nick on BBC One until 1996, and he now presents for the BBC's Midlands Today programme.
"I joined TV-am after a raft of big names had failed - David Frost, Michael Parkinson, Anna Ford, Angela Rippon... they'd not caught on with the viewers at all," Owen told the Radio Times.
"They'd been turned down by Terry Wogan and Michael Aspel, so I was filling in until they could find someone, basically.
"But because no-one was watching, we could try things out."
Reid has said she quit the BBC last month after "a fabulous two decades" as the new ITV job was a "fantastic opportunity".
"At the age of 43, I have got three children and I have been a journalist for more than 20 years - and so I do hope I know a few things about quite a lot of stuff," Reid said.
"It's not often in your career you get the opportunity to build something new that is really exciting and so engaging.
"I do like to challenge myself and do things that are different. It's good to push yourself."
Since Daybreak replaced GMTV in 2010, ITV has continued to struggle to compete with BBC Breakfast's viewing figures.
On Thursday 17 April, an average of 489,300 tuned in to Daybreak while an average 1.38 million watched Breakfast on BBC One.
ITV has not commented on how much Reid will be paid when she joins Ben Shephard, Charlotte Hawkins and Sean Fletcher on Good Morning Britain.
The presenter has said she is less nervous about fronting the new show than she was about appearing on Strictly Come Dancing last year.
"I don't dread anything. Even the early morning alarm clock," she told the Radio Times.
"When you have done Strictly Come Dancing live on a Saturday night in front of millions... I'll never be that nervous again."
Daybreak has gone through both line-up changes and four different editors since its inception in 2010.
Lorraine Kelly and Aled Jones became Daybreak's presenters in September 2012, taking over from former GMTV presenter Kate Garraway and Dan Lobb.
The pair had been filling in since Adrian Chiles and Christine Bleakley left the programme in November 2011, 14 months after Daybreak's highly publicised launch.
ITV's head of daytime programmes Helen Warner said Good Morning Britain's number one priority would be "engaging, news-driven content".

David Haye has rarely been one to conform.

Before commentating on his first world-title success in November 2007, I remember wandering into the lobby of the hotel in Paris where we were both staying to see Haye lounging around, talking to friends.
It was late Saturday afternoon and the biggest occasion of his career at that stage - against the Frenchman Jean-Marc Mormeck - was just hours away.
Frank (now Kellie) Maloney, his then promoter, was concerned about Haye's attitude. "I wish he would just go to his room and relax," Frank said to me.
Rest and solitude might have been prescribed for most boxers but Haye never read the copybook.
In beating Mormeck, a man who had lost only once in the previous decade, Haye produced one of the greatest wins by a British boxer in a foreign ring.
Two years later, he gave away seven stone in weight and made the Russian beanstalk Nikolai Valuev chase shadows in Nuremberg to add a version of the world heavyweight crown to his cruiserweight glories.
Previously, only Evander Holyfield had won world titles in both divisions. And Haye won each of his away from home.
Back then, his ability to revile took root. His comments at news conferences and other promotional events were as disgusting as his ringside analysis was erudite. Social media platforms were unborn or in their infancy but still he got his vulgarity across.
Judging by his attitude in the build-up to the Tony Bellew fight this weekend, the persona endures. But in attempting to rattle Bellew, Haye himself has lost at least a semblance of control.
He complained after Monday's news conference in Liverpool about some of the abuse he was subjected to by the hundreds of Bellew fans in attendance.  Having promised to "cave someone's skull in", there was little room for objection when the fire was returned.

A sub-plot on Saturday is the daunting challenge facing the trainers, both of whom are coming off defeat in a world title fight. Shane McGuigan was in the corner when Carl Frampton was beaten by Leo Santa Cruz in their rematch in January. Dave Coldwell has suffered reverses with Gavin McDonnell and heavyweight David Price in a three-week spell.
The careers of McGuigan and Coldwell will continue after Haye and Bellew have departed the scene but the result on Saturday will help shape how they are regarded.
Part of the trainers' role will be to moderate emotions and limit the red-mist tendencies. But whatever the guidance from the corner, the most important factor relates to how much of Haye the fighter, the calculated practitioner who beat Mormeck and Valuev, remains.
In almost five years, Haye has been involved in only two fights, against non-league opposition, lasting a total of less than seven minutes. In the same period, Bellew's log shows 13 fights and 113 rounds.
For all that, the fight has the feel of last year's showdown in Las Vegas between Amir Khan and the Mexican Saul 'Canelo' Alvarez, when Khan was knocked out savagely in the sixth round.
We tried to make a case for the underdog but the evidence against him was overwhelming. And Bellew is quoted at even longer odds than Khan was back then.
McGuigan has indicated that Haye might weigh in lighter than Bellew, suggesting an attempt to rekindle the blazes of old. The adage tells us that the last asset a fighter loses is the power of his punch. Perhaps… but he does lose the ability to land it.
Even so, Haye only has to get it right once. Bellew must get it right all night.
Momentum is building around a showdown between Khan and WBO world welterweight champion Manny Pacquiao. Khan was BBC Radio 5 live's big fight summariser alongside me in Vegas recently when Frampton was outpointed by Santa Cruz.
That night, Khan was adamant that his next fight would be a relatively low-key affair because he wanted to test the right hand on which he had surgery after the Alvarez defeat last May.
But the money and the prestige of a showdown against Pacquiao make an offer difficult to refuse. I watched them train together in making a documentary about Pacquiao for BBC World Service in 2010.  At the time, the Filipino was preparing for a light-middleweight title fight against  Mexican Antonio Margarito and Khan was among the sparring partners.
Pacquiao beat Margarito emphatically and Khan went on to outpoint Argentina's Marcos Maidana in Vegas shortly afterwards for one of the most impressive victories of his career.
More recently, Pacquiao has recovered from his defeat against Floyd Mayweather almost two years ago to beat Americans Timothy Bradley and Jessie Vargas. At 38, he might well be fading but Pacquiao is still better than most. And those performances since May 2015 serve to endorse the greatness of Mayweather.
The critics continue to carp about Mayweather's credentials and a record supposedly padded with carefully-chosen fall-guys. Yet consider what Puerto Rico's Miguel Cotto, Mexican Juan Manuel Marquez and Pacquiao have gone on to achieve after losing to him and the arguments descend into nonsense.
We launched a new "5 Live Boxing" podcast this week, with me and long-time ally Steve Bunce in union. It is 42 years this week since we first appeared together on a junior club show in Streatham, south-east London, at a boxing hotbed called The Cat's Whiskers.
We both lost but a lifelong passion was being battered into us. Also on the bill was Sammy Reeson, who 10 years later became the first holder of the British title in the new cruiserweight division.
Among my future opponents was Jim McDonnell, who later took the legendary Ghanaian Azumah Nelson into the 12th round of a world title fight and now trains the British world super-middleweight champion James DeGale. Jim beat me on points and never granted me a rematch. Strangely, I never complained.


An exhibition of 40 photographs of David Bowie, some previously unseen, is to begin a nationwide tour in July.

Norwich is the first stop for David & I, which features pictures taken by rock photographer Denis O'Regan.
O'Regan was official tour photographer when most of the photos were taken between 1978 and 1990.
Exhibition organisers said that as well as live shots, many images featured the late singer out and about in countries he was touring.
O'Regan said: "It represented me being on tour, and also doing stuff on the tour that had nothing to do with the tour.
"David had never been photographed in this way before... this was the first time anyone had really been given that access.
"If you're there all the time, you get a lot more coverage."
The touring exhibition was arranged by Mark Overton, who runs a gallery at Carleton Forehoe near Norwich.
He said about half the O'Regan photos will be fresh for the public and they were mainly taken on the Serious Moonlight, Glass Spider and Sound & Vision tours between 1983 and 1990.
Mr Overton said: "Denis and David were good friends, so it's a tribute to Denis he was allowed to take so many photographs in so many different circumstances.
"Having reviewed an awful lot of photographers, Denis's work with David Bowie, the Rolling Stones, Duran Duran and Thin Lizzy is tremendous and I'm not sure there are too many photographers with that range in their portfolio - so he's very important, spans a very long time and he is still working."
The one-day exhibition starts at the Mini dealership at Forest Way in Norwich on 28 July and then visits other showrooms in Brighton, Chelmsford, Birmingham, York, Cambourne in Cambridgeshire, Edinburgh and Glasgow between August and November.


Police have made two arrests over an armed robbery at a shop in Armoy, County Antrim.

Two robbers, believed to have been armed with a gun and a knife, entered a shop on Coolkeeran Road at about 19:00 GMT and demanded money.
They stole cash and cigarettes. No-one was injured in the robbery.
Later on Saturday evening, police arrested a 22-year-old man and a 16-year-old boy.  They were detained in north Belfast and are being questioned.


Whether you want to look your best in your holiday snaps without hitting the gym, or boost your World of Warcraft credentials without putting in the hours, there are experts out there whose job it is to make you shine online.

The chances are you will never meet them face to face, but there is an entire industry dedicated to helping individuals and businesses manage their online reputations in their chosen areas of the net - for a price.
With more than 10 million players worldwide, some of whom play for 12 hours a day or longer, it can be difficult to keep up in the many realms of Blizzard Activision's World of Warcraft game.
While it is completely against the terms and conditions of play, some gamers turn to the services of so called "arena boosters" - professional players who will play on their behalf until their character is in the higher levels of the game.
Former arena booster Philipp Karbun told the BBC that, as a teenager and one of the game's top-rated players, he started getting messages from others within the game asking for his help - and his contacts were often from wealthy countries like Saudi Arabia.
"In the beginning I just wanted to help people," he said.

"I was a computer programmer... but I soon realised how much money could be made."
Now aged 25, Philipp Karbun no longer works for the company he founded. The services he offered ranged from 150-490 euros (£130-£420), and he employed 10 fellow full-time gamers to share the work.
Mr Karbun, from Austria, claims despite efforts by Blizzard to crack down on this activity by checking the IP addresses of players - and throwing them out of the game if they are discovered - the business is booming, with arena boosters using proxies and VPNs to avoid detection, or even migrating the account of their clients completely until their service is completed.
"Some of the customers, their friends found out, they got boosted and it affected their reputation," said Mr Karbun.
"But that's the buyer's problem."
Mr Karbun no longer plays World of Warcraft, and now makes money from video streaming his legitimate gaming activities.
"I calculated I spent 20,000 hours on the game - eventually I lost interest," he said.
"I'm happy that I've found another way to make money."
Dane Cobain is a social media specialist at marketing agency FST Group. He runs the social media activities of up to half a dozen clients at a time - but has a record of 15.
Mr Cobain's clients tend to be businesses, but individuals have included a hip hop artist, and, perhaps ironically, a communications coach.
"Individuals are still brands," he said.
"Tone is especially important for them - do you want to use smileys? How serious or playful do you want to be? B2B tends to be more formal."
Mr Cobain's agency offers a range of services, from initial strategic advice to taking over the entire feed. The cost depends on how much support is required, he explained, but the results are often tangible.
"It can be quite hard to prove the ROI [return on investment] of marketing but there are certain things you can do with social media.
"You can prove the numbers of people who came through Facebook for example - you can tie that back to revenue," he said.
Why don't people just do it themselves?
"A big challenge for clients is keeping up to date with all the new things that are coming out," said Mr Cobain.
"A lot of people are still trying to wrap their heads around Twitter and Facebook- then you've got Instagram and Pinterest and even Snapchat is getting big now."
Record-breaking yachtsman Sir Robin Knox-Johnston is very candid about his decision not to engage personally with Twitter, despite having an account in his own name which was launched at the beginning of the year.
He has around 700 followers and has so far posted 136 tweets.
"I had to be persuaded that Twitter was necessary, and I have no interest in having a Twitter account," he told the BBC.
"However the team at work said I should have one, so I agreed, but on the understanding I did not have to do anything to make it work."
Sir Robin, who was the first sailor to circumnavigate the globe single-handedly and without stopping, is chairman of the Clipper Ventures boat empire.
He says he does write his own tweets, which he then passes on to his office.
"I don't feel I am missing anything when I see how mundane most tweets are," he added.
James Bradley launched his budget image improvement and restoration service Repixl earlier this year.
He charges under £10 for individual photo restoration and offers a range of low-cost airbrushing services for a couple of pounds.
"People are still on their holidays but airbrushing and editing work is starting to come through," he said.
"They might just be after dinner snaps - but they are also a once-in-a-lifetime memory."
Mr Bradley added that some people find photo editing tools too challenging to use.
"Even the more simple tools are relatively complicated," he said.
"It's all about the human touch - you need someone who understands the picture."
Mr Bradley told the BBC that while he doesn't keep records of his clients' ages, he believes they lean towards the older demographic - but the service is also proving popular with estate agents.
"Lots of them use their phones to take pictures," he said.
"The cameras are amazing but the lens size and the weather still cause problems. They use us to straighten pictures, remove litter from the ground, put a blue sky in the background.
"It's not against the Trades Description Act."


A 16-year-old boy is in a critical condition in hospital after he and another teenager were attacked by knifemen riding mopeds in south London.

The victims were stabbed in the torso in Mountearl Gardens, Streatham, at about 17:30 GMT on Wednesday.
Police suspect four people approached the victims on mopeds and the pillion passengers carried out the attack.
The second boy, a 17-year-old, was treated for his injuries and has been discharged from hospital.
Detectives said neither of the pillion passengers were wearing a helmet and have urged witnesses to contact them with a description of the attackers.
Det Ch Insp Jim Redmond said: "This was a vicious and violent attack which has left a teenage boy in a critical condition.
"The incident happened late in the afternoon and there would have been a number of people in and around the area who may have witnessed the events in the lead up to the attack, the stabbings themselves or the moped riders with their pillion passengers fleeing the scene."
Anyone with information is urged to contact police or call the Crimestoppers charity anonymously.


Martin McGuinness has denied that his three-day visit to the United States for talks about the Stormont budget crisis has been a waste of time.

He said if the crisis was not resolved by September, Stormont's government would be "hanging by a thread".
The Sinn Féin MLA has faced criticism from unionists for meeting US officials instead of holding more talks at home.
But said he would not have been invited to US meetings if White House officials believed the talks were pointless.
During his trip, Northern Ireland's deputy first minister has met representatives from the US State Department and influential Irish Americans, asking them to lobby the British government to give more financial support to Stormont.
His trip has coincided with a diplomatic visit to the US by Northern Ireland Secretary of State Theresa Villiers, who has said a budget increase is not an option.
On Tuesday, Democratic Unionist Party (DUP) Minister, Arlene Foster, described Mr McGuinness' US mission as a "waste of time".
However, he disagreed and said he had "come away very encouraged" by what he had heard from Barack Obama's administration.
"The fact is Theresa Villiers is here as well.  Does Arlene consider that Theresa Villiers' trip is a waste of time?" Mr McGuinness said.
"Certainly the White House [staff] don't think it's a waste of time. I wouldn't have been invited to meet with a key official if that had been the case."
The Sinn Féin MLA said he was "working flat out" to achieve a resolution to the welfare reform crisis that has engulfed Northern Ireland's political institutions for months.
He said he had made the US government aware of the seriousness of the crisis threatening Stormont's future and the likely timescale.
"The institutions, if we don't resolve this problem by September, are effectively hanging by a thread," he told BBC Radio Ulster.
Mr McGuinness said the money required to resolve the welfare budget row was a "drop in the ocean" compared to the resources that British governments had spent "pacifying" Northern Ireland during the Troubles.


Pepper, the robot that has been trained to "perceive" human emotion, is opening up its platform to Android developers.

Maker SoftBank is hoping that it will spur new apps and new capabilities for the humanoid robot which has sold well but still has no clear defined purpose.
Ten thousand of the robots have been sold but developers have been slow to make apps for its closed Naoqi operating system.
Android will run on a tablet strapped to the robot's chest.
Neither Google nor SoftBank has disclosed what sort of business deal they have struck and it is unclear if the robot will take advantage of new features such as the recently announced artificial intelligence Google Assistant.
But it will almost certainly offer Google some degree of control over the robot as well as a cut of revenues.
Pepper has been in big demand in Japan with each batch of 1,000 units selling out in minutes. It will go on pre-sale in the US in July.
It costs 198,000 yen ($1,800) and each one is sold at a loss.
The 1.2m (4ft) humanoid bot features more than 20 motors and has articulated arms. It was designed to understand emotions and mimic human body language - so, for instance, its shoulders go up when it is in standby mode, imitating sleep.
So far, Pepper is being used as a waiter, salesman and customer service representative in around 500 companies in Japan, including Nestle, Mizuho Bank and Nissan.


A BBC team filming tensions on the Turkish-Syrian border has been tear-gassed by Turkish police as it left protests by local and Syrian Kurds.

Police fired two canisters towards the team, one of which smashed into their car, filling it with gas.
The incident occurred near Kobane, the scene of fierce fighting between advancing Islamic State (IS) militants and Syrian Kurds defending the town.
Kurds in Turkey are angry at perceived Turkish inaction in the battle.
Possibly prompted by a rocket, which landed in a house on the Turkish side of the border, the authorities decided to evacuate the whole area.
It was done with a heavy hand, using volleys of tear gas. Kurdish activists scattered across the fields, pursued by white clouds of gas.
We stopped to film a final piece to camera before leaving. Across the field, people were rushing to attend to a body lying prone in the dirt.
A white police truck approached and fired a tear gas canister which bounded along the track beside us.
As we clambered into our vehicle and started to leave, a second canister smashed through the rear window. It had been fired from no more than 10 feet away and could easily have killed anyone it hit.
The van quickly filled with choking tear gas. Curtains and upholstery started to catch fire. As we coughed and spluttered on the ground outside, our quick thinking driver and safety adviser put the fire out.
As we drove into the nearby town of Suruc, angry Kurdish youths were putting rocks across the road and brandishing stones. They were spoiling for a fight.
Meanwhile activists from the Syrian Observatory for Human Rights say a female Kurdish fighter has carried out a suicide attack on IS positions in the east of Kobane, killing a number of jihadists.
US-led forces have been conducting air strikes on IS positions in the area to try to slow their advance.
The strikes appeared to have slowed the IS advance, although the jihadists had captured part of a strategically important hill which would make it easier to take the town itself, the activists added.
The militants have been besieging the town for nearly three weeks. More than 160,000 Syrians, mainly Kurds, have fled across the border since the offensive was launched.
Capturing the town, also known as Ayn al-Arab, would give IS unbroken control of a long stretch of the Syrian-Turkish border.
Turkish Kurds and refugees have clashed with Turkish security forces on the border for the last two days.
They are angry and disappointed at Turkey's perceived inaction over IS in recent months, as well as its refusal to allow them to cross into Syria to fight.
Last week, Turkey pledged to prevent Kobane from falling to the militants and its parliament has authorised military operations against militants in Iraq and Syria.
But it appears to have taken no action so far to prevent the fighting.
Correspondents says Turkey is reluctant to lend support to the Kurdish forces in the town because they are allied to the PKK, banned as a terrorist organisation in Turkey.


Wales centre Jamie Roberts admits the scale of their defeat by Australia was a "kick up the backside" ahead of their Test against Argentina on Saturday.

Roberts was at Twickenham in October for the Pumas' 33-21 loss to Australia.
"They'll play from their own half and they have big carriers, a physical side" he told BBC Wales Sport.
"Argentina will pose a similar threat [to Australia], with speed out wide. If we allow them speed of ball and space, it'll be another tough day."
"What we didn't do [against Australia], we have to do next week and that's meet them [on the gain-line] and stop their momentum" he added.
Argentina were 43-20 winners over Ireland in the 2015 World Cup on their last visit to Cardiff, and face Wales off the back of a 54-20 victory over Japan in Tokyo.
Wales should have Jonathan Davies available for selection in the second Autumn series game on Saturday, 12 November after a tight hamstring saw the centre pull out of the Wallabies encounter.
Full-back Liam Williams should also be fit again, flanker Sam Warburton played 80 minutes on his return for Cardiff Blues in Treviso, and lock Alun Wyn Jones is likely to be available after his family bereavement.
Improving Pumas
Roberts was one of only two Wales players to feature in a victory over Australia, back in 2008, but could not add another victory against the Wallabies on his 84th appearance for Wales.
"It's certainly a kick up the backside, we go into training and we have to address the issues. We've got to learn from it, I think the main thing to learn is to slow their speed of the ball. Argentina are a formidable outfit this year, I think they've improved a lot in these last few years" he said.
Roberts, who was partnered by Scott Williams after the late withdrawal of Jonathan Davies with a tight hamstring, says the scoreline has to galvanise the Welsh squad.
"It has to, but a lot of us have been there before. It was a bad day at the office but the guys will dust themselves off quickly and go again."
Moriarty bonus
One of the few positive points for Wales from the Australia match was the form of Ross Moriarty, with the Gloucester back-rower impressing in the number eight shirt. He was playing his first international  in the position in the absence of Taulupe Faletau.
"Personally I enjoyed the game, I felt comfortable at eight. Everyone's been saying how I'd never played at eight before but it didn't faze me.
"It's not too different [from flanker], my game's based round carrying and tackling and that's what I did. I just had to control the ball a bit more at the scrum and I felt comfortable. I'm just doing all I can to keep the coaches questioning who they pick."


British world champion Rachel Atherton does not feel the need to go chasing Olympic medals despite dominating downhill mountain biking.

Atherton, 28, became the first rider in history to complete a perfect downhill World Cup season and then won a fourth World Championship title a week later.
However, the downhill discipline is not an Olympic sport.
Atherton said: "I'm proud and content with what I have achieved. I don't need the validation of an Olympic medal."
Other British riders have changed disciplines in the pursuit of winning Olympic medals.
Mark Cavendish, the only member of the 2008 Beijing Olympic track team to miss out on a medal, returned to the velodrome for the 2016 Rio Games and was rewarded with silver in the omnium.
He quit this year's Tour de France early, after winning his 30th career stage in the three-week road race, to focus his attentions on Rio.
And four-time BMX world champion Shanaze Reade is also heading back to the more controlled environment of track cycling for the 2020 Tokyo Olympics.
Reade, who won world team sprint titles in 2007 and 2008 with Victoria Pendleton, missed out on Olympic BMX medals in 2008 and 2012 despite starting as favourite because of the "lottery" nature of the sport.
Atherton said: "I definitely used to want to switch to track at some point but in mountain biking you spend a lot of time outside in the mountains - I think I would miss that lifestyle.
"Mountain biking has a huge following and a life on its own without [downhill being included in] the Olympics."
The Trek factory rider has won 13 downhill World Cup races in a row, including all seven this year to win her fifth title.
Atherton could now target the two-day enduro races, which include both uphill and downhill sections.
"That would be a huge challenge, having the fitness to do that, but it is something that I would be pretty excited to give a go," she said.
And, after a year "beyond anything" she imagined, Atherton has returned home to a small village north of Aberystwyth for the off-season.
"It is surreal getting back into home life. It is pretty cool to bring the trophy home to this tiny village in the middle of Wales," she said.
"When you are at the top of your sport it is a stressful thing, it is hard to enjoy because you are so focused.
"I'm actually looking forward to a year enjoying racing a bit more and not having to prove myself is going to be nice."


A campaign to get people to pick up after their dogs launches on Wednesday.

A survey by Dogs Trust Bridgend found 52% of people in Cardiff said dog poo was their biggest bugbear in public places - above smoking and littering.
And 40% of those surveyed said they come across dog poo more than once a week, but 57% admitted being "too polite" to confront owners.
The Big Scoop campaign hopes to remind people they could be fined if they fail to clean up after their pet.
Alex Jackson, head of campaigns at Dogs Trust, said: "Dog poo is one of the biggest complaints received by local authorities every year.
"It's important that everyone is aware of how simple disposing of dog mess can be."
A spokesman from Cardiff council said dog fouling has "fallen significantly" since 2015, when a city-wide survey showed it was ranked as a third concern for residents after litter and fast food-related rubbish.
He said the council was changing the way it manages the streets by "bringing different service areas together to improve the cleanliness of all council land in neighbourhoods across the city".
"What is essential is that dog owners play their part and take responsibility for their animals by clearing up after them," the spokesman added.
"The same principle applies for those who litter our city; it isn't acceptable and will not be tolerated. We have to work together to ensure that Cardiff remains clean and tidy."


Police and experts in cybercrime are meeting in Wrexham to discuss ways to tackle the issue and keep people safe online.

Glyndwr University is hosting the first meeting of the North Wales Cyber Security Cluster with local businesses also attending.
Prof Vic Grout said the aim is to meet monthly to share good practice.
Security agency GCHQ said people and businesses could adopt basic cyber security principals to keep safe.


A train hit a car at a level crossing in South Lanarkshire.

The occupants of the car managed to escape from the vehicle before it was hit at Cleghorn level crossing in Lanark on Saturday evening.
It was struck by the Virgin service from Preston to Glasgow, which was carrying around 60 passengers just before 19:00.
The incident caused widespread disruption and services were re-routed as a result of the collision.
British Transport Police (BTP) said its officers were investigating how the vehicle came to be on the tracks.
In a statement published on Saturday, a spokesman for BTP said: "Just after 18:46 we were called to Cleghorn level crossing in Lanark following reports that a car was struck by a train.
"Officers from British Transport Police and Police Scotland are on scene and are being supported by the Scottish Fire and Rescue Service.
"Fortunately, all occupants of the vehicle were able to exit before it was struck by the train. There are no reported injuries at this stage.
"Our priority is to ensure the safety of everyone on board the train and the vehicle's occupants and look to understand how the car came to be on the tracks."
BTP also said the Rail Accident Investigation Branch and Office of Rail and Road have been notified.


Burton will check on midfielder Lasse Vigen Christensen, who missed the draw with Aston Villa because of a tight gluteal muscle.

Should Christensen remain out, Michael Kightly is likely to keep his place, while former Ipswich striker Luke Varney will hope for a recall.
Ipswich midfielder Cole Skuse is set to return to action, having missed two matches after suffering concussion.
Forward Tom Lawrence is expected to start after a groin injury.


Sam Vokes has admitted to surprise that Joey Barton gave up another shot at the Premier League to join Rangers.

Midfielder Barton helped Burnley to the Championship title this season and an instant return to England's top flight.
"I'm gutted that Joey has gone," said Wales striker Vokes, who scored 15 league goals for the Clarets this season.
"I was a bit surprised too because he was a big part of the squad and a key figure for us on and off the pitch."
Barton turned down a lucrative 12-month deal to stay at Turf Moor and has instead joined Rangers on a two-year contract following the Glasgow club's promotion to the Scottish Premiership.
The 33-year-old has had plenty of controversial moments in a career that has also taken in Manchester City, Newcastle United, Queens Park Rangers and Marseille.
But Vokes insisted: "He was good around the place. Even when we had a sticky patch around Christmas, he was a great leader in the dressing-room.
"People spoke about his reputation before he came in, but I didn't see that at all.
"I'm sure he will go up to Scotland and have a good crack at it.
"He was a big part of what we did, but he's made that decision and he'll go up there with the same energy that he had for us."
Vokes, speaking at Wales' pre-Euro 2016 training camp in Portugal, is excited about a return to England's top flight under manager Sean Dyche.
"The club is in a lot better position on the financial side after coming out of the Premier League the last time," suggested the 26-year-old.
"A few lads have signed new contracts and that shows the stability of the club and their intentions.
"The manager has been a massive part of the club's success over the last three or four years.
"I think he'll bring in a few players this summer and the club will have a go.
"We've got a stable group, but he will look to add a bit of quality."


Jared Payne will miss Ulster's crucial Pro12 match against Munster because of an ankle injury sustained in the draw with Cardiff Blues in Belfast.

Chris Henry is available again however after being absent for the Kingspan Stadium encounter with a niggle.
Munster duo Conor Murray and CJ Stander are likely to be ruled out as they continue their recovery from injury.
Murray has not played since suffering a shoulder injury when in action for Ireland against Wales on 10 March.
Stander sustained an ankle problem during the Irish province's Champions Cup quarter-final win over Toulouse.
Both players are now in a race to be fit for Munster's Champions Cup game against Saracens in Dublin on 22 April.
Munster Director of Rugby Rassie Erasmus conceded on Monday that scrum-half Murray's 'stinger' is more severe than first feared.
The Ireland international has been reported to be close to a return on a weekly basis but has not been available for selection and pulled out of his side's emphatic last-eight 41-16  win in Europe.
Stander was photographed wearing a prototype boot last week but Erasmus believes he is the more likely of the two to be fit to face the Champions Cup and Premiership champions.
Munster remain cautiously optimistic that the pair, who are both very much in the frame for selection for the British and Irish Lions tour to New Zealand, will make it with 11 days to go until the Aviva Stadium encounter.
Fly-half Ian Keatley is likely to return for the visit of Irish interprovincial rivals Ulster this weekend, while Donnacha Ryan and Tyler Bleyendaal are undergoing return to play protocols after suffering concussions.
Munster are challenging for honours on both the European and domestic fronts and boosted their chances of securing a home Pro12 semi-final by seeing off Glasgow 10-7 on Saturday night.
That victory left them seven points clear of third-placed Ospreys in the standings.

Ulster have dropped to fifth in the table, level on points with the Scarlets, who moved above them into fourth by defeating Treviso with a bonus point on Saturday.
Payne could return to face the Ospreys on 29 April as his side continue their quest for a place in the end-of-season play-offs.
Props Ross Kane and Kyle McCall are also nearing a return to full fitness.


A mother accused of murdering her baby boy had a photograph of him with a cannabis joint behind his ear, a jury heard.

Noah Serra-Morrison was 13-months-old when he died at his mother's home in Crawley Road, Luton, last November.
Prosecutors at Luton Crown Court claim the boy suffered a catalogue of injuries in the weeks before the massive head injury that killed him.
His mother Ronnie-Tayler Morrison and her partner Hardeep Hunjan deny murder.
The jury heard Ms Morrison, 21, had an iPhone with a photograph of Noah with a cannabis joint behind his ear.
And in a video clip on the same phone, the mother and Mr Hunjan were shown to the court smoking three cannabis joints at the same time through a home-made tube.
The baby died from a massive head injury inflicted on him at the flat in Crawley Road on the night of November 20/21 last year.
He was taken to the Luton and Dunstable Hospital, where he was pronounced dead in the early hours.
When he died it was found the child had suffered a series of fractures to his arms and legs, some new and some going back weeks.
The couple, said the prosecution, were to claim to that little Noah had injured himself by falling out of his crib.
That, said the crown, is impossible and the injuries found on the baby could not have been caused by an accident.
The case continues.


Azharullah's 6-68 gave Northamptonshire the upper hand on day one of their Division Two encounter with Sussex.

Rain prevented play until 14:30 BST at Arundel, two and a half hours after the scheduled 12:00 BST start, and Northants bowled first having elected not to contest the toss.
Azharullah took the first six wickets to fall to reduce Sussex to 139-6.
Only Chris Nash (75) offered real resistance as the hosts were all out for 178, with Northants 43-1 in reply.
Ollie Robinson struck to bowl Rob Newton for a 24-ball duck, but Ben Duckett and Alex Wakely held on until the close, which came just before 20:00 BST because of bad light.
Ottis Gibson was the last bowler to take all 10 wickets in a Championship innings, for Durham against Hampshire in 2007, and Pakistan-born seamer Azharullah appeared on course to match that feat until Ben Sanderson had Robinson caught at point.
While much of Sussex's batting line-up crumbled around him, opener Nash hit 10 fours in his 119-ball knock before he was the eighth wicket to fall.


A seven-year-old girl has died after she was hit by a skip lorry as she crossed a road in Coventry.

The girl, who has been named by police as Sophia McDonald, was on Henley Road, in Wood End, when she was struck by the "slow moving" lorry at about 16:00 BST on Tuesday, police said.
A GP from a nearby practice got to the scene before paramedics but the child was confirmed dead at the scene.
The girl's mother and the truck driver were treated for the effects of shock.
More updates on this and other stories in Coventry
A statement from Sophia's family said: "She was a beautiful angel, the happiest child with a beautiful cheeky smile.
"She was a very loving, kind hearted, happy-go-lucky little girl who loved her family. We are devastated at her loss."
Relative Donna Proctor told BBC News she was with the child's mother when the crash happened and they heard a "screech".
"My cousin was just running round and round in circles in the middle of the road just screaming.... there was nothing we could do for her daughter."
Meanwhile the employer of the driver involved said his employee was "absolutely broken-hearted".
Paul White, the managing director at Tom White Waste, based in Longford, said the man did not see the youngster as he made his way back to its site less than two miles away.
He added: "We're a family company. The vast majority of employees have got children. It's an absolute tragedy.
"We offer our condolences to the family."
St Laurence's CE Primary school, in Old Church Road, Coventry, said it understood Sophia was one of its pupils.
A statement said: "As you can imagine the school community is deeply shocked and saddened. We are currently helping pupils, staff and parents come to terms with this heart-breaking news."
Witness Joanne Taylor said: "People just covered her over with blankets.
"Obviously the ambulances came, the police came... the mother was distraught, just running around hysterically screaming 'my baby, my baby'. It was really upsetting."
The girl's mother and the lorry driver were taken to hospital.
The road was closed for several hours while emergency services investigated the crash.
Sgt Alan Wood, from West Midlands Police, who appealed to witnesses to contact the force, said: "This appears to have been a tragic accident; our thoughts are with the family of the little girl at this difficult time, who are being supported by specialist officers."


An out-of-hours GP service that serves more than one million people has been put in special measures by the Care Quality Commission.

Emergency patients were waiting too long to be seen and some medicines were out of date at Fosse House in Leicester, its inspectors found.
But, their report said patients were treated "with compassion and dignity".
Central Nottinghamshire Clinical Services, which runs the service, apologised to those affected.
The NHS service in Smith Way, Enderby operates across Leicester, Leicestershire and Rutland.
Under the CQC's new programme of inspections, all of England's GP practices and out-of-hours services are rated according to whether they are safe, effective, caring, responsive and well led.
After the inspection in March, Fosse Way scored "inadequate" in all areas but caring, for which it "requires improvement".
Emergency patients were waiting too long to be seen, the report said, and essential clinical equipment was found to be out-of-date and not available causing "inappropriate delays".
A spokesman for CNCS said it was already making the suggested improvements to waiting times and management of medication and equipment.
Janet Williamson, deputy chief inspector in CQC's central region, said "significant areas of concern" were found despite patients saying they were treated "with dignity and respect".
"We will continue to monitor this service and we will inspect again in six months to check whether improvements have been made," she said.
"I am hopeful that the service will do what is required for the sake of its patients but if we find that the service remains inadequate, we will consider taking further action."


Liverpool boss Jurgen Klopp says he is "not a clown" and will not ignore the problems his side face, having won just once in the Premier League this year.

The Reds, who lost 3-1 at champions Leicester on Monday, can move above Arsenal into the top four if they beat them on Saturday, kick-off 17:30 GMT.
Klopp's side won the reverse fixture 4-3 on the opening day of the season, which he says gives his side optimism.
"I am not always laughing like crazy. I am a normal person," said the German.
"We have this lack of consistency, we cannot ignore it. I am not a clown - even though a few people think I am.
"It is not about laughing the whole week and ignoring the problems you have."
Captain Jordan Henderson is out with a foot injury, but Klopp believes other players are taking responsibility on the pitch.
The former Borussia Dortmund boss also dismissed the suggestion his side need to be more physical.
"I think we are usually clean - not ugly challenges - but physical," he said. "Sometimes you need tactical fouls but being harder than allowed, I don't think it makes sense.
"I never force my players to make fouls. We are always a pretty fair team as even in a challenge we want to keep the ball and not break a leg.
"Being physical means being ready to hurt yourself not the other player."


Real Madrid captain Sergio Ramos has warned his team-mates not to get carried away despite the club's healthy lead at the top of La Liga.

The defender scored in stoppage-time to snatch a 1-1 draw at Barcelona on Saturday to ensure the leaders stayed six points clear of their rivals.
Real have not won the league title since 2012 under Jose Mourinho.
"It's better to have it in our own hands than depend on others," said Spain international Ramos, 30.
"We mustn't get carried away because there's still a long way to go in La Liga."
Real have one more La Liga game at home to Deportivo La Coruna on 10 December before the European champions fly to Japan to compete at the 2016 Fifa Club World Cup.
Barca finished one point ahead of Real to win the Spanish top-flight title last season.
Saturday's result at the Nou Camp could be critical should the title race come down to head-to-head records.
Real and Barcelona are scheduled to meet next in La Liga at the Bernabeu on 23 April 2017.
Ramos, a World Cup winner in 2010, added: "The points difference is reward for the hard work we've been doing since the start of the season.
"The hard work has reaped rewards and it's better to get one point than nothing at all.
"We have to keep picking up points and maintaining the gap from Barcelona."


The common toad is in decline across much of the UK and needs better protection, say conservationists.

Data from toad patrols - volunteers who move toads across busy roads - shows the toad population has fallen by more than two-thirds since the 1980s.
Once common in the British countryside, the amphibian is now on the brink of qualifying for protection as a vulnerable species, a study suggests.
Factors in its loss include urban sprawl and habitat fragmentation.
Silviu Petrovan, from the UK charity Froglife, said the information came from Toads on Roads - volunteer patrols established in the early 1970s to move toads over busy roads.
"Our data shows that hundreds of thousands of toads have been lost from the UK countryside in the past 30 years," he said.
The south-east of England has suffered the greatest declines in the common toad (Bufo bufo), according to the research.
Numbers have also fallen in Wales and the south-west and west of England in the past, but have stabilised in the last decade.
Central and northern areas of England as well as Scotland have also experienced declines.
In the east of England, numbers have recovered since 2005, but not enough to reverse previous losses.
Dr Petrovan said that conservation tends to be focussed on rare species, meaning more common species can get overlooked.
"We know now that a lot of the common butterfly species for instance have suffered really important declines and a lot of the farmland birds," he said.
"We didn't actually have enough data about common amphibians and this is why this data set is particularly interesting because it's showing that common amphibians such as common toads have suffered quite profoundly in the last three decades."
Froglife is calling for better protection measures for amphibians, including well designed wetland and ponds, and more toad tunnels under roads.
Paul Edgar, senior amphibian and reptile specialist from government conservation agency Natural England, said the common toad was "sadly on a downward trend".
"This is partly because of habitat fragmentation and so understanding and mitigating the impacts of this issue is vital," he said.
"We need to continue to build good quality habitat links across the wider landscape if we are to offer opportunities for this species to recover."
A similar decline in the common toad was found in Switzerland.
Dr Benedikt Schmidt from the University of Zurich said it was bad news that a once common species was becoming rare.
"We don't know what is causing the decline," he said.
"We believe it is a general deterioration of environmental quality - it could be land use, it could be mortality on the roads and it could be (in places where they are not protected) the use of pesticides."
The research is published in the journal, Public Library of Science ONE.

It seems unbelievable that two years on - apart from a few students who managed to escape soon after capture - not a single one of the 219 missing schoolgirls kidnapped from the Nigerian town of Chibok by the Islamist Boko Haram group in April 2014 has been found.

The British prime minister promised to help rescue the Chibok girls, as they had become known.
"This is an act of pure evil," David Cameron told the House of Commons.
"It has united people across the planet to stand with Nigeria to help find these children and return them to their parents."
But he was not speaking straight after the attack on the boarding school. Twenty-three days had gone by.
The Nigerian government in power at the time had initially denied the mass abduction had happened at all, then seemed not to care and this fuelled a local and international outcry via social media which put pressure on world leaders to act.
So what did Britain do after being pushed to make the promise to help? And was Nigeria willing to accept help?
"The UK, the French and the Americans provided surveillance and intelligence that was designed to deliver capability to the Nigerians that they did not possess," Dean Stevens, the former commander of the British Military Advisory and Training Team in Nigeria (BMATT), told me.
A team of British specialists was deployed and an RAF Sentinel spy plane joined others in the region - although initially it was delayed due to a breakdown.
In August officials said three unarmed RAF Tornado GR4 jets would also join the search.
They had a huge area to cover.
It was thought the Chibok girls were being held in the Sambisa Forest although there was also speculation that they had been split up and some had even been trafficked into neighbouring countries.
A few weeks later an aircraft that was part of the international effort spotted a group of around 80 people.  I am told that they could have been some of the Chibok girls.
"There was only one sighting of a large group of what was assessed to be females but that was not supported by any other intelligence," said Lt Col Dean Stevens, BMATT commander between March 2013 and March 2015. He said what was required was additional intelligence from Nigerians on the ground.
"Ultimately it was the responsibility and decision of the Nigerians to react to that information and they chose not to do anything with that information they received."
Mounting any rescue mission would have been extremely risky and the UK had history.
In 2012 British Special Forces tried to save Chris McManus and his Italian colleague Franco Lamolinara, who were being held by jihadists in north-west Nigeria. Both hostages were killed. Officials said the captors executed them just after the Nigerian and British troops had stormed the compound.
A year later another British construction worker Brendan Vaughan was amongst seven hostages killed by a Boko Haram splinter group which mistakenly thought a rescue operation was under way.
"It's hard enough and we British know this from bitter experience to get a single hostage out of an incident. To try and rescue hundreds when they may be split up is hugely dangerous," says James Hall, a retired colonel and former UK military attachÃ© to Nigeria.
"There must be a very significant danger if they are properly guarded and protected that many of them are going to be killed.
"So frankly I don't think even the best armed forces would have found this easy or would have been keen to do it unless they absolutely had to and the idea that the Nigerians could have done it is frankly ridiculous."
At the time Boko Haram jihadists were causing havoc - abducting hundreds of other largely undefended civilians, seizing territory and showing that Nigeria's military was no longer the regional force it used to be in the 1970s and 1980s.
"It was painfully obvious that they were very much a spent force. Their equipment was in very bad order, their training was frankly very weak. They still have some very good people but as an international force today they are very weak," James Hall told the BBC.
But could Britain and other countries have done more to help rescue the girls?
Boots on the ground were never likely given the complexities of the conflict and difficulties of working with the Nigerian army which has an extremely poor human rights record.  But I am told no more help was wanted.
"As far as actually dealing with the situation in the north-east, the Nigerian military and the politicians believed that they were capable of dealing with that and so neither asked for wanted or indeed accepted any of the offers for further help," said Dean Stevens.
That might seem a strange position for a country that at the time was losing a war against jihadists but there were other factors at play.
It is likely that some senior Nigerian officials in the former government would not have wanted these international partners to find out too much about its military which had been severely weakened by corruption.
Some British officials may have been quietly relieved that Nigeria was not calling for more direct help in the north-east.  It would have been an extremely difficult mission with enormous risk.
During their two years in captivity there have been other efforts to get several dozen of the girls released.
Stephen Davis, an Australian who had worked in the Niger Delta, got in contact with Boko Haram commanders and was on the verge of a breakthrough.
"Then as the girls were being taken to the agreed point for the handover, another Boko Haram group ambushed them and took them away," a former Nigerian official who at the time worked with the security services told me.
The Nigerian military effort has improved and thousands of civilians have been rescued from areas once held by the jihadists.
"It is a mystery that not a single one of the Chibok girls has been found among them. That suggests just how much of a prize the students have been to the group," the ex-official told me.
The UK and the US have increased their training programmes in Nigeria to help build the military's capacity to deal with the country's long list of security challenges. But due to human rights concerns there is a limit to what help they are willing to give.
"Sometimes it's a matter of doing business with the devil you know because the Nigerian military are not perfect by any means whatsoever but they are significantly better people than Boko Haram," says James Hall, adding it is a dilemma that needs to be carefully looked at.

Ulster Rugby has announced that their Ravenhill ground will be called Kingspan Stadium from now on following the signing of a 10-year agreement with the Cavan-based insulation company.

An Ulster statement said the agreement would "result in significant investment for the game of rugby at all levels".
The global company has been a sponsor of Ulster Rugby since 1999.
The agreement is understood to be a multi-million pound deal although the precise figures have not been released.

Ulster's announcement of the stadium naming rights deal for the redeveloped south Belfast ground mirrors the Irish Rugby Football Union's 2009 decision which saw the old Lansdowne Road venue in Dublin becoming the new Aviva Stadium.
Many other major sports stadiums throughout the world have gone through similar naming rights processes in recent years and Ulster argue that financial imperatives leave them with no option but to follow the same path.
"It's critical we get good quality investment into the stadium that we can reinvest in all of the game," said Ulster Rugby's chief executive Shane Logan.
When pressed on the sum of money involved, the Ulster chief said it was "substantial" and that the deal was "right up there at the top end" when compared with naming rights deals agreed by other top European rugby clubs in recent years.
Logan acknowledged that Ulster's decision may not go down well with traditionalists but indicated his confidence that the vast majority of supporters will be won over.
"I don't think we expect everybody to immediately get used to the name but as the with Aviva, the Etihad and other leading stadia, it does happen through time.
"We look upon it a bit like a marriage. When my daughter gets married, her name will change. It's perhaps a little bit similar. It's progress," added the Ulster chief executive.


Kite-maker Peter Powell, who developed a steerable kite with dual lines in 1972, has died, his family has said.

Mr Powell, 83, from Cheltenham, won the silver and gold diploma for his kite at the Exhibition of New Inventions and Techniques in Geneva in 1975.
In 1976, the Peter Powell kite was elected toy of the year by the British Association of Toy Retailers.
In a statement, his family said he died on 3 January "after a stroke and a short stay in hospital".
In the 1970s millions of Peter Powell kites were sold and flying steerable kites became a worldwide craze.
Mr Powell's son Mark said he was very happy producing about 300 kites a week until he appeared on the BBC television programme Nationwide.
"It went from 300 a week to 25,000, and we opened two factories but that wasn't enough so we opened three more making 75,000 kites a week - it was massive," said Mark Powell.
Film stars including James Stuart and Henry Fonda owned one of the kites.
Other tributes have been posted on social media.
Skip Cole wrote: "I originally owned a Peter Powell kite in the 70s giving me an amazing childhood."
Penny Merrie Was Wood said: "Due to him flying kites with lights on from Shurdington playing field, when some of the locals reporting seeing UFO's."
Mohammed Shahir of the One India Kite Team expressed "hearty condolence" to the family calling him "the father of stunt kites and legend in the history of kite flying".
James Linton recalled memories of growing up in New Zealand in the mid '70s as "the envy of my friends as they were a new phenomenon".
While Matthew Wynne said simply: "Every middle aged kiter's first kite. x"
Speaking to the BBC in 2014 Peter Powell said the fun of kite flying is "the freedom on the hills - you can steer it and just land it".
"What it leaves in the sky - it tugs at the heart strings - you'll never forget it."


The family of Emma Caldwell who was murdered in 2005 have appealed directly to her killer to give themselves up.

The family's lawyer Aamer Anwar said they wanted to express confidence in Police Scotland's new investigation.
He warned that this trust was "not unconditional" and that detectives from the original inquiry needed to answer for actions which had "betrayed Emma".
The family had been meeting the Lord Advocate James Wolffe at the Crown Office in Edinburgh.
Emma Caldwell, a 27-year-old heroin addict who had been working as a prostitute, was discovered dead in woods near Biggar in May 2005.
In May 2015, the Lord Advocate had told Police Scotland to reinvestigate her murder after the most senior officers in the Crown Office considered the case.
Reading a statement outside the Crown Office, Mr Anwar said the family had felt let down by the original investigation, which had failed to bring Emma's killer to justice.
He said: "The Caldwell family made it clear to the Lord Advocate that they had not forgotten that senior detectives from Strathclyde Police had betrayed Emma and they must answer for their actions one day."
He also said they had been frustrated about the length of time the new investigation was taking.
"The Lord Advocate tried to reassure the family that this is a painstaking complex investigation begun from scratch," he said.
Senior investigating officers told him that thousands of documents are being re-examined, which have generated numerous lines of inquiry that need to be investigated.
Police Scotland have also invited the Metropolitan Police to review its investigation strategy.
Mr Anwar said it had robust and painful meeting for the family, but they had welcomed "the dedication and commitment show by Police Scotland and the Lord Advocate to securing justice".
Making a direct appeal to the killer, he said: "Eleven years ago when you took Emma's life, you tore apart her family's lives forever.
"They were unable to bury Emma for some two years.
"Her mother Margaret has never been able to grieve and when William, Emma's father, died in 20001 he made his family promise they would never give up fighting for justice.
"Sadly it is inevitable that other women will have suffered at the hands of this killer and he will have aroused suspicions in his friends and family.
"The Caldwell family urges those who have such information to have the courage to come forward and speak to the police in total confidence."
After the meeting, a Crown Office spokesman said: "In May 2015 Crown Counsel instructed a re-investigation of the murder of Emma Caldwell.
"That investigation is complex and ongoing.
"The Lord Advocate today had the opportunity to meet with Emma Caldwell's family and to discuss the case with them."
The new investigation was launched after a BBC File on Four programme claimed that a local suspect was dropped in favour of prosecuting four Turkish men.
The programme revealed that officers who wanted to charge the local man, one of Emma's clients, were stopped by senior detectives investigating the Turkish suspects.
One of the Turkish men, who was charged with murdering Ms Caldwell, was awarded an out-of-court settlement after suing police for false arrest.
