UKIP will win at least five seats on the Welsh Assembly as part of a UK-wide "breakthrough" in Thursday's polls, its leader Nigel Farage has said.

He said his party was on course to win its first ever seats in Cardiff - where it is campaigning heavily - and in the Northern Ireland and London Assemblies.
It was "50-50" whether the party would gain representation in the Scottish Parliament for the first time, he said.
He declined to put a target on UKIP gains in English council elections.
UKIP is campaigning on multiple fronts as it seeks to become the only UK party to get people elected to the National Assembly of Wales, the Scottish Parliament and the Northern Ireland Assembly as well as the Greater London Assembly.
The party has focused much of its time and resources in Wales, where it won 13% of the vote in last year's general election.
Opinion polls suggest UKIP is set to win seats for the first time despite a row over its candidate selection process.
Mr Farage told the BBC's Daily Politics: "There will be a breakthrough in Wales. I think we are going to win five seats - we may do slightly better than that. Let's see."
As for England, Mr Farage would not be drawn on how many seats it would gain but said its record in local government was a good one and he predicted it would consolidate its position in its existing strongholds in Essex and South Yorkshire.
"We will make gains. To try and guess how many is virtually impossible. In Thurrock, I think we will become the biggest party on that council, in Rotherham we have a chance of becoming the biggest party on that council.
"There are 500 local UKIP councillors. Our local base is growing, the people who have had elected have behaved, on the whole, pretty well and been very diligent and worked very hard. Yes, we will improve."
There has been speculation about the future of the party, and a possible change in direction, whatever the outcome of June's referendum on EU membership.
Mr Farage said if there was a narrow vote to stay in the EU, a lot of Conservative and Labour supporters would be unable to reconcile themselves with the result and their party leadership's stance and UKIP could find itself "a lot bigger than it is now".
If there was a vote to leave, he said UKIP would need to "stay around" to ensure that the people's will was "implemented" but he conceded that it would need to show it could talk about issues other than Europe.
And he rejected suggestions that UKIP - which only managed to get one MP elected in last year's general election despite winning 12% of the vote - was treading water nationally, citing a recent YouGov opinion poll which put it on 20%.
"We are now at the highest we have ever been as a party - what more can I do?"


Funding the National Botanic Garden of Wales receives from Carmarthenshire council will be scaled down.

The council said funding would reduce from £70,000 this year to £50,000 next year and £30,000 in 2017-18.
The funding will be dependent on the garden improving its Welsh language usage and becoming more sustainable.
The garden said it was pleased the council had agreed to continue its support.
The council's executive board agreed in principle to a £50,000 grant for a regency landscape project - if a £6.7m heritage lottery bid is successful.
It said it wants to meet with Welsh government officials to discuss the level of support it provides.
The garden could work with the Mentrau Iaith project to become bilingual and look at further commercial ventures to draw in more visitors, councillors added.
Council leader Emlyn Dole said it needed change, direction and marketing.
Dr Rosie Plummer, the garden's director, welcomed the funding pledge towards the regency restoration project.
"We are pleased to hear, too, that councillors have agreed to continue to recognise the important contribution the garden makes to the area and to continue to support it," she added.


Pictures have been released in the US of the moment a father heard his dead daughter's heart beating inside the chest of a man whose life she saved.

Bill Conner heard the heartbeat after cycling hundreds of miles from his home in Wisconsin to Baton Rouge, Louisiana.
He shed tears while using a stethoscope to hear the heart of his organ donor daughter beating inside Loumonth Jack's chest. He received it after her death.
Mr Jack was told he had just days to live after suffering a heart attack.
"Knowing he's alive because of [my daughter] Abbey, Abbey is alive inside of him - it's her heart having him stand up straight," Mr Conner told CBS News.
"I was happy for him and his family, and at the same time, I got to reunite with my daughter."
Abbey and her brother were found unconscious in a swimming pool in January while on holiday in the Mexican resort of Cancun.
She was flown to Fort Lauderdale in Florida, where medics kept her on life support until doctors could use her organs for transplants. Her brother survived.
Mr Conner said that Abbey made the decision to be an organ donor when aged only 16.
"She registered. It's something that she knew a long time ago. Unfortunately, it came to fruition, but that's Abbey," he said.
"If you had her as a friend she always had your back, and for her to be helping people in need - that fits who she is."
Mr Conner decided to embark on his bike ride of more than 4,000km (2,600 miles) to raise awareness about organ donations and to visit the Broward Health Medical Center in Florida which was holding his daughter's body.
But in the course of his journey he became aware of the chance to meet Mr Jack on father's day when he was about 2,250km (1,400 miles) into his trip.

Why don't more African Americans become organ donors?
The clinic looking after Abbey's body had sent letters to the four recipients of four of her organs asking them to meet him. The four included Mr Jack, whose health had been rapidly deteriorating before receiving her heart.
"She saved me and I can't repay her. I wish I could but I can't," Mr Jack told WAFB in Baton Rouge. "All I can do is send my love to her family."
Witnesses have described the meeting of the pair as heartbreakingly poignant.
"It was unbelievable," Louisiana Organ Procurement Agency spokeswoman Mary Klemenok told the BBC.
"Abbey's willingness to donate her organs after passing away gave someone else a second chance at life.
"Bill was able to hear his daughter's heartbeat and record it so he can carry it with him for the rest of his life, which is absolutely beautiful."


Midfielder Joe Allen is showing the form that earned him a move to Liverpool, says former Swansea City team-mate Neil Taylor.

Allen left the Swans for Liverpool in 2012 but his time at Anfield has been hampered by injuries.
The 24-year-old played in his side's 1-0 win at Swansea and Taylor said: "I've always known he was a great player, we know in Wales what a good player he is.
"He just needed to be fit. He's a key player and he's in great form."
Taylor added: "He's had problems with injuries which he couldn't have helped, like when he got smashed in Andorra.
Allen has just over two years left on his current Liverpool deal but revealed he has opened talks with the club.
He has been in impressive form for Brendan Rodgers' Liverpool side of late and Taylor says Allen goes about his role in a quiet and effective manner.
"Unless you are a real football person and know the game and see the game like we do, because we're in it, then you may not see the nuts and bolts that Joe does so well," left-back Taylor added.
"It's massive. Look at Leon [Britton] down here over the years, he doesn't spray the passes like [Steven] Gerrard but the nuts and bolts to make your team tick, that's what Joe does.
"That's why Brendan took him there for a lot of money."
Allen and Taylor are set to be included in Wales' squad for the Euro 2016 qualifier against Israel in Haifa on 28 March.
Wales manager Chris Coleman will announce the squad on Wednesday with his unbeaten Wales side facing the Group B leaders.
"We all want to be in the team and we all want to qualify," Taylor added.
"These next few games are massive towards that. They're all big but now we feel we've really got a chance and we don't want to let that go."


A collection of more than 1,500 photographs by celebrated golf photographer Lawrence Levy has been launched to celebrate the Ryder Cup returning to Scotland.

The St Andrews University collection includes previously unseen images of now-classic Ryder Cup moments.
They are part of an archive of more than 10,000 Levy pictures from the 1980s and 1990s now available online.
Europe and the USA meet for the tournament at Gleneagles this week.
Lawrence Levy was the official photographer for the European Ryder Cup team, and spent 20 years devoted to taking pictures of the sport before he died of cancer aged 47.
The university's special collections team is digitising a collection of more than 250,000 photographs donated by the Joseph Levy Foundation, including 1,500 taken at Ryder Cup tournaments between 1979 and 1993.
The process of digitising the original photographs is ongoing, and collection cataloguer Trevor Ledger said more will be added to the online archive on a weekly basis.
He said: "The Lawrence Levy collection is one of the most complete photographic records of professional golf through the 1980s and 1990s.
"As official photographer for the European team, Lawrence held a unique position and was able to capture some incredible images from inside the ropes - indeed from inside the changing room too."
Images brought together in the collection include Sam Torrance clinching victory for Europe with a 22ft putt at the Belfry in 1985 before celebrating with Howard Clark, returning captain Tom Watson's win in 1993, and pictures of fans, families and media figuresl including Peter Alliss.


Filming started this week for the sequel to JK Rowling's Fantastic Beasts And Where To Find Them.

Warner Bros have now revealed more details of the plot, which is getting Harry Potter fans very excited indeed.
They have said the next instalment will include "surprising nods to the Harry Potter stories that will delight fans of the books and film series".
The first film was a massive success, so what else do we know about the next one?
According to Warner Bros: "JK Rowling wrote the [script] for the film, which opens in 1927, a few months after Newt helped to unveil and capture the infamous dark wizard Gellert Grindelwald.
"However, as he promised he would, Grindelwald has made a dramatic escape and has been gathering more followers to his cause - elevating wizards above all non-magical beings.
"The only one who might be able to stop him is the wizard he once called his dearest friend, Albus Dumbledore.
"But Dumbledore will need help from the wizard who had thwarted Grindelwald once before, his former student Newt Scamander.
"The adventure reunites Newt with Tina, Queenie and Jacob, but his mission will also test their loyalties as they face new perils in an increasingly dangerous and divided wizarding world."
Sounds pretty exciting, eh!?
So who are playing the main characters?
Well, Eddie Redmayne will return as Newt Scamander. Pirates of the Caribbean star Johnny Depp will be taking on the role of the dark wizard Gellert Grindelwald, while Jude Law takes on the role of young Albus Dumbledore.
Newt Scamander's war hero older brother will be played by a rising British star called Callum Turner.
Zoe Kravitz will play Leta Lestrange, while Claudia Kim will be a "featured attraction at a wizarding circus", where Skender (played by Olafur Darri Olafsson) will be the boss.
The film will move from New York to London and Paris.
The new film, which is directed by Harry Potter director David Yates, will be the second of five planned films. It is due to be released on 16 November 2018.


Northern Ireland First Minister Arlene Foster has criticised the Irish government's all-island forum on Brexit.

Mrs Foster described it as a "grandstanding exercise" and said she had better things to do than be a "lone voice among remoaners".
She has already declined an invite to attend next week's "civic dialogue" event in Dublin.
The forum was established in the wake of the EU referendum result.
"It's a complete grandstanding exercise," said Mrs Foster.
"It will be full of people who quite frankly haven't accepted the referendum result going down to talk about how dreadful it is and how awful it is.
"Mark my words that's exactly what will happen at the grandstanding forum that will come about.
"I'm not going to be a part of that. I am in this to do real business and to have outcomes, not to sit around talking about how dreadful it is."
Irish Prime Minister Enda Kenny has said the event will facilitate an all-Ireland conversation among the business community, wider civic society and politicians.
Asked if it would be valuable to put the argument in favour of Brexit to forum delegates, Mrs Foster replied: "To be a lone voice amongst a whole lot of remoaners?
"No thank you - I have better things to do with my time."


Wycombe have cleared off a debt in the region of £1m to ex-owner Steve Hayes through a Jordon Ibe sell-on clause.

Ibe came through Wycombe's youth ranks before moving to Liverpool in 2012 and joined Bournemouth in a Cherries club-record £15m move this summer.
When Hayes handed over the League Two side to the Wycombe Wanderers Trust in 2012, it was agreed a seven-figure fee would be paid over 10 years.
That has now been paid six years early, with a nominal surplus left over.
Hayes, whose debt owed by the club was interest-free, has also made a "significant donation" to the Trust as a goodwill gesture.
Chairboys chairman Andrew Howard said: "Steve was incredibly supportive of the club during the change of ownership and helped to ensure that Wycombe Wanderers could continue.
"This turn of events marks the end of an era and I would like to place on record our sincere thanks to Steve for everything he has done."

Eurozone businesses grew at the fastest rate in nearly six years in March, led higher by France and Germany, a closely-watched survey has indicated.

The latest Markit Composite Purchasing Managers' Index (PMI) rose to 56.7 from February's 56.0. A reading above 50 indicates growth.
The findings signalled the bloc's recovery was "surging higher", the report's authors said.
Job creation was at its best level for almost a decade, they added.
Chris Williamson, chief business economist at IHS Markit, said: "The eurozone economy's throttle opened further in March, with business activity and hiring surging higher."
The PMI measures companies' trading activity, giving a good idea of how well the underlying economy is performing.
Fuelling the growth were strong performances from France and Germany's services sectors, the survey found.
"Perhaps the best news came from France, where growth has risen above that seen in Germany, led by strengthening domestic demand," Mr Williamson said.
"While elections remain a worry regarding the outlook, for now the business mood in France and across much of Europe is very positive."
Economists said the PMI data could encourage the European Central Bank (ECB) to move towards raising interest rates and further easing its monthly bond-buying programme.
"Strong eurozone PMIs increase chances for first ECB exit package in June. A package, no action, though," said Carsten Brzeski, chief economist at German bank ING-DiBa.
â€ŽFrederik Ducrozet, senior economist at Pictet, said the ECB would wait for inflation to pick up further and see the outcome of the French presidential election before making a decision.
Is it finally looking like a half decent recovery? Let's not get carried away.
There's the scar of Greece. There's persistent unemployment, especially among young people.
The eurozone youth unemployment rate is one in five, and it's a lot higher than that in several countries.
And the economy is supported by the ultra-easy money policies of the European Central Bank; a negative interest rate and quantitative easing.
There are also persistent problems nagging at the eurozone banking system.
That said, the jobs situation has been moving in the right direction and inflation has risen to a level that has surely dispelled the ECB's worries about the dangers that can come from deflation or falling prices.
It does look like a small if still uncertain glimmer of light on the eurozone's economic horizon.


Dundee leapfrogged Motherwell as victory in Neil McCann's first game as manager left the home side in the relegation play-off spot.

Motherwell dominated the first half, but Mark O'Hara put Dundee ahead with their first chance in the final minute.
Marcus Haber swept home the visitors' second before Louis Molt's instant reply, but Haber claimed Dundee's third after O'Hara met Craig Wighton's cross.
Chris Cadden gave Well hope with 10 minutes left, but Dundee held on.
Victory at Fir Park meant they ended a run of seven straight defeats, which cost former manager Paul Hartley his job.
They also moved above Hamilton - beaten 2-0 by Kilmarnock - into ninth place, eight points clear of bottom side Inverness.
The last time Dundee visited Fir Park back in late February, they left Lanarkshire with a 5-1 win.
But the change in fortunes at Dens Park since that day - with only two goals in those past seven matches - resulted in a change of manager.
Motherwell started like a side buoyed by their comprehensive win over Inverness in their last league outing.
They stroked the ball around with confidence, dominated the midfield and created several chances but could not convert them.
Moult was his usual lively self but sent a half-volley straight at Scott Bain, the Dundee keeper also scrambling well to keep out a mis-hit Cadden cross.
Just as the first half appeared to be ending goalless, the visitors got the breakthrough against the run of play.
Haber's initial shot was blocked by Craig Samson, but O'Hara was quick to pounce and poke it home.
A mini goal-fest followed early in the second half, Haber extending Dundee's lead from close range after O'Hara's initial effort was blocked.
Moult controlled a corner with his first touch and fired home his 17th goal of the season with his second to pull a goal back for the hosts.
However, O'Hara stooped to meet Wighton's cross with a fabulous diving header, which appeared to touch Haber on the way in.
Dundee set out to defend what they had as Motherwell chased the game.
They thought they had pulled a goal back through Ben Heneghan's header, but referee Steven McLean deemed it had not crossed the line.
Moments later, Cadden did slide in at the back post to give the home side hope.
Despite throwing everything they had at Bain's goal, a leveller eluded the Steelmen, who are right back in the basement battle with four games left.
Motherwell manager Stephen Robinson: "I'm obviously very disappointed. Another incredible decision.
"We've seen it again and it's probably the worst of any of the decisions so far.
"When he [Dundee's Tom Hateley] clears it, his foot is actually in the back of the goal. It's an incredible decision.
"These people have clubs' livelihoods on the line, people's personal livelihoods on the line, and it's incredible that we haven't done anything about it. It should have been 3-3.
"Take that aside, though, and the two goals we lost either side of the first half were from really poor defending.
"We weren't going to go down today and we weren't going to stay up so we are well aware of that. We have to take it for what it is."
Dundee interim manager Neil McCann: "I am very proud of everyone connected with the staff, but especially the players.
"To come away with three points with a team that had lost seven games on the bounce, I couldn't be prouder.
"We knew we could break and get what we wanted. We looked a lot more purposeful going forward in the second half, and we knew Motherwell would put balls into our box, but we were set up for that.
"It was nervous towards the end, but I couldn't be happier. I wanted to take that fear away and it's difficult with a side that has been struggling to find results.
"But it just shows you what is in there and the character they have.
"We have got ourselves into a better position, but that is all. Now we start gearing up for Kilmarnock next week.
"But I am going to enjoy tonight because all the hard work we have done together has got us three points."

The housing market "paused for breath" across the UK in July and went into reverse in London, surveyors have said.

Demand for UK homes fell for the first time since the start of last year, according to the Royal Institution of Chartered Surveyors (Rics).
This, and sales, fell more sharply in London than elsewhere, while the number of homes for sale increased.
Concern over affordability was one factor for the shift, although prices were still expected to rise.
Surveyors suggested that property price growth was likely to be faster outside of London than in it.
"The shift in the mood music amongst potential buyers in the London market has been particularly pronounced, but that is in a sense consistent with the move to a more sustainable market in the capital," said Simon Rubinsohn, chief economist at Rics.
"Elsewhere around the country, the market in general is showing a greater degree of resilience, but that largely reflects the fact that in some areas, the recovery has only recently taken hold and affordability is rather less stretched."
Activity has slowed in the past after a so-called "Spring bounce" in the housing market, as potential buyers' thoughts turn to holidays in the summer rather than homes.
However, surveyors suggested that the market might have changed, owing to the prospect of higher interest rates and warnings from the Bank of England that it was keeping an eye on any risk of a housing bubble.
However, the Bank's governor, Mark Carney, may have eased the fears of some mortgage holders in the Bank's quarterly inflation forecast.
He said on Wednesday that whenever interest rates did increase, they would still do so gradually.

Cancer patients have been promised faster access to innovative medicines by NHS England.

It has announced changes to the heavily criticised and regularly overspent Cancer Drugs Fund, which pays for drugs the NHS has deemed unaffordable.
The new system will start in July 2016 and have a fixed budget of Â£340m.
No patients receiving drugs on the old Cancer Drugs Fund will have their medication stopped.
At present, the CDF can choose to pay for innovative drugs the health watchdog, the National Institute for Health and Care Excellence (NICE), has rejected for widespread use on the NHS.
But under the new system, NICE will make all the decisions.
By the time a drug comes on to the market, NICE will give it a yes, no or maybe rating.
Those given the go-ahead will be routinely offered across the NHS while those given a maybe rating can be considered for the CDF.
However, there will be "clear entry and exit criteria" to ensure money is spent on only the best breakthrough drugs.
Bruce Keogh, medical director at NHS England, said: "Improving cancer care is an absolute priority for NHS England... that is dependent on access to treatments.
"[The CDF] will provide faster access for patients, I think that's really important, and I think it will bring clarity to which drugs are the most effective sooner than we know at the moment."
The fund, which was established in 2011 and covers England, has seen its costs rise to Â£340m in 2015-16 from an initial annual budget of Â£200m.
An NHS official said: "Drug companies will need to price their drugs responsibly, and we make no apology for maintaining the pressure on this point on behalf of the public.
"Companies keen to work with the NHS for patients will get a new fast-track route to NHS funding for promising new drugs, backed by a speeded up and more transparent NICE assessment process."
Dr Paul Catchpole, from the Association of the British Pharmaceutical Industry, said: "If cancer medicines go through more or less exactly the same NICE appraisal process that was in place five years ago - which necessitated the setting up of the CDF in the first place - we will largely get the same answers as before - the majority of medicines will be turned down.
"Without substantial changes the ABPI estimates that under the proposals two thirds of existing CDF medicines are likely to no longer be available to NHS patients by the end of the year."
Target Ovarian Cancer chief executive Annwen Jones said: "Important questions remain unanswered with this proposal.
"The Cancer Drugs Fund must retain the power to make a real difference to people's lives in the face of budget cuts."

North Ferriby United ended a run of eight-straight National League defeats with a point in a scrappy game against Wrexham.

Wrexham's Gerry McDonagh had the best opportunity of the first half but he missed from six yards.
Home keeper Rory Watson denied Callum Powell and John Rooney twice fired wide as Wrexham drew a third successive game.
A point was enough to see North Ferriby move off the bottom of the table.
Wrexham remain 14th in the table and Dean Keates' side are nine points off the play-off places.
Wrexham manager Dean Keates told BBC Radio Wales Sport: "You look at the overall game and there was only one clear cut chance, on the stroke of half-time, and he's [McDonagh] got to score.
"It was very frustrating with not enough chances created on our behalf.
"It wasn't good enough and the intensity wasn't high enough. We played the game at their tempo and let them slow it down."

These days study into artificial intelligence research is no longer the preserve of universities - the big technology firms are also keen to get involved.

Google, Facebook and others are busy opening AI labs and poaching some of the most talented university professors to head them up.
Prof Yann LeCun is a hugely influential force in the field of Deep Learning and is now director of AI research at Facebook.
He spoke to the BBC about what the social network is doing with the technology and why he thinks Elon Musk and Stephen Hawking are wrong in their predictions about AI destroying humanity and here are his thoughts.
What is artificial intelligence?
It is the ability of a machine to do things that we deem intelligent behaviour for people or animals. Increasingly it has become the ability for machines to learn by themselves and improve their own performance.
We hear a lot about machines learning but are they really thinking?
The machines that we have at the moment are very primitive in a way. Some of them, to some extent, emulate the basic principles of how the brain works  - they are not at all a carbon copy of brain circuits but they have a little bit of the same flavour.
They are very small by biological standards. The biggest neural networks that we simulate have in the order of a few million simulated neurons and a few billion synapses - which are the connections between neurons - and that would put them on par with very small animals, so nothing like what we would think as humans.
In that sense they are not thinking and we are still very far from building machines that can reason, plan, remember properly, have common sense and know how the world works.
But what they can do is recognise objects and images with what seems to be superhuman performance at times and they can do a decent job at translating text from one language to another or recognising speech. So in that sense they do things that humans would consider an intelligent task.
Intelligent Machines - a BBC News series looking at AI and robotics
How do these machines actually work?
A lot of the machines we are building are artificial neural networks. They do a very large number of simple operations which essentially come down to multiplication and addition.
Those large networks of simulated neurons each of which is connected with several thousand other neurons - some of which come from pixels of an image or an audio signal. It performs a simple operation, something like a weighted sum, of all those values. There are billions of operations to perform.
We organise the neurons in layers - the architecture of this is inspired by visual cortex in mammals - and we can train the machines to recognise objects by showing them thousands of examples.
If we want the machines to recognise aeroplanes, cars, people and tables, we collect lots of images of these things and show them to the machine one after another.
If it gets it wrong, we figure out a way to adjust the strength of the connections between neurons so the next time around it knows what it's looking at.
What is Facebook doing with AI?
Facebook's mission is to connect people with each other and increasingly that means facilitating communication between people but also connecting them with the digital world in their daily lives.
One of the dreams we have had for years is some sort of intelligent agent that seems clever enough to do a lot of tasks, including organising meetings with friends and accessing information that might take you an hour or two on Google.
If we have machines with a little bit of common sense, know a little bit about how the world works and which know you and your interests it could be very useful to you. That's the long-term goal.
In the meantime we can use those technologies to do a lot of useful things - selecting content that might be interesting to them, filtering objectionable content, translating an image into text for the visually impaired, things of that type.
Facebook has launched a rival to Siri. What's that project about?
It is a project called M - it is indeed an assistant to which you can ask just about any question or to solve any problem.
Some of the questions may require human expertise - so whenever the machine can't answer a question it is sent to human trainers and then the machine can learn to do a better job next time. As we get more experienced with the service, we will be able to build machines that do more automatically and scale the service to more people.
What we are hoping to do is take this digital assistant idea to the next level. If you think about Siri, Cortana, Google Now - most of the answers they provide are scripted. Someone has imagined the possible answers and figured out a tree of possibilities. If you go outside of the script, the machines responds with a joke or tries to get out of it.
All of its behaviour is programmed by humans but what we are trying to do with M is test the ability of a machine to learn.
It is very ambitious, very risky and just a small experiment for the moment but we will see how it goes over the next year or two.
We are very excited about it because it is really the essence of AI - a machine that you can talk to and that can help you.
Elon Musk and Stephen Hawking are worried about the threat AI poses to humanity- where do you stand?
I don't stand with them. First of all you have to realise that a lot of the people that make those statements are not themselves AI researchers.
In the case of Elon Musk, he is very interested in existential threats to humanity - that's why he builds rockets to go to Mars in case something bad happens on Earth.
In the case of Stephen Hawking, his thinking has evolved because since he became vocal on the subject he has talked to AI researchers. Also his motivation, his timescales are millions and billions of years - and what can we say about humanity in a billion years? It is very hard to say.
That said, AI is already a powerful technology and it is going to become more powerful. Every powerful technology has the potential to be both very beneficial and very dangerous so we have to think about what we are doing.
You don't buy into the killer robot scenario then?
Robots taking over the world, Terminator-style or Ex Machina style - these are entertaining topics but they are not realistic at all.
As humans we have a hard time imagining an intelligent entity that doesn't have all the drives and failings of humans because humans are the only example of an intelligent entity that we are familiar with.
Humans have all kinds of drives that make them do bad things to each other, like the self-preservation instinct and the need to have access to food which leads into the need to have access to power and the desire to reproduce.
Those drives are programmed into our brain but there is absolutely no reason to build robots that have the same kind of drives.


A 17-year-old boy has appeared in court accused of planning a terror attack in Cardiff.

The teenager, from Rhondda Cynon Taff, has been charged with obtaining a knife and hammer and preparing a suicide note for an attack on 30 June.
He has also been charged with posting an image and comment on Instagram to encourage others to commit acts of terror.
He appeared at Westminster Magistrates' Court, sitting as a youth court.
Wearing a dark jumper and light grey trousers, he stood to confirm his name, address and date of birth.
He folded his arms and at one point appeared to wipe his eye.
The teenager was arrested on 30 June by officers from Wales Extremism Counter Terrorism Unit (WECTU) working jointly with West Midlands Counter Terrorism Unit and MI5.
Senior district judge Emma Arbuthnot, the chief magistrate, remanded him to youth detention accommodation.
He will appear at the Old Bailey on 20 July.


A bus passenger was knifed to death during a row with a stranger on the vehicle's upper deck, a court heard.

Kieran Gillespie, 25, from Birmingham, denies murdering Leon Barrett-Hazle in Handsworth in the city on 23 January, claiming he acted in self-defence.
Mr Gillespie told police he had pulled "a pair of scissors" on his victim after believing he had been stabbed in the face.
Mr Barrett-Hazle, 36, from Smethwick, West Midlands, was found to be unarmed.

The jury at Birmingham Crown Court was told the bus's CCTV would show a row breaking out between the men, with Mr Barrett-Hazle punching Mr Gillespie in the face.
Mr Gillespie, of Wellesbourne Road, fled the scene in Rookery Road but returned to the bus to recover his baseball cap after the stabbing, the prosecution said.
After his arrest, he told officers a disagreement arose because Mr Barrett-Hazle kept looking at him on the back row of the 11A bus.
Stephen Linehan QC, prosecuting, said tests showed Mr Barrett-Hazle's multiple stab wounds could not have been caused using scissors.
The barrister said: "He drew that weapon and we say you'll conclude it was a knife of some type.
"In interview, Gillespie said he stabbed him two to three times - it was far more than that."
The trial continues.


The Bishop of Sodor and Man says he will retire later this year.

The Right Reverend Robert Paterson, 67, has served the Diocese of Sodor and Man since 2008, as well as holding a seat on the island's Legislative Council.
He told Manx Radio his decision to retire on 11 November was motivated "purely by age".
Sodor and Man is the smallest diocese in the Church of England, overseeing 45 churches and 27 parishes.
Before moving to the Isle of Man, he was a parish priest in Wales and chaplain to the Archbishop of York, John Sentamu.


A couple in charge of a dog which attacked two women in separate incidents have been jailed and banned from keeping dogs for 20 years.

Sylvia Baillie, 60, was bitten on the cheek by the Japanese Akita in Paisley in July 2016, while Jane Darroch, 72, suffered arm injuries a month earlier.
Leeane McHugh, 35, and Patrick Maher, 46, had previously admitted separate dangerous dog charges.
A court heard the pair had failed to help during the attack on Ms Baillie.
Sheriff David Pender sentenced them both to 12 months in prison, pointing out that dog wardens had previously told them to keep the dog on a short leash - advice they had not followed.
He also ordered the Akita to be destroyed and banned the couple from keeping dogs until 2037.
He awarded compensation of Â£1,000 to Ms Baillie, the couple's neighbour, and Â£500 to Ms Darroch, Maher's aunt.
Ms Baillie was attacked in McHugh and Maher's Paisley home on 13 July last year after a funeral.
Procurator Fiscal Depute Alan Parfery told Paisley Sheriff Court that as Ms Baillie left she went to wave goodbye to the dog which then bit her on the face.
"The dog's jaw locked, for what's described as a few seconds, before her daughter grabbed the dog and pulled the dog away," Mr Parfery said.
"Neither [McHugh of Maher] did anything during that period of time.
"They were both in the room and [McHugh], the owner of the dog, did nothing during that time, albeit it was a short time."
Maher took the dog out of the living room and later told police that it ran outside his flat.
McHugh tried to treat Baillie's injuries and the police and ambulance were called.
Mr Parfery added: "When emergency services arrived they found the 60-year-old [Sylvia Baillie] with a wound to the left side of her face.
"The injury was very severe and she is permanently disfigured.
"Doctors are unable to say how many stitches were applied as they were both external - to the face - and inside her mouth.
"There were so many stitches inserted, the doctors could not say."
The dog bit Maher's aunt two weeks earlier, on 30 June while it was tied up outside her home.
Following the attack, Ms Darroch's wrist bone was exposed and she had to have 12 stitches.
Maher and McHugh each admitted a charge under the Dangerous Dogs Act 1991 - that they were in charge of a dog that was dangerously out of control and left its victim scarred for life.
Defence solicitor Gordon Ritchie, representing Maher, described the attack on Mrs Darroch as "a particularly distressing incident."
He said Maher had been in the grip of a serious alcohol addiction at the time.
The lawyer said: "There was nothing to suggest, as far as he was concerned, for the dog to attack and inflict injury on a member of the public."
Lawyer Mark Fallon, representing McHugh, said it was "a unique and unusual" case.
He said the incident involving Ms Baillie "had some degree of predictability" but McHugh "felt she'd taken enough steps" to ensure the public was safe from the dog in her own home.
"She's full of regret", Mr Fallon said. "They had been friends for years and this has caused irreparable damage to that friendship."
Sheriff Pender said: "There's no doubt, by the time Mrs Baillie was bitten, it must've been very clear the dog had a vicious propensity.
"You took no steps to ensure people visiting your home were safe from the dog."
The pair earlier had other dangerous dog charges dropped for agreeing to admit guilt in relation to the attacks on Ms Baillie and Ms Darroch.
Outside court, Ms Baillie said: "I've never been the same since the attack. I can't bear dogs or to be near dogs now. I still get flashbacks."


Power has been restored to 2,000 customers left without electricity in Londonderry on Friday.

The electricity fault was reported in the Woodburn area of the city at around 11:20 BST.
All affected customers had their power restored by 16:00 after the fault was repaired. NIE Networks have apologised for any inconvenience.
City centre businesses and traffic lights were affected by a major fault in February.


The most senior US senator, Democrat Daniel Inouye of Hawaii, has died of respiratory problems at the age of 88.

Inouye had served in Congress since 1959, when Hawaii became a state, and had been a senator since 1963.
He also received the Medal of Honor, the US' highest military honour, losing an arm but destroying a Nazi bunker during a battle in Italy.
He was the first Japanese-American in Congress and most recently chaired the powerful appropriations committee.
According to a statement from his office, Inouye's last words were "Aloha".
In a statement, President Barack Obama said "our country has lost a true American hero".
Senate Majority Leader Harry Reid announced Inouye's death on the Senate floor on Monday. The Hawaiian senator was president pro-tempore of the Senate, third in the line presidential succession.
"His service to the Senate will be with the greats of this body," Sen Reid said.
"He had every reason to call attention to himself, but never did," Republican senate minority leader Mitch McConnell said.
"He was the kind of man, in short, that America has always been grateful to have, especially in her darkest hours: Men who lead by example and expect nothing in return."
Hawaii Governor Neil Abercrombie will appoint Inouye's replacement. The seat is up for re-election in 2016.
Born in 1924 in Honolulu, Hawaii, Daniel Inouye volunteered for US army shortly after the Japanese attacked Pearl Harbor in 1941, joining the famed Japanese-American 442nd Regimental Combat Team. He was 17 at the time.
"I tried to put myself in the shoes of my neighbours who were not Japanese," Inouye said about signing up.
"I felt that there was a need for us to demonstrate that we're just as good as anybody else.  The price was bloody and expensive, but I felt we succeeded."
In 1945, Inouye lost his arm in the battle that would later win him the Medal of Honor.
While he was leading a charge on German machine gun nest in Italy, he was shot in the abdomen, but managed to throw two grenades before his right arm was shattered by a German grenade.
"Despite the intense pain, he refused evacuation and continued to direct his platoon until enemy resistance was broken and his men were again deployed in defensive positions," his citation for the medal read. "In the attack, 25 enemy soldiers were killed and eight others captured."
The senator received the honour in 2000, after the junior senator from Hawaii at the time, Daniel Akaka, got Pentagon officials to review records to determine if some had been denied the honour because of racial bias.
Inouye was one of 22 Asian-American World War II veterans who belatedly received the medal, many from the 442nd regiment.
During his convalescence from his injuries, Inouye met Bob Dole, the future majority leader of the Senate and 1996 Republican presidential candidate, who also was recovering from severe war injuries. The two later served together in the Senate for decades.
But Inouye returned to a still-hostile America. On his way home from the war, he often recounted, he entered a San Francisco barbershop only to be told, "We don't cut Jap hair."
While Inouye was popular senator in Hawaii, especially due to the federal investment he brought to his state, he largely avoided the spotlight.
In 1968, President Lyndon Johnson urged Vice President Hubert Humphrey, who had won the Democratic nomination for president, to select Inouye as his running mate, to silence  the vice-president's critics on the Vietnam war.
But the senator was not interested. In 2008, his chief of staff said Inouye was "content in his position as a US senator representing Hawaii".
Inouye also served on the congressional committee that investigated the Watergate affair and recommended impeachment proceedings against President Richard Nixon.
A decade later, he served as chairman on another investigation committee, an inquiry into Iran-Contra affair, questioning top Reagan White House officials.


Two 13-year-old boys have appeared in court charged with attempted murder after a gang attack on a man in Renfrewshire.

The teenagers are among seven people accused of attacking the 39-year-old in Forbes Place, Paisley, on 24 September.
They were released on bail after appearing at Paisley Sheriff Court.
Two 16-year-old girls, and two others aged 15 and 17, also face charges in connection with the attack as does another boy, aged 15.
One of the 13-year-old boys appeared in court on Wednesday, while the other appeared separately on Thursday.
The 15-year-old boy appeared in court on Wednesday and was also granted bail.
Two teenage girls, aged 15 and 16, were charged in connection with the attack on Tuesday.
They made no plea or declaration and the case against them was continued.
The 16-year-old girl was remanded in custody, while 15-year-old was released on bail.
Two boys aged 16 and 17 were due to appear in court on Friday but were released without appearing in the dock.
They have been reported to the procurator fiscal and inquiries are continuing.


Three children died during an inspection into a council's "inadequate" children's services, an Ofsted report has revealed.

An investigation into the deaths is ongoing, after "serious failures" were found in Lancashire County Council's child care services.
The report said it was "too soon" to establish if the children's unrelated deaths could have been prevented.
The council said it was addressing the concerns "quickly and effectively".
The report said all the council's child care services had "significantly deteriorated" since the last inspection in 2012, when the authority was found to be good overall.
It said: "During the inspection, three children tragically died in unrelated incidents.
"Their families were open cases to children's social care and they were receiving services as children in need."
The report said an investigation into the children's circumstances were at an early stage, but noted that records connected to the children showed inadequacies.
"Some of this poor practice was seen in a much larger number of cases where children had not been harmed," the report continued.
The inspectors' widespread concerns include:
The report praised the council for the way children are listened to, and the way the risks of child sexual exploitation were tackled.
The authority said it had begun implementing a number of changes, backed by a new Â£5m investment.
Matthew Tomlinson, cabinet member for children and young people, said: "The children and young people who need these services deserve the best care and support, and we are very sorry that in some cases they have clearly not been receiving it.
"The council must now act quickly and effectively to resolve the problems identified during the inspection."
Analysis by Chris Rider, BBC Radio Lancashire political reporter
Three years ago, Lancashire County Council received a glowing report from Ofsted for protecting the region's most vulnerable children.
Now the picture painted by the watchdog is very different - its damming report pulls no punches and is littered with phrases like "serious failures".
While staff in children's services work hard, many do not have the right qualifications or experience.
The man in charge, Matthew Tomlinson, has apologised and pledged to invest an extra Â£5m to help turn the situation around.
But the leader of the council's opposition Conservative group, Geoff Driver - who led the authority at the time of the 2010 "good" Ofsted rating - wants Labour duo Mr Tomlinson and council leader Jennifer Mein to fall on their swords.


The rapids at the Kalagala Falls in Uganda are considered some of the best in the world, attracting both tourists and professional kayakers.

2 October 2016 Last updated at 09:13 BST
However, this holiday hotspot now finds itself at the centre of a debate about how the country should use the Nile River to fuel its economy.
The government is building a dam to increase a much-needed energy supply. But in turn the dam will submerge the rapids, damaging the tourism industry.

Later on Wednesday, Ken Skupski and fellow Briton Jocelyn Rae earned a thrilling victory in the mixed doubles to set up a quarter-final tie against top seeds Jamie Murray and Martina Hingis.
Skupski and Rae won 5-7 6-4 9-7 against ninth seeds Max Mirnyi and Ekaterina Makarova in fading light on Court One.
The British pair needed two and 21 minutes before Rae, a 26-year-old from Nottingham, served out their third match point.


Moonlight, a film about a boy growing up gay, black and poor in Miami, has cleaned up at the Gotham Independent film awards in New York.

The coming-of-age drama took best feature, best screenplay, best ensemble and the audience award.
The film stars Naomie Harris and newcomers Trevante Rhodes, Ashton Sanders and Alex R Hibbert.
Moonlight has made $8.5m (Â£6.8m) so far, making it one of 2016's biggest indie hits.
The film is based on Tarell Alvin McCraney's play titled In Moonlight Black Boys Look Blue and was produced by Brad Pitt's Plan B.
It was nominated for six Independent Spirit Awards last week.
As he accepted one of the awards on Monday, director Barry Jenkins said: "When I made this film, I thought five people would watch it."
The film will be released in the UK in February although it was also shown during the London Film Festival in October.
On the same day as the awards, the African American Film Critics Association (AAFCA) released a statement, praising 2016 as the best year for diversity in both casting and storylines.
"The studios and major film distributors really gave it to us this year," said AAFCA co-founder and president Gil Robertson.
"By any measurement, it's been an exceptional year for blacks in film. From comedies to high-quality dramas and documentaries, 2016 will forever represent a bonanza year for black cinema, and all cinema really."
Other big winners at the Gotham Awards included Casey Affleck, who won best actor for his role in Kenneth Lonergan's Manchester by the Sea, while Isabelle Huppert was named best actress for her performance in Paul Verhoeven's Elle, beating the likes of Natalie Portman for Jackie and Annette Bening for 20th Century Women.
French actress Huppert joked: "I feel so American tonight. I feel good. I feel really good."
In reference to the recent US election, Oliver Stone, who was given a tribute award along with Amy Adams, Ethan Hawke and producer Arnon Milchan, said: "You can be critical of your government. We've forgotten that."
The Gothams are not historically a reliable Academy Awards predictor.
But their last two big winners, Spotlight and Birdman, did go on to triumph at the Oscars.

A drug that destroys the characteristic protein plaques that build up in the brains of patients with Alzheimer's is showing "tantalising" promise, scientists say.

Experts are cautious because the drug, aducanumab, is still in the early stages of development.
But a study in Nature has shown it is safe and hinted that it halts memory decline.
Larger studies are now under way to fully evaluate the drug's effects.
The build-up of amyloid in the brain has been a treatment target for many years.
This study, of 165 patients, was designed to test aducanumab was safe to take.
After a year of treatment, it also showed the higher the dose the stronger the effect on amyloid plaques.
The researchers then carried out tests on memory and found "positive effects".
However, 40 people dropped out of the study, half because of side effects they experienced, such as headaches. These too were much more common with a higher dosage.
The next phase of research - phase 3 - involves two separate studies. These are recruiting 2,700 patients with very early stage Alzheimer's across North America, Europe and Asia in order to fully test the drug's effect on cognitive decline.
Dr Alfred Sandrock of the biotech company Biogen, which worked with the University of Zurich on the research, said:  "Phase 3 really needs to be done and I hope it will confirm what we have seen in this study.
"One day I could envisage treating people who have no symptoms because if you have amyloid in the brain it's likely you'll develop Alzheimer's one day."
However, there have been many disappointments in Alzheimer's drug development, and it is over a decade since the last drug for people with the condition was licensed.
Other experts have welcomed this latest research - but with caution.
Dr David Reynolds, chief scientific officer at Alzheimer's Research UK, said the results provided "tantalising evidence that a new class of drug to treat the disease may be on the horizon".
And Dr James Pickett, head of research at the Alzheimer's Society, added: "What is most compelling is that more amyloid was cleared when people took higher doses of the drug.
"No existing treatments for Alzheimer's directly interfere with the disease process and so a drug that actually slows the progress of the disease by clearing amyloid would be a significant step."
However, Dr Tara Spires-Jones, of the Centre for Cognitive and Neural Systems at the University of Edinburgh, said: "I am cautiously optimistic about this treatment, but trying not to get too excited because many drugs make it through this early stage of testing then go on to fail in larger trials."
And John Hardy, professor of neuroscience at University College London, said: "These new data are tantalising but they are not yet definitive."


Glamorgan bowling coach Robert Croft believes scrapping the toss in County Championship Division Two matches could benefit the game.

The England and Wales Cricket Board will discuss the plan on Thursday and it could come into effect in 2016.
Former England Test spinner Croft believes it could mean better pitches.
"I guess what they're trying to do is produce pitches that are capable of developing all round skills in the game," said Croft.
If the plan is approved, a one-year trial will take place in 2016 to try to improve pitches and encourage spin bowlers.
The away team would choose whether to bat, bowl or still have a toss if the pitch condition was uncertain.
The ECB believes many matches in Division Two are decided by the toss because home teams are producing pitches to suit their bowlers.
However, no team in the County Championship has been deducted points for preparing a poor pitch since 2011.
"This is borne out of pitches in recent times being far too bowler friendly and games being over very quickly indeed," added Croft, who took more than 1,000 wickets during his playing career with Glamorgan.
"They want pitches that are not just seam bowler friendly but batsman friendly and spin friendly, so I guess it's trying to even the balance of pitches throughout the game in this country to hopefully benefit all the skills which will hopefully benefit the national team.
"It's a move we have to be open minded about - the toss has been there pretty much since the game started so it's very easy to get closed minded about it and say we can't mess with tradition.
"But the development of the game is bigger than the toss.
"And also we have to think of the supporters. They expect to see a good game of cricket that finishes about tea time on the last day ideally, but a lot of the games now are over in two days or just barely into the third day."


Four Irish citizens, who were among hundreds of people besieged in a Cairo mosque surrounded by Egyptian security forces, have now left the mosque.

They were taken by Egyptian security forces to an area away from the mosque.
A spokesperson for the Irish Department of Foreign Affairs said the four siblings are expected to be released later on Saturday.
Their father is Hussein Halawa, the imam of Ireland's largest mosque in Clonskeagh in Dublin.
Sisters Omaima Halawa, 21, Somaia, 27, and Fatima, 23, and their brother Ibrihim, 17, were in the al-Fath Mosque in Cairo's Ramses area along with hundreds of protesters.
All the supporters of ousted President Mohammed Morsi have now been taken out of the mosque, and many have been arrested, security forces said.
The confrontation at the mosque continued for most of the day - with exchanges of gunfire between security forces and protesters.
Speaking to RTÃ‰ News on Saturday morning, Omaima Halawa said the mosque was surrounded.
She said people inside were told by security forces that anyone who attempted to leave the building would be shot.
The final-year student at Blanchardstown Institute of Technology told the Irish state broadcaster the scene was very frightening.
"We are surrounded in the mosque, inside and outside. There is a little hallway that the police forces have entered, have broken in and surrounded us. A few minutes ago they broke in. They threw tear gas at us."
She added that the Irish Embassy had been in contact by phone.
The Halawa siblings travelled to Egypt at the beginning of the summer for a holiday.
Their mother Amina Mostafa travelled with her children while their father remained in Dublin.
Speaking to RTÃ‰ from their home in Firhouse in Dublin, another sister Nasaybi said it was an extremely difficult situation for the family.
"We are really worried. We don't know how to help them," she said.
"All what we can do is try to support them by calling and give them some hope that this will end and they will come home safely."
The Halawa family moved to Ireland about 18 years ago.
A spokesman for the Department of Foreign Affairs said embassy staff had been in contact with the group and were working closely with the authorities in Cairo.
The stand-off began overnight, when the al-Fath mosque - which was being used as a makeshift clinic for the injured and morgue for some of the 80 dead from clashes on Friday - turned instead into what correspondents describe as a fortress.
Muslim Brotherhood members barricaded themselves inside, using anything at their disposal.
It turned into a scene of chaos. Tear gas was fired into the building, and witnesses saw live ammunition fired by both sides.
Egypt is in turmoil after protest camps in Cairo were cleared on Wednesday with the loss of hundreds of lives.
The Brotherhood, which backs deposed President Mohammed Morsi, has called for a week of daily rallies.


The UN human rights chief has accused the Saudi-led coalition of causing twice as many civilian casualties as all the other forces fighting in Yemen.

Zeid Raad Al Hussein condemned "the repeated failure" of the coalition to prevent deadly incidents.
He said air strikes had caused almost all the coalition's civilian casualties.
More than 6,000 people, about half of them civilians, have been killed since Saudi Arabia launched a multi-national campaign against rebels in March 2015.
Saudi Arabia has denied causing large-scale civilian deaths, saying it is making every effort to avoid hitting civilian targets.
Mr Hussein's comments come three days after some 106 civilians were killed in what medics and witnesses said was an air strike on a market in Mastaba, north-west Yemen, in one of the deadliest incidents of the war.
The UN said staff who had visited the scene of the attack said, apart from a check-point about 250 metres (820 ft) away, there was no evidence it was a military target.
"Looking at the figures, it would seem that the coalition is responsible for twice as many civilian casualties as all other forces put together, virtually all as a result of air strikes," Mr Hussein said.
"They have hit markets, hospitals, clinics, schools, factories, wedding parties - and hundreds of private residences in villages, towns and cities including the capital, Sanaa."
"Despite plenty of international demarches, these awful incidents continue to occur with unacceptable regularity."
Saudi Arabia said it was investigating the attack on Mastaba, adding its forces had targeted a "gathering area" for Houthi rebel fighters about six miles (10km) away.
Zeid Raad Al Hussein however said coalition forces appeared not to have taken proper steps to distinguish between military and civilian targets, adding both they and the rebels might have committed "international crimes".
On Wednesday, Saudi Arabia's chief military spokesman, Brig Gen Ahmad al-Assiri, said the military campaign was "in the end of the major combat phase".
The coalition launched its offensive last March with the aim of repelling the rebels and restoring exiled President Abdrabbuh Mansour Hadi to power.


Carbon monoxide alarms have become a legal requirement in all new homes in Northern Ireland.

The new law comes as research suggests half of the UK population mistakenly believe their household smoke alarms will alert them to the gas.
The law follows the deaths of two teenagers from carbon monoxide poisoning  in August 2010.
Neil McFerran and Aaron Davidson died after a gas leak in a holiday apartment in Castlerock, County Londonderry.
The two young men, who were 18 years old, had been staying at the apartment near Coleraine with a third friend, Matthew Gaw, who survived. The three friends were found by relatives.
Their families have welcomed the news but said it only reaches about 5% of properties. They have called for more to be done.
"I think it's a great forward step, but this is only going to be new buildings, they still could go further," Aaron Davidson's mother Katrina said.
"We still need to push awareness of carbon monoxide, that it is a killer."
The new law also requires that an alarm be fitted whenever a boiler or solid fuel stove is upgraded or replaced.
A survey carried out by the Carbon Monoxide - Be Alarmed! campaign states that only 39% of people have a carbon monoxide alarm.
It also suggests that half of the UK population mistakenly believed their smoke alarm would alert them to carbon monoxide gas.
The research was carried out in September among 3,458 UK adults. It said 81% of those surveyed know that carbon monoxide can kill.
Carbon Monoxide - Be Alarmed! is the national campaign to reduce the number of deaths and injuries caused by carbon monoxide.
The campaign is run by Energy UK on behalf of Britain's six major gas and electricity companies, in partnership with the Dominic Rodgers Trust.
From 31 October, Northern Ireland Building Regulations will require a carbon monoxide detector or alarm "in the room where the appliance is located. However, if the combustion appliance is installed in a room or space not normally used e.g. a boiler room/cupboard, the detector/alarm should be located just outside the room or space".
The research findings also included:
Carbon monoxide is produced when fuels such as gas, oil, charcoal, coal and wood do not burn completely.
The most common cause of this is when an appliance, such as a boiler or cooker, is installed incorrectly or poorly maintained. Carbon monoxide can also build up when flues, chimneys or vents are blocked.
The Department of Health estimates that 50 people are killed by carbon monoxide poisoning, and at least 4,000 are treated in hospital, in the UK each year.
However, the Carbon Monoxide - Be Alarmed! group says that figure is likely to be much higher, as carbon monoxide poisoning is very difficult to diagnose because symptoms are often similar to common illnesses like flu and food poisoning.
Meanwhile, safety checks carried out by the fire service in more than 22,000 homes across Merseyside in England found that fewer than one in 10 had a carbon monoxide alarm.


University groups are warning that tighter visa rules, claimed to be under consideration by the Home Office, would cut overseas student numbers by 15%.

The proposals are believed to include tougher English language requirements for students.
Dominic Scott, head of the UK Council for International Student Affairs, said it would be a "nail in the coffin" for recruiting overseas students.
The Home Office has argued there are no limits on numbers of genuine students.
Universities have already been lobbying ministers to remove overseas students from migration targets - but the new English language proposals, if they were given the go-ahead, would mean even an higher threshold for entry.
Universities argue that overseas students are increasingly important to the UK economy and that raising more barriers sends out a negative message in this competitive global market.
Universities UK says overseas students are worth Â£7bn to the UK each year.
Mr Scott, head of the advisory body on international students, described the revised language requirements as "pretty extreme".
He warned that if implemented they would have a "massively damaging effect" on universities wanting to recruit overseas students, preventing about 15% of the current intake from gaining visas.
Mr Scott said universities of all kinds saw the proposals as a "major concern" and would be asking for evidence there was a problem with students with poor language skills.
He said the tougher language rules could make it difficult to recruit for pre-degree courses and science and maths subjects, where students might have very advanced skills but weaker English language ability.
The move by the Home Office follows a speech on controlling immigration by Prime Minister David Cameron in May.
"We must go further on curbing abuse, shutting more bogus colleges, being more robust with institutions that have high rates of students overstaying and looking to toughen English language requirements for students," he said.
Mr Cameron said tighter control of migration would not "stop us from rolling out the red carpet for the brightest and the best: the talented workers and brilliant students who are going to help Britain succeed".
"As I've said before, no cap on the number of overseas students who come and study at our universities," said the prime minister.
The university sector has been campaigning for overseas students not to be part of this drive to reduce migrant numbers.
A recent report from the Parthenon consultancy group said a potential extra 80,000 jobs over the next four years were being lost because of the current regulations on overseas students.
For every overseas student in the UK, the equivalent of 0.6 of a job was created, driven by spending such as fees, accommodation, travel and entertainment.


Shares of Twitter fell in after-hours trading as the company's quarterly results showed user growth faltering.

Twitter reported a net loss of $90m (Â£62m) for the last three months of 2015 versus a loss of $125m a year ago.
The social media site saw its user growth stall, with 320 million average monthly active users - the same number as the previous quarter.
This is the first quarter in Twitter's history that the number of monthly active users has not grown.
Revenue for the quarter rose by 48% to $710m compared to the fourth quarter of 2014, matching analysts' expectations.
Immediately after the results were announced, Twitter shares fell 10% in after-hours trading, before recovering to a 3% loss.
"With no increase in new users, but otherwise good financial performance, Twitter hasn't yet shown how it can rise from the troubling spot of not being able to grow the business," said Brian Blau, research director at Gartner.
Analysis: Dave Lee, BBC North America Technology Reporter, San Francisco
If you discount SMS-only users - who don't really count - Twitter lost two million users in its last quarter.
Unprecedented, and unacceptable for investors.
Despite new features, advertising campaigns and the constant publicity activity Twitter enjoys, it didn't grow a jot.
Now, Twitter called it a seasonal lull, and is confident it's made up lost ground in the current quarter.
But that won't cut it.
Big changes are needed, but the remaining 307 million active users may not like it. Perhaps it's time to ignore users and just get to work.
Whether it's types of retweets, or hearts instead of stars, Twitter users en masse say "no no no".

Rival social media sites have seen their user bases grow. Facebook has 1.5 billion users and Instagram has 400 million, despite launching four years after Twitter
In its results, Twitter said its user base increased in January.
Investors were also disappointed in Twitter's revenue forecast for the first quarter of 2016. The company projected revenue for the first quarter ranging between $595m and $610m, well below analysts' estimates of $627m.
Investors had been anticipating the announcement of major changes to Twitter's product offerings to increase the user base.
The company announced earlier on Wednesday that it would be introducing a new feature that shows the best tweets at the top of a user's feed, rather than showing tweets in reverse chronological order.
Some users felt the change would kill the social network and began to use the hash tag #RIPtwitter in protest.
The company said it was planning on improving its video offerings, building on the launch of its live video streaming product, Periscope, in March.
Twitter shares have more than halved since its chief executive Jack Dorsey - one of the site's founders - returned to Twitter in July.
The company has never reported a quarterly profit.


Adam Murray has resigned as Mansfield Town manager after two years in charge.

The Stags lie 18th in League Two with one win in 11 games, and lost 4-0 at Portsmouth on Saturday.
"I have been with the club for over 14 years and having discussed it with my management team we have decided it is time for a change," the ex-player said.
Under-21s head coach Mike Whitlow and youth team manager John Dempster will take temporary charge with Mansfield set to host Crawley on Saturday.
First-team coaches Karl Hawley and Richard Cooper have also left Field Mill.
Murray had pledged his future to the club 11 days ago after reports he would quit.
Chairman John Radford said: "I've worked with Adam for a long time and respect him immensely. The decision by Adam to part ways was made with a very heavy heart.
"Adam will always be in Mansfield Town's hall of fame. He has served the club magnificently as both a player and for almost two years, a manager, and I sincerely wish him well for the future."
Murray was placed in caretaker charge - with the Stags sitting 19th in League Two - following the departure of Paul Cox in November 2014 and his appointment was made permanent a month later.
He helped the Stags avoid relegation and last season he led them to a 12th-placed finish, 11 points adrift of the play-off places.

There were angry scenes in Israel's parliament on Wednesday as preliminary approval was given to a bill that would restrict the use of outdoor loudspeakers by religious institutions.

Two versions of the so-called "muezzin bill", which would mostly affect Muslim calls to prayer, passed their first readings by slim majorities.
Some Arab MPs ripped apart copies of the legislation during a debate.
The bill will have to go through further readings before becoming law.
One version of the bill would ban all places of worship from using loudspeakers between 23:00 and 07:00. The other would prohibit the use of speakers considered "unreasonably loud and likely to cause disturbance" at any time of day.
They are amendments of a draft approved by Prime Minister Benjamin Netanyahu's cabinet in November.
Mr Netanyahu said at the time that he had received numerous complaints from all parts of Israeli society "about the noise and suffering caused them by the excessive noise coming to them from the public address systems of houses of prayer".
One of the bill's sponsors, Motti Yogev of the Jewish Home party, said on Wednesday that it was "first and foremost a piece of social legislation which will allow people to relax during rest hours, Arabs and Jews alike".
"There is no wish to hurt the believers of any faith," he added.
The bill's critics say it as an attack on religious freedom.
"The voice of a muezzin has never caused any environmental noise. It is about an important Islamic religious ritual, and we have never in this house intervened in any religious ceremony related to Judaism. Your action is a racist slur," warned Ahmed Tibi of the Arab-dominated Joint List alliance during the debate.
"Your intervention strikes at the very souls of Muslims," he added.
Ayman Odeh, the leader of the Joint List, was thrown out of the chamber after tearing up a copy of the bill.
Arab citizens of Israel, also known as Israeli Arabs, are descendants of the 160,000 Palestinians who remained after the State of Israel was created in 1948. They make up about 20% the Israeli population.
About 80% of Israeli Arabs are Muslim; the rest are divided, roughly equally, between Christians and Druze.


The 2016 Nobel Prize in Physics has been awarded to three British-born scientists for discoveries about strange forms of matter.

David Thouless, Duncan Haldane and Michael Kosterlitz will share the 8m kronor (Â£727,000) prize.
Their work could result in improved materials for electronics and is already informing one approach to super-fast computing.
They were named at a press conference in Sweden.
The winners join a prestigious list of 200 other Physics laureates recognised since 1901.
The Nobel Committee said the trio's discoveries had "opened the door on an unknown world".
When matter is in extreme conditions, such as when it's very cold or flat, scientists start to see unusual behaviour from the atoms.
These phenomena complement the familiar phases of matter, namely when things change from solid to liquid to gas.
Prof Haldane commented: "I was very surprised and very gratified."
"The work was a long time ago but it's only now that a lot of tremendous new discoveries are based on this original work, and have extended it."
All three researchers used maths to explain strange physical effects in rare states of matter, such as superconductors, superfluids and thin magnetic films.
Kosterlitz and Thouless focused on phenomena that arise in flat forms of matter - on surfaces or inside extremely thin layers that can be considered two-dimensional.
This contrasts with the three dimensions (length, width and height) with which we usually describe reality.
Haldane also studied matter that forms threads so thin they can be considered one-dimensional.
Much of the work involves a field of maths known as topology, which describes properties of matter at large and small scales.
Acting chairman of the Nobel committee, Prof Nils MÃ¥rtensson, commented: "Today's advanced technology - take for instance our computers - relies on our ability to understand and control the properties of the materials involved.
"And this year's Nobel laureates in their theoretical work discovered a set of totally unexpected regularities in the behaviour of matter, which can be described in terms of an established mathematical concept - namely, that of topology.
"This has paved the way for designing new materials with novel properties and there is great hope that this will be important for many future technologies."
Phase transitions occur when matter changes from one phase to another, such as when ice melts and becomes water
Kosterlitz and Thouless described a type of phase transition in a thin layer of very cold matter
In the cold, vortices form (diagram) as tight pairs, but at higher temperatures, as the phase transition occurs, they separate and "sail" off in different directions
One aspect of the work, known as the Quantum Hall effect, has led to a real-world application.
Prof Nigel Cooper, from the University of Cambridge, told BBC News: "The Quantum Hall effect is used in metrology to give a precise definition of the Ohm in resistance.
Just as a kilogram or a metre requires an exact definition, the maths behind today's Nobel prize has helped precisely describe the unit of electrical resistance - how a device or material reduces the electrical conductance flowing through it.
As an application, he said, "it's not in your iPhone, but it's used in government labs around the world."
"There are many aspects of topology people point to that could be relevant in future, but these are not things that are working today."
For instance, Prof Cooper explained, scientists are exploring whether topological concepts could be used in "robust quantum devices which can do things that classical computers or classical circuit elements are unable to do".
Microsoft's Station Q project is taking just such an approach to the development of powerful quantum computers.
"The topological aspects can give the quantum information a robustness against being destroyed by the usual noisy environment," said Prof Cooper.
In addition, he said, topological metals could be used in the manufacture of improved conductors or transistors.
2015 - Takaaki Kajita and Arthur McDonald were awarded the prize the discovery that neutrinos switch between different "flavours".
2014 - Isamu Akasaki, Hiroshi Amano and Shuji Nakamura won the physics Nobel for developing the first blue light-emitting diodes (LEDs).
2013 - Francois Englert and Peter Higgs shared the spoils for formulating the theory of the Higgs boson particle.
2012 - Serge Haroche and David J Wineland were awarded the prize for their work with light and matter.
2011 - The discovery that the expansion of the Universe was accelerating earned Saul Perlmutter, Brian P Schmidt and Adam Riess the physics prize.
2010 - Andre Geim and Konstantin Novoselov were awarded the prize for their discovery of the "wonder material" graphene.
2009 - Charles Kuen Kao won the physics Nobel for helping to develop fibre optic cables.
Although British in origin, the three individuals all now live and work in the US.
David Thouless was born in 1934 in Bearsden. He is an emeritus professor at the University of Washington.
Duncan Haldane was born in 1951 in London. He is a professor of physics at Princeton University.
Michael Kosterlitz was born in 1942 in Aberdeen. He is currently affiliated to Brown University.

Wigan Athletic booked their place in the second round of the EFL Cup - but Blackpool will wonder how they slipped to defeat at the DW Stadium.

Despite dominating the first half, the Seasiders somehow found themselves trailing 2-0 at the break.
Josh Laurent marked his first Wigan start with the opening goal on 17 minutes. and Jordan Flores - who spent the second half of last term on loan at Bloomfield Road - doubled the advantage on the stroke of half-time.
Armand Gnanduillet pulled one back with a header from a corner just before the hour mark.
But substitute Jamille Matt squandered three gilt-edged opportunities inside the final quarter to take the game to extra-time.
After firing wide from a good position, the lively forward then saw a flick header glance the bar on the way over.
But arguably the best chance came deep in stoppage time, when Matt ignored the supporting Nathan Delfouneso to go it alone, only to drag his shot wide of Owen Evans' far post.
