The UK's party leaders clashed on a range of issues including the NHS, immigration and the deficit in the first TV election debate.

It is the only time Ed Miliband and David Cameron will appear together on TV ahead of 7 May's polling day.
The Labour and Tory leaders debated zero hours contracts and spending cuts in the ITV-hosted contest.
But some of the sharpest exchanges in the two hour event came when Lib Dem Nick Clegg clashed with Mr Cameron.
Snap polls taken after the debate gave a mixed verdict.
A YouGov poll of 1,100 people gave a clear victory to the SNP leader Nicola Sturgeon, with 28%, followed by UKIP leader Nigel Farage on 20%, Mr Cameron on 18%, Mr Miliband on 15%, Mr Clegg on 10%, Green Party leader Natalie Bennett on 5% and Plaid Cymru's Leanne Wood on 4%.
But a ComRes poll for ITV made it a dead-heat between Mr Cameron, Mr Miliband, Mr Farage and Ms Sturgeon, although Mr Cameron came out on top on the question of who was most capable of leading the country.
Mr Miliband was judged best performer in an ICM poll for the Guardian, taking 25% of support, just ahead of David Cameron on 24%.
Analysis by BBC Political Editor Nick Robinson
There was no game changer. No single "moment", no zinger, no gaffe which looks set to re-shape the course of this election. Save perhaps for one.
That was the presence on the stage of not two or three party leaders but seven - a debate in which the talk of a new sort of politics, multi-party politics, became visible reality.
If that gives a boost for UKIP's Nigel Farage with his laser focus on immigration and his attack on the "Westminster parties" - as the early instant polls suggest - it will worry the Tories.
If it also promotes Natalie Bennett's Greens, Nicola Sturgeon's SNP and Leanne Wood's Plaid Cymru after their assault on austerity - it will frighten Labour. The consequence could be an outcome more unpredictable and more uncertain than any election for years.
Read Nick's full blog here.
In some of the testiest exchanges, Mr Clegg accused Mr Cameron of wanting to cut the money going into schools - Mr Cameron denied this and accused the Lib Dem leader of taking a "pick and mix approach" to decisions they had made together in cabinet.
Ed Miliband attacked Mr Clegg for "betraying young people" over tuition fees - a clearly riled Mr Clegg attacked the Labour leader's "pious stance" and challenged Mr Miliband to apologise to the British public for "crashing the economy". Mr Miliband said Labour had admitted getting it wrong over bank regulation.
Nicola Sturgeon took a firm line against austerity and signalled areas, such as increasing the top rate of income tax, where she could work with Labour but said getting more SNP MPs elected to Westminster was needed to "keep them honest".
Plaid Cymru leader Leanne Wood and the Green Party's Natalie Bennett joined Ms Sturgeon in stressing their anti-austerity credentials.
The verdict of the snap opinion polls
UKIP leader Nigel Farage risked controversy by highlighting the number of foreign nationals with HIV who he said were treated by the NHS, saying: "We have to look after our own people first."
Plaid Cymru's Leanne Wood said Mr Farage "ought to be ashamed of himself" for deploying "scaremongering rhetoric".
Mr Farage also clashed directly with David Cameron on the issue of immigration, saying he stood no chance of getting agreement from other EU leaders to restrict the free movement of people.
Mr Cameron rejected this and accused Mr Farage of wanting to get a Labour government through the "back door".
He said: "We do need immigration that's controlled and fair. In recent decades it's been too high and I want to see it come down."
Mr Farage responded: "As members of the EU, what can we do to control immigration? Let me tell you - nothing."
It was a relatively even-tempered debate, with few examples of the leaders shouting across each other, but a woman from the audience attempted to disrupt proceedings, shouting "they are not listening to us" as Mr Cameron gave an answer on the armed forces.
The heckler, Victoria Prosser, 33, from Salford, told reporters she challenged David Cameron because she wanted people to question "the 1% at the top" who she said were not working in the country's interests.
Mr Miliband repeatedly described what he would do "if I am prime minister", in raising the minimum wage, banning exploitative zero-hours contracts and "rescuing our NHS".
Mr Clegg directly challenged Mr Cameron over his decision not to ask the richest to pay more towards deficit reduction, but instead to impose "ideologically-driven cuts".
Responding to Mr Cameron's casting of the election as a choice between "competence and chaos", the Lib Dem leader urged him to "imagine the chaos in people's lives" caused by cuts in spending on health, schools and childcare.
Mr Cameron said the wealthy would be the target of a Â£5bn crackdown on tax avoidance and evasion.
He then turned the spotlight on Mr Miliband, who he said "still thinks the last Labour government didn't tax too much, borrow too much and spend too much".
Green Party leader Natalie Bennett got things under way with an anti-austerity message, saying there was an "alternative" to making the poor and disadvantaged pay for the mistakes of bankers.
Nigel Farage said the other six parties were all the same because they supported EU membership, adding he wanted to "take back control of our borders".
Lib Dem leader Nick Clegg said no one would win the election and voters should think about who they want to see in coalition, saying his party offered "grit" in government.
Nicola Sturgeon had a message of "friendship" for the rest of the UK, saying the SNP will work with other "parties of like mind" to end the "bedroom tax" and protect the NHS.
Ed Miliband said Labour had a better plan for the country and vowed to ban exploitative "zero hours" contracts and "save" the NHS.
David Cameron said the Conservatives' economic plan was working, adding: "Let's not go back to square one, Britain can do so much better than that."
Plaid Cymru's Leanne Wood had an anti-austerity message and said her party can "win for Wales" in a hung Parliament.
Campaigning was quieter than usual on Thursday, as most of the party leaders spent the afternoon preparing for the TV clash.
The seven-way debate emerged from tortuous negotiations between the parties and the broadcasters, with David Cameron refusing a direct head-to-head with Ed Miliband.
A question and answer programme featuring David Cameron and Ed Miliband appearing separately, was hosted by Channel 4 and Sky News last week, and a BBC debate involving opposition party leaders, moderated by David Dimbleby on 16 April.
There will also be a special Question Time on BBC One, a week before polling day, with Mr Cameron, Mr Miliband and Lib Dem leader Nick Clegg appearing one after the other to answer questions from a studio audience.
The Democratic Unionist Party, which has eight MPs, has criticised its exclusion from the programme.

Hundreds of social media photos capturing hidden sights of Birmingham have gone on display to celebrate a landmark year in the city.

The exhibition features pictures of the city posted on photo-sharing site Instagram and is the first display of its kind at the Ikon Gallery.
Themes include architectural heritage, hidden spaces, urban street art, evolving landscape, art and culture.
The More Birmingham Instagram Showcase runs until Sunday.
The exhibition celebrates a successful series of 'Instameet' social media events that have taken place throughout 2015.
The events captured key milestones, from the opening of the revamped New Street Station to the redevelopment of Paradise Circus, key cultural celebrations such as the Big Hoot and the Birmingham Weekender.
The thousands of images produced have generated more than one million hits across social media throughout the year.
Emma Gray, director of marketing and communications at Visit Birmingham, said: "Birmingham's Instameet events have created an online photographic legacy, with thousands of remarkable images generated and shared amongst potential visitors across the world."
The exhibition comprises a mixture of print and projected photography, complimented by a virtual gallery accessible online.


Oxford's Magdalen Bridge will be open to the public during the city's traditional May Day celebrations for the first time in six years.

The bridge has been closed on May Day morning since 2005 after 40 people were injured jumping into the river.
Traditionally, thousands of people gather on and around Magdalen Bridge to hear choristers sing hymns at dawn from the tower at Magdalen College.
The city and county councils and police have worked to "ensure a safe" event.
Last year, about 30 revellers ignored safety warnings and broke through barriers to jump from the bridge.
The water is shallow and the county council said the cost to the health service in 2005 was about Â£50,000.
Police urged people not to "abuse" the decision to allow pedestrians access this year.
Many other events will take place across the city, including morris men dancing in Radcliffe Square, Catte Street and Broad Street.
Oxford City Council and the county's cultural development agency, Oxford Inspires, are both working with an event producer responsible for other big occasions in the city.
The leader of Oxford City Council, Councillor Bob Price, said: "We have been working closely with the police and Oxfordshire County Council to ensure a safe and enjoyable event with Magdalen Bridge open, as it has traditionally been, and we are delighted that this collaboration has had a successful outcome."
Oxford commander, Supt Amanda Pearson, said: "Thames Valley Police supports the decision taken by the council to reopen Magdalen Bridge to the public for this year's May Morning celebrations, and will work closely with our partners to ensure this is done in a safe way.
"I would urge people to recognise this decision is one that has been made to further their enjoyment of this unique celebration, and not to abuse it."


Japan has said that its Antarctic whaling fleet will sail on 1 December, despite a UN legal decision that its "research ships" are actually commercial hunts.

A statement on Japan's Fisheries Agency website said whaling will run from late December until March next year.
Japan stopped whaling for one year, but announced last week it would resume.
For years the activity has pitted Japan against activists who call it inhumane and unsustainable.
In 2014, the International Court of Justice (ICJ) ruled that Japan's whaling programme did not qualify as scientific and should cease.
That season Japan sent whaling ships to the ocean, but, respecting the verdict, returned with no catch.
The Japanese government says its new whaling programme takes into account that ICJ decision and is now much smaller.
The hunt will aim to capture 333 Antarctic minke whales, about one-third of what it used to kill.
It will also conduct non-lethal research, including sighting surveys and the collection of biopsy samples.
Four ships will be involved in the hunt, including the 8,000 tonne mother ship, the Nisshin Maru.
Japan's earlier announcement that it would resume whaling was met with dismay by environmental activists and governments opposed to the hunt.
"We do not accept in any way, shape or form the concept of killing whales for so-called 'scientific research'," said Australian Environment Minister Greg Hunt.
In 1982, the International Whaling Commission (IWC), the global body that regulates whaling, agreed a pause - often referred to as a moratorium - on commercial whaling from the 1985/1986 season.
Japan agreed to the moratorium, but has used the scientific whaling exemption to continue.
Objection: A country formally objects to the International Whaling Commission moratorium, declaring itself exempt. Example: Norway
Scientific:  A nation issues unilateral "scientific permits"; any IWC member can do this. Example: Japan
Indigenous (aka Aboriginal subsistence): IWC grants permits to indigenous groups for subsistence food. Example: Alaskan Inupiat
Guide to the great whales
Pointing to the IWC's remit to regulate rather than eliminate the whaling industry, Japan insists its practices are sustainable and that animal rights concerns are both sentimental and irrelevant.
Japan makes no secret of the fact that much of the whale meat produced as a result of what it insists is scientific research, ends up in supermarkets and restaurants.
While sale of by-products from genuine scientific whaling research is permitted, opponents say the scale of the sales dwarfs the amount of useful scientific evidence gathered, which they also insist can be found through non-lethal research.
Whale products are not frequently eaten by most people in Japan, some of whom share others' discomfort with the practice of whaling. But many other Japanese also feel it is an important cultural tradition and object to being pressured to give it up.


Asian markets have risen, following gains on Wall Street, after the US Federal Reserve unveiled its latest stimulus plan.

The US central bank said it would buy $40bn (Â£25bn) of mortgage debt a month and kept interest rates at below 0.25%.
It said it would also continue its programme to reduce long-term borrowing costs for firms and households.
Japan's Nikkei 225 index rose 1.8%, South Korea's Kospi gained 2.9% and Hong Kong's Hang Seng closed up 2.9%.
This followed gains of 1.6% rise in the Dow Jones and S&P 500 indexes on Thursday.
Investors are hoping the measures will revive growth in the US economy, the world's biggest, and a key market for Asian exports.
"They're saying that the punch bowl, the fuel for the economy, isn't going away - it's going to be here as long as you need it," said Tony Fratto, managing partner at Hamilton Place Strategies, a policy consulting firm.
There have been growing fears about the global economy with a weak recovery in the US and the ongoing debt crisis in the eurozone.
The slowdown in China's economy, the world's second-largest, and one of its biggest drivers of growth after the global financial crisis, has fanned those fears.
Prompted by these concerns, policymakers in these regions have been taking measures to try to spur a fresh wave of growth.
The Federal Reserve's announcement came days after the European Central Bank (ECB) announced its latest plan.
Last week, the ECB said that it would buy bonds from the bloc's debt-ridden nations in an attempt to bring down their borrowing costs.
Meanwhile, China has cut its interest rates twice since June to bring down borrowing costs for businesses and consumers. Beijing has also lowered the amount of money that banks need to keep in reserve three times in the past few months to further encourage lending.
This week South Korea has also unveiled two stimulus measures aimed at boosting domestic demand and helping small businesses.
Analysts said the moves had helped reassure investors and markets that policymakers were doing all they could to ensure growth in the global economy.
"You're witnessing global economic stimulus across the board," said Quincy Krosby, a market strategist at Prudential Financial.
"The Fed's actions are occurring in conjunction with the European Central Bank's commitments to support the euro and amid talk that China could also deliver a stimulus package."


The fossil of a tiny bird that lived 62 million years ago confirms that birds evolved very rapidly after the asteroid strike that wiped out the dinosaurs.

The sparrow-sized tree-dweller lived ''just a geological blink of an eye" after the mass extinction.
Bird fossils from that time period are very rare.
Analysis suggests the ancestors of most modern birds, from owls to woodpeckers, had taken to the wing within four million years of the asteroid strike.
Like mammals, the birds that survived the extinction were able to expand and diversify to become one of the most successful animal groups on Earth.
Analysis of the fossil and its relationship to other members of the bird family tree suggests as many as 10 major bird groups had appeared within four million years of the extinction.
Dr Daniel Ksepka, curator of science at Bruce Museum in Greenwich, Connecticut, said Tsidiiyazhi abini  was a very special little bird for several reasons.
''It is very old, very small, and had zany little feet,'' he explained.
''The age is between 62.2 and 62.5 million years, just a geological blink of the eye after the asteroid impact that wiped out the dinosaurs.''
DNA evidence suggests birds recovered rapidly from the extinction event 66 million years ago that wiped out most animals on land, including flying reptiles, dinosaurs and primitive birds.
The origins of modern birds can be traced back to this time. However, bird fossils from this era in geological history are very rare because their bones are so small and delicate.
This has made it difficult to resolve how modern birds arose and diversified, leading to some controversy. The discovery of Tsidiiyazhi abini, an ancient species of mousebird, is a new source of evidence.
''When we place the bird in the evolutionary tree, it reveals that other closely related groups must have also split off by then because they occupy lower branches,'' Dr Ksepka told the BBC.
''So this discovery shows not only mousebirds but things like owls, raptors, the Coraciimorphae (a group that includes birds like kingfishers and woodpeckers) and many other groups were all showing up just a short time after the asteroid impact that wiped out the dinosaurs.''
Tsidiiyazhi abini,  or ''little morning bird'' was found in 62.5-million-year-old rocks in the Nacimiento Formation of New Mexico.
Dr Thomas Williamson was on a fossil hunting trip with his twin sons, when the birds' bones came to light.
''They discovered an unusually rich site that had some skeletons of small mammals,'' the curator of Palaeontology at the New Mexico Museum of Natural History and Science explained.
''Over the next several months, I collected some bulk samples from the site and within these I discovered the bones of a small bird.''
He said the new birds were close to modern mousebirds (Coliiformes), a group now found only in Africa, but which was geographically more widespread in the Palaeogene [from 66 million years ago to 23 million years ago].
The bird was able to flip the fourth toe on its foot to face backwards - something that is useful for climbing and grasping. This feature is also seen in other birds, such as modern owls.
Tsidiiyazhi lived at a time when the planet was undergoing great change, with placental mammals and flowering plants also diversifying rapidly.
The bird lived in forests and dined on fruits and seeds from flowering plants.
Today, there are more than 10,000 living species of bird.
The research is published in the journal PNAS.

The number of complaints about so-called packaged bank accounts has "shot up", according to the Financial Ombudsman.

Some 25,500 people complained about the issue in the first six months of 2015, more than in the whole of 2014.
Packaged bank accounts offer additional benefits such as insurance and cheaper overdrafts, in return for a fee.
But many customers complained that they were sold the accounts unwittingly or they did not need the insurance.
While the number of complaints about Payment Protection Insurance (PPI) is now falling, the Ombudsman is now seeing about 1,000 complaints about packaged accounts every week.
In 2014 there were 21,348 such complaints, and just 5,667 in 2013.
Last month, Barclays set aside £250m to compensate customers who might have been mis-sold the accounts.
Packaged bank accounts are often marketed as "gold" or "premium" - and customers typically pay between £5 and £25 a month.
All the major banks and building societies have offered them over the years, in an attempt to increase their income.
Complaints fall into three categories:
"Pushy sales tactics have left many consumers paying a monthly bill for benefits that aren't suitable, and don't give them good value for money," said Hannah Maundrell, editor in chief of the comparison site money.co.uk.
She estimates that the average fee on such accounts is £150 a year, so the compensation bill could be large.
However, the Financial Ombudsman said the issue with packaged accounts was not "the new PPI scandal".
It said many people had actually used the benefits.
It also said that it was only upholding around 10% of complaints, as in many cases it agreed with the compensation already offered by the banks.
But it advised customers to complain directly to their bank, rather than going through claims management companies, which currently handle 80% of the complaints received by the Ombudsman.
The full list of complaints made to the Financial Ombudsman is here.


Ivory Coast international Serge Aurier will be tried on 26 September for an alleged assault on a police officer.

The 23-year-old, who plays for Paris St-Germain, denies the charge and has himself filed a complaint against the police for violence, reports say.
He was originally arrested and placed in police custody early on Monday morning after an incident in Paris.
The incident occurred in the Champs Elysees area in the early hours of Monday as Aurier left a nightclub.
Paris St Germain officials said the club will wait for further information before making any comment.
Coach Laurent Blanc briefly suspended Aurier in mid-February after the defender posted a video online in which he insulted Blanc and fellow PSG players, including Zlatan Ibrahimovic and Angel di Maria.


Newport County's Football League status was secured as they ended Luton Town's three-match winning run and killed off their League Two play-off push.

Jack Marriott ensured the hosts' domination was rewarded as he headed in Olly Lee's cross after Joe Piggott had missed a host of Luton chances.
But Souleymane Coulibaly rescued County a point late on as the substitute striker nodded in Alex Rodman's cross.
Accrington's win over York mean the Minstermen drop out as County are safe.
Newport manager Warren Feeney told BBC Radio Wales: "When I first came in it was 'stay up at all costs' and (former manager) John Sheridan put the ground in there for me and I just tried to carry on what he left.
"And full credit to the players because people won't realise how hard it is down the bottom of that league.
"But they've responded and it's job done for us."


Rangers chairman Dave King faces a legal fight after defying an order to make an offer for all shares in the club's holding company.

The Takeover Appeal Board (Tab) ruled last month that King had "worked in concert" with three others to take control at Ibrox in 2015.
King did not meet Wednesday's deadline to make an offer of 20p per share.
Tab has now petitioned the Court of Session in Edinburgh in a bid to have its order enforced.
King could also face "financial cold shouldering", which means no city investors or institutions are allowed to deal with him.
At the time of last month's ruling, King said he did not agree with the findings or the share price, saying that, even if he proceeded with an offer, it would be rejected by an "overwhelming majority of RIFC's shareholders".
The Tab ruling said King, along with George Letham, George Taylor and Douglas Park, had acted as a "concert party" to acquire shares in Rangers International Football Club, rather than acting as an individual.
It said he was therefore required to make an offer to buy all the shares in the holding company.
There are approximately 87 million RIFC shares, with King, Letham, Taylor and Park owning 34%.


Scotland's First Minister Nicola Sturgeon said she was "increasingly concerned" about the possibility of an early EU referendum.

Some reports have suggested the prime minister, David Cameron, could call the vote in June.
Ms Sturgeon said a "longer period" might be needed for a campaign for continued UK membership.
The Conservative MSP, Alex Johnstone, said there would be "enough time" for people to make an informed decision.
Mr Cameron is seeking to renegotiate the terms of UK membership with other EU leaders before calling the "in/out" referendum.
At the weekend, he said he was "hopeful" of reaching a deal with other EU leaders in February and that the referendum "would follow".
He has previously committed to holding the ballot before the end of 2017.
Ms Sturgeon said she wanted the UK to remain in the EU, even though she believed a vote to leave could hasten another referendum on Scottish independence.
She urged Mr Cameron to get away from "a very narrow focus" on renegotiation issues and "get out there" to make the case for continued membership.
Otherwise she said he would lose ground to the leave campaign and be guilty of a "failure of leadership".
A Downing Street source said the debate over the UK's future relationship with the EU could not properly begin until renegotiation was completed.
Tory MSP Alex Johnstone said: "It's important that this [the EU referendum] is done quickly and that the referendum takes place as soon as we have a deal on the table.
"There will be time, there will be opportunity for people to look at that deal and consider it.
"But that can take a month or two months. It doesn't take two years.
"It's certainly enough time for people to judge the deal and for people to make an informed decision," he said.
A Scottish Labour spokesperson said: "It's essential that as many people as possible have their say."


Patients from Powys may have to wait longer for operations in English hospitals under plans to save money.

Many patients need treatment across the border because the county does not have a large hospital.
But they could have to wait at least 32 weeks under plans by Powys Teaching Health Board to save £2m this financial year.
According to Welsh government targets, only 5% of patients should spend more than 26 weeks on a waiting list.
The Welsh government said it expects everyone to be seen within its targets, which require 95% of patients to be treated within 26 weeks and for all patients to be treated within 36 weeks.
Powys Teaching Health Board said it will comply with the maximum 36 week "backstop" for non-urgent cases.
But it has written to a neighbouring NHS trust in England to say it will only pay for treatment carried out in a 32 to 36 week "window".
Powys's finance director told a board meeting in September that while there was a commitment to the 36-week limit, the board would be "utilising flexibility".
The Wales Audit Office has warned that the NHS in Wales is likely to be £70m in the red by April 2013.
In a worst case scenario, the watchdog says Powys could have a deficit of £9m at the end of the financial year.
The chief executive of the Welsh NHS told AMs this week that a £50m contingency fund was available to help balance the books.
At the end of September, 5,016 patients in Powys (98.4%) had spent fewer than 26 weeks on its waiting list, 82 (1.6%) had been waiting between 26 and 36 weeks and no-one had waited more than 36 weeks.
Of the more than 400,000 people across Wales on waiting lists, 91% had been waiting less than 26 weeks and 8% had been waiting between 26 and 36 weeks.
The move could save the board £2m in this financial year, according to minutes of the meeting.
In a letter to an NHS trust in Shropshire, seen by BBC Wales, Powys finance director Rebecca Richards says the board has decided to "extend the referral to treatment time (RTT) for its residents from 26 weeks to a maximum of 36 weeks, noting that no patients wait longer".
The letter to the Robert Jones and Agnes Hunt Orthopaedic Hospital NHS Foundation Trust in Oswestry adds: "What this means in practice is that we will allow a four-week window within which we expect patients to be treated and therefore RTT completions before 32 weeks and post 36 weeks will not be funded."
Shopshire trust chief executive Wendy Farrington-Chadd confirmed it had been informed to "increase the waiting times for Powys patients from 26 to 36 weeks for the remainder of the financial year".
She said the trust was working with Powys health boards and any urgent cases will continue to be prioritised.
In a statement, the health board said: "Powys Teaching Health Board is currently performing at above 98% against the 95% target for 26 weeks, however this level of performance is achieved at a significant cost.
"Within this context, a degree of slippage can be tolerated and the health board has taken steps to utilise the flexibility within the 95% target whilst still meeting it."
The Conservative AM for Montgomeryshire, Russell George, called on Health Minister Lesley Griffiths to intervene.
"I have had constituents coming to my office in tears, because effectively they have been told they are going have to wait a further 10 weeks, and remain in that discomfort and pain over that period," he said.
"The issue we have got is that we have a hospital in England treating English patients in 18 weeks, but cannot treat Welsh patients before 32 weeks.
"I think it is appalling."
A Welsh government spokesman said: "Officials have spoken with Powys Health Board and received assurances that there is no intention to move away from this policy and any providers within England that have received letters will be contacted to make this situation absolutely clear."


More than £55m has been raised so far for charity on Sport Relief's live TV show, ahead of a weekend of fundraising.

David Walliams, Alesha Dixon, Gary Lineker and Greg James were among those who hosted the BBC show, broadcast from London's Queen Elizabeth Olympic Park.
Highlights included a Some Mothers Do 'Ave 'Em sketch featuring tennis siblings Andy and Jamie Murray.
The total of £55,444,906 breaks the previous on-the-night record of £51m.
Britain's Got Talent judge Walliams, who has a long association with Sport Relief, revived Little Britain character Emily Howard for a sketch with former England footballer Peter Crouch.
Actor Idris Elba starred as Luther in a one-off sketch which reunited him with Ruth Wilson, who plays nemesis Alice Morgan in the BBC One crime drama.
The overall total included money raised by Sport Relief Challenges, including Jo Brand's Hell of a Walk.
The challenge saw the comedienne take on an incredible 135.7 miles as she walked across the UK from east to west, raising £1,159,220.
Eddie Izzard is still raising money for Sport Relief by running a gruelling 27 marathons in 27 days across South Africa. He has completed 24 marathons so far.
And BBC Radio 1 DJ Greg James raised more than £1m by completing a triathlon a day for five consecutive days, across five different UK cities.
Fundraising efforts will continue on Sunday as the Sainsbury's Sport Relief Games take place around the country.


Boris Johnson has said the Conservatives are "on the rise" in Wales ahead of May's assembly election.

The Mayor of London spent Tuesday campaigning in Wales, visiting Newport, Cardiff and Brecon, Powys.
He claimed Labour was "complacent" on health and education, and had no "divine right" to rule Wales, saying people "deserve better".
On the steel crisis, Mr Johnson said the UK government was "doing its absolute best" to sort it out.
"What you've seen in Wales over the last 17 years is a very, very complacent Labour administration," he said.
"They think that they can get away with anything. Services to the best of my knowledge have been deteriorating - you haven't got the proper health care that you need in this part of the country and I really want to see some progress.
"I really think that when you look at what has been happening in this part of our country in the last 17 years of Labour administration it isn't good enough - the people of Wales deserve better."
"They deserve not to have to wait so long for their appointments, they deserve access to the kind of cancer drugs that people in England can get automatically."
Mr Johnson would not be drawn on the subject of the EU referendum - both he and Welsh Conservative leader Andrew RT Davies support the campaign for the UK to leave the union.
Responding for Welsh Labour, a spokesman said: "That Andrew RT Davies's own party colleagues have to resort to vacuous bombastic attacks because of the dearth of policy ideas from the Welsh Conservatives speaks volumes.
"While the Welsh Tory leader joked around with Boris Johnson, Carwyn Jones was working to secure a future for Welsh steel."


BMW is to invest £250m in its UK factories over the next three years, the company has announced.

The money will be used to increase production of the Mini at its factories in Oxford, Birmingham and Swindon.
It comes on top of a £500m investment which was announced by BMW last June. More than 5000 British workers are involved in the production of the Mini.
BMW said the investment showed its commitment to Britain "as a vital manufacturing base".
"This investment is about securing jobs for the future," BMW's Graham Biggs told the BBC.
"We tend to build cars where we sell them, so the UK is a very important market for us - about the fourth largest in the world - so building Minis, Rolls-Royces and engines here makes a great deal of sense.
BMW said the investment would help its "international growth strategy" for the Mini as it introduced new models to the market.
In January it launched the Mini Roadster, a convertible version of the Mini Coupe, the first two-seater Mini model.
Both new cars are assembled at the main plant at Cowley, Oxford, which has produced more than two million Mini models since 2001.
As well as extra investment at the Oxford plant, the money will be earmarked for expanding production capabilities at the steel body pressings plant in Swindon and BMW's engine plant at Hams Hall, in the West Midlands.
However, BMW said that because of current capacity constraints at the Oxford plant, it was considering setting up "satellite production" of the Mini outside of the UK in the "medium term".
"We need to look for a flexible partner to help us build the cars and we're considering a contract with a Dutch contract manufacturer," Mr Biggs said.
The carmaker said it was in discussions with Nedcar, a subsidiary of Mitsubishi, to use its plant in Born, in the Netherlands. It will have spare capacity from 2013 following Mitsubishi's decision not to continue production of its Colt model there because of difficult economic conditions.
BMW has said that the Oxford plant will remain "the home and heart" of the Mini and will provide specialist advice on establishing the new facility.


Former UFC champion Ronda Rousey will make her comeback against Amanda Nunes on 30 December, more than a year after being knocked out by Holly Holm.

American Rousey, 29, lost her unbeaten record and the bantamweight title in the shock defeat last November.
She will try to reclaim her crown against champion Nunes of Brazil in the main event of UFC 207 in Las Vegas.
Rousey is the longest reigning UFC champion in women's mixed martial arts history.
She held the 135-pound crown for three years from November 2012 to November 2015.
In February, the Olympic judo bronze medallist said she "considered suicide" after her defeat by compatriot Holm.


The firm at the centre of a row about the poor care of an elderly woman in her home has been suspended by trade body, the UK Homecare Association.

The UKHCA says it is investigating Mosaic Community Care and that the suspension means it will not recommend Mosaic to elderly or disabled people.
Footage recorded by the family of Muriel Price, 83, showed carers not turning up for visits or arriving late.
Mosaic says it is working with the UKHCA to remedy the situation.
Regulator the Care Quality Commission has announced it will bring forward the date of Mosaic's next inspection in light of the footage, which was broadcast by the BBC on Thursday.
Mrs Price's grandson installed two CCTV cameras in her house in Blackpool, Lancashire, to monitor her so she could be helped if she fell while at home alone.
However, their recordings showed carers failing to turn up when they should and behaving inappropriately on occasions.
In footage seen by the BBC, which covered a period of nearly a month, carers turned up late or not at all on at least 12 occasions.
Several other visits were much shorter than the one hour the carers were contracted for.
While some carers were professional, the footage shows examples of others who were not.
The footage shows one carer sticking her fingers in food to check its temperature, while another changes incontinence pads in full view of the street.
And though Mrs Price is an insulin dependent diabetic with special dietary requirements, one carer admits to not being able to cook.
The UKHCA says it wants to ask Mosaic "what steps they've taken to address the care workers' behaviour recorded in the CCTV footage and that these have been effective".
When the BBC showed the CCTV footage to Care Minister Norman Lamb, he said it was "shocking and depressing".
In a statement, Mosaic Community Care said: "Following the BBC investigation surrounding former Mosaic Care user Muriel Price, UKHCA has temporarily suspended our membership.
"This suspension, which is standard practice, is pending satisfactory evidence that as an organisation, we took immediate action following the incidents highlighted - that we were aware of.
"We are working with UKHCA to remedy this situation and will be providing them with the relevant documentation and case history surrounding the case, along with evidence of the action we took to prevent this situation being repeated.
"As the professional association for homecare, UKHCA continue to support Mosaic Care with advice and training to address the issues raised by the footage."


A man who murdered his first wife in a car fire and tried to kill his second in another crash has been jailed for at least 30 years.

Former nurse Malcolm Webster, 52, was found guilty in May of murdering Claire Morris in Aberdeenshire in 1994.
Webster, of Guildford, Surrey, had also denied attempting to kill Felicity Drumm in New Zealand in 1999.
He was jailed for life for the crimes, committed as part of a plot to claim almost Â£1m in life assurance money.
At the High Court in Edinburgh, judge Lord Bannatyne said Webster - who must serve 30 years before he can apply for parole - had committed "cold-blooded, brutal and callous" crimes for financial gain.
He said: "The murder of your then wife was an appalling one and all right-minded people will be utterly shocked."
Ms Morris' family said Webster was a "monster".
Her brother, Peter Morris, said he believed that 30 years was "the correct sentence for an extremely dangerous criminal".
He told BBC Scotland: "It's more important that he's taken from society because of the damage he can cause to women.
"I would hate for that to happen to anyone else."
He also announced his intention to set up a foundation in his sister's name, aimed at improving the after-care for people involved in serious court cases.
Mr Morris said he wanted bereaved family members to be treated as important people rather than "second-class citizens".
Webster was found guilty after Scotland's longest-lasting single accused criminal trial, which began on 1 February at the High Court in Glasgow.
The jury, of nine women and six men, took less than four hours to find Webster guilty of all the charges, as part of frauds to obtain hundreds of thousands of pounds in life assurance.
The fatal crash in 1994 was originally treated as an accident.
Webster said he had swerved to avoid a motorcyclist.
However, the crash was later reinvestigated, after concerns were raised in the wake of the second crash, in Auckland.
New tests showed Ms Morris had traces of drugs in her system.
Ms Drumm, who also suspected that Webster had also been spiking her food and setting fire to their homes, alerted the authorities in New Zealand after surviving a car crash in which Webster was driving.
After the crash she realised he had cheated her of her life savings and was set to gain a huge payout in the event of her death. Webster then returned to the UK.
In a chance meeting, Ms Drumm's sister later told a UK police officer of her concerns, and this proved to be pivotal in the case.
Webster was also found guilty of intending to bigamously marry Simone Banarjee, from Oban, Argyll, to gain access to her estate.
He pretended to have leukaemia, and during the deception he shaved his head and eyebrows.
In January 2008 police warned her about Webster's past as they closed in on him.
She told BBC Scotland that at first she found what they were saying hard to believe.
"I thought it was complete nonsense. This could not be the Malcolm Webster that I had known and loved," she said.
But looking back Ms Banarjee said she now realises the danger she was in.
"I do believe I am very lucky," she said. "I think if it wasn't for Strathclyde Police things may have turned out very, very differently."
Ms Banarjee described Webster as a "clever man" and said people's first impression of him was of a "fine, well spoken, nicely dressed person with nice manners".
But she said she thought his intelligience made him very dangerous.
She added: "He learns from everyone he meets. If I had my way I would make sure that he is in solitary confinement for the rest of his days because he will learn and if he is ever released he will be an increasing danger to anybody else he meets."
Advocate depute Derek Ogg QC said in his closing speech that Webster was "a most cruel, practised deceiver" who, if convicted, would become one of the most notorious murderers of modern times.
However, defence counsel Edgar Prais QC said that although Webster was a "liar", a "thief", a "philanderer" and a "rat bag", he was not a killer.
The family of Webster's first wife have since asked him to hand over her grave.
Claire Morris' brother Peter wants to replace her headstone in Aberdeenshire, which still bears her married name and refers to a "dear wife".
Mr Morris asked Webster, through his solicitor, to hand over the lair - but the request was rejected.
Aberdeenshire Council had earlier confirmed that changes to the gravestone, at Tarves, needed the authority of the owner.
Meanwhile, police are also investigating concerns over the deaths of three children at a hospital in Abu Dhabi where Webster worked in the 1980s.


Robert Lewandowski scored twice as Bayern Munich beat Schalke 3-0 to move within two more wins of a fourth successive Bundesliga title.

Lewandowski ended a four-game goalless run with two in 11 second-half minutes to make it 38 for the season, firing in on the turn and then heading home.
Arturo Vidal then side-footed Bayern's third as Pep Guardiola's side secured a fifth successive league win.
Second-placed Borussia Dortmund play at home to Hamburg on Sunday (14:30 BST).
Bayern were rarely threatened by a Schalke side whose hopes of Europa League qualification are continuing to fade, with just one win from their last five games.
Bayern, who overcame Benfica to reach the semi-finals of the Champions League on Wednesday night, are chasing a treble, with a German Cup semi-final to come at home to Werder Bremen next Tuesday night.
Bayern Munich coach Pep Guardiola: "I was a footballer myself and I know how hard it is to play three days after a Champions League game.
"But that is no excuse. In the first half we didn't play for long periods and the difference between the first and second half was huge.
"I'm happy with the win and in the league we have taken a big step forward.
"Now we want to reach the cup final and I hope this game was a lesson for our players for Tuesday against Bremen."
Bayer Leverkusen moved into third place in the table with a 3-0 win over struggling Eintracht Frankfurt.
They went above Hertha Berlin, who lost 2-1 at Hoffenheim as the home side boosted their survival hopes with a fourth win in five games.
Augsburg helped their fight against relegation with a 1-0 win over Stuttgart to give them a second successive victory.
And Werder Bremen, who are third from bottom, also kept in touch with the teams above them thanks to a first win in five matches against Wolfsburg.


The owner of a 17,000-tonne oil rig which ran aground on the Western Isles last year has paid the Maritime and Coastguard Agency (MCA) £400,000.

The decommissioned Transocean Winner came ashore at Dalmore, near Carloway on Lewis, in a storm while being towed to the Mediterranean.
Its owner Transocean has paid the money requested by the MCA to cover costs in dealing with the incident.
The rig was eventually taken back under tow and scrapped in Turkey.
The rig's grounding last August sparked pollution fears due to the 280 tonnes of diesel on board.
Investigations found two of its four fuel tanks were damaged in the incident which resulted in the loss of 53,000 litres of fuel, most of which is thought to have evaporated with no damage to the environment.
Three weeks later it was towed to the safer anchorage at Broad Bay before being floated on to the deck of the Hawk, a semi-submersible ship used for transporting large maritime structures over long distances.


The founder of the Sharia Watch pressure group is launching a bid to be the next UKIP leader on Saturday.

Anne Marie Waters was blocked from standing for UKIP at the election, with then leader Paul Nuttall saying her views made him "uncomfortable".
She campaigns against Sharia law in the UK and has called Islam "evil".
UKIP said the campaign launch was "not in any way an official UKIP event" and urged members to "think very carefully" before attending.
A UKIP spokesman said all leadership candidates would be vetted by the party's National Executive Committee, who will decide which ones will be allowed to go forward to a vote of the membership.
Waters had planned to launch her leadership bid at Rotherham football club but has been forced to find an alternative venue.
"There were concerns about my 'views' and no doubt, police were happy to add to such concerns", she said in a statement on her website.
South Yorkshire Police has said the decision to cancel the event at Rotherham's New York stadium was taken by the club.
The launch will now take place at an undisclosed location in Rotherham. Waters took part in a "silent protest" march against grooming gangs in the town last year.
In a joint statement, UKIP MEP Jane Collins and councillor Allen Cowles, leader of UKIP's Rotherham branch, said they supported the decision to cancel the planned stadium rally and urged the party's councillors to boycott Waters' campaign launch.
Mr Cowles said: "UKIP councillors wish to make it clear that they do not condone in any way the views Ms Waters has previously expressed, or what she stands for."
Waters announced her plans to stand for the UKIP leadership at a rally in Manchester earlier this month, where she was introduced by former English Defence League leader Tommy Robinson.
She told the cheering crowd "Islam is a killing machine" and urged them to "join UKIP and vote for me," adding that the party will "try to stop me".
After the Brexit vote, UKIP's leadership was aware the party had to broaden its appeal.
The former leader, Paul Nuttall, backed a radical policy platform with social integration at its core.
He said the party would shape the debate around extremism and Islamism in the way it claimed to have done with immigration - daring to address topics other politicians wouldn't.
But while some in UKIP welcomed the policies announced in the election manifesto - including a ban on face coverings - they caused disquiet among other members who feared the party was in danger of being seen as Islamophobic.
Mr Nuttall insisted that was not the case, saying the focus was breaking down barriers in society and improving integration.
But UKIP is sensitive to public perception about its policy and direction. Having been dogged by allegations of racism in the past, it's determined not to go there again.
A former Labour Party activist, Waters set up a UK branch of anti-mass immigration organisation Pegida with Robinson, but is no longer thought to be involved with the group.
She founded Sharia Watch UK, which aims to "to document the advancement of Sharia law in Britain," in 2014.
She hit the headlines a year later when she announced plans for an exhibition of cartoons of the Prophet Muhammad, but was forced to cancel the event after police warned it could be "a risk to public safety".
She has argued that UKIP could regain support if it had the "guts" to be "honest about Islam" and challenge the view that it has "nothing to do" with jihadist violence.
Anti-fascist campaign group HopeNotHate has branded Waters a "toxic figure" and urged UKIP to expel her from the party.
But she has been defended by former UKIP leadership contender Raheem Kassam, editor of the Breitbart London website, who wrote earlier this year: "If UKIP ditches Anne Marie Waters, the party is over".
The UKIP leadership contest was triggered by the resignation of Paul Nuttall, when the party failed to win any seats at the general election and saw its share of the vote collapse.
Mr Nuttall, who campaigned for a ban on burkas and Sharia courts, said in April that Waters' comments were "way above and beyond party policy" and some had made him feel "a bit uncomfortable".
London Assembly member Peter Whittle and Ben Walker, a former UKIP councillor in South Gloucestershire, have also announced leadership bids.
MEP Bill Etheridge, who came third in the first of UKIP's two leadership contests last year, and Thanet council leader Chris Wells have both said they might stand if Nigel Farage cannot be persuade to return to the job he quit after last year's Brexit referendum.
The former UKIP leader has not ruled out a bid.


An Israeli court has extended former Prime Minister Ehud Olmert's 18-month jail sentence for bribery by a month.

The court rejected a plea bargain that would have seen Olmert serve six months for obstruction of justice concurrently with the bribery sentence.
Instead, he will serve five months concurrently and one consecutively.
Olmert, prime minister from 2006 to 2009, will become the first former head of government in Israel to go to prison when his sentence begins on Monday.
The 70 year old was handed a six-year sentence in 2014 after being found guilty of accepting, while he was mayor of Jerusalem, a 500,000-shekel ($129,000; Â£89,000) bribe from developers of one real estate project and a 60,000-shekel bribe in connection with another project.
But the Supreme Court subsequently cleared him of the charge of accepting the 500,000-shekel bribe and reduced his sentence to 18 months.
The Supreme Court is yet to rule on an appeal by Olmert against an eight-month prison sentence he was handed last year after being convicted of fraud and breach of trust for accepting illegal payments from an American businessman.
Olmert has denied accepting bribes or illegal payments, but did admit to attempting to persuade his former secretary not to testify against him.


A motorcyclist has died and his passenger is seriously injured in hospital after a crash with a car.

The 49-year-old man from Rochester died at the scene on the A252 in Chilham, Kent, at 13:48 BST on Sunday.
His passenger, a 43-year-old woman from Gillingham, was taken to hospital with life-threatening injuries.
The driver of the Vauxhall Zafira involved suffered minor injuries. Police are appealing for any witnesses to the collision to come forward.


A haul of planets from Nasa's Kepler telescope includes a world sharing many characteristics with Earth.

Kepler-452b orbits at a very similar distance from its star, though its radius is 60% larger.
Mission scientists said they believed it was the most Earth-like planet yet.
Such worlds are of interest to astronomers because they might be small and cool enough to host liquid water on their surface - and might therefore be hospitable to life.
Nasa's science chief John Grunsfeld called the new world "Earth 2.0" and the "closest so far" to our home.
It is around 1,400 light years away from Earth.
Jon Jenkins, Kepler data analysis lead at Nasa's Ames Research Center in California, added: "It's a real privilege to deliver this news to you today. There's a new kid on the block that's just moved in next door."
The new world joins other exoplanets such as Kepler-186f that are similar in many ways to Earth.
Determining which is most Earth-like depends on the properties one considers. Kepler-186f, announced in 2014, is smaller than the new planet, but orbits a red dwarf star that is significantly cooler than our own.
Kepler-452b, however, orbits a parent star which belongs to the same class as the Sun: it is just 4% more massive and 10% brighter. Kepler-452b takes 385 days to complete a full circuit of this star, so its orbital period is 5% longer than Earth's.
The mass of Kepler-452b cannot be measured yet, so astronomers have to rely on models to estimate a range of possible masses, with the most likely being five times that of Earth. If it is rocky, the world would likely still have active volcanism and its gravity could be roughly twice that on our own planet.
The new world is included in a haul of 500 new possible planets sighted by the Kepler space telescope around distant stars.
Twelve of the new candidates are less than twice Earth's diameter, orbiting in the so-called habitable zone around their star.
This zone refers to a range of distances at which the energy radiated by the star would permit water to exist as a liquid on the planet's surface if certain other conditions are also met.
Of these 500 candidates, Kepler-452b is the first to be confirmed as a planet.
Dr Suzanne Aigrain, from the University of Oxford, who was not involved with the study, told BBC News: "I do believe the properties described for Kepler-452b are the most Earth-like I've come across for a confirmed planet to date.
"What seems even more significant to me is the number of planets in the habitable zone of their host stars with radii below two Earth radii; 12 is quite a few compared to the pre-existing Kepler planet catalogue.
"It bodes well for their attempts to provide a more robust measure of the incidence of Earth-like planets, which is the top-level goal of the Kepler mission."
While similar in size and brightness to the Sun, Kepler-452b's host star is 1.5 billion years older than ours. Scientists working on the mission therefore believe it could point to a possible future for the Earth.
"If Kepler-452b is indeed a rocky planet, its location vis-a-vis its star could mean that it is just entering a runaway greenhouse phase of its climate history," explained Dr Doug Caldwell, a Seti Institute scientist working on the Kepler mission.
"The increasing energy from its aging sun might be heating the surface and evaporating any oceans. The water vapour would be lost from the planet forever."
"Kepler-452b could be experiencing now what the Earth will undergo more than a billion years from now, as the Sun ages and grows brighter."
Dr Don Pollacco, from Warwick University, UK, who was not involved with the latest analysis, told the BBC: "Kepler data allows you to estimate the relative size of a planet to its host star, so if you know the size of the host, hey presto, you know the size of the planet.
"However, to go further - i.e. is it rocky? - involves measuring the mass of the planets and this is much more difficult to do as the stars are too far away for these measurements (which are incredibly difficult) to make.
"So in reality they have no idea what this planet is made of: It could be rock but it could be a small gassy ball or something more exotic maybe."
Dr Chris Watson, from Queen's University Belfast, UK, commented: "Other Kepler habitable zone planets may well be more Earth-like in this respect. For example, Kepler-186f is approximately 1.17 Earth radii, and Kepler-438b is approximately 1.12 Earth radii.
"In fact, at 1.6 Earth radii, this would place Kepler-452b in a category of planet called a 'Super-Earth' - our Solar System does not actually have any planet of this type within it! Super-Earths are hugely interesting for this reason, but one might then say, well, is it really 'Earth-like' given all this?"
He added: "When we look at the type of star Kepler-452b orbits, then it seems to be a star not too dissimilar to our Sun... The other Kepler habitable zone planets that have been discovered so far tend to be orbiting M-dwarfs - stars far cooler than our Sun, and therefore the planets need to orbit much closer to receive the same levels of heating.
"So it may be a potentially rocky super-Earth in an Earth-like orbit (in terms of host star and orbital distance). It's this combination of the host star and orbit that set it apart in my opinion."
The findings have been accepted for publication in The Astronomical Journal.

The trial of a group of people accused of breaking into and occupying the home of an evicted man has collapsed.

Following a long-running dispute over mortgage payments, 64-year-old Tom Crawford was evicted from his house in Nottingham in July.
Seven people including Mr Crawford's son were accused of breaking into the property in the weeks that followed.
But their trial, which began last week, was halted because of inconsistencies in evidence from key witnesses.
Updates on this story and more from Nottinghamshire
Mr Crawford's son Craig reacted to the acquittal on his Facebook page.
He posted: "Well well well!!!! Not guilty. Four of us representing ourselves.... Awarded costs! Winners!!!! #neverbackdown".
His father, from Carlton, had disputed claims he owed Bradford & Bingley £43,000 in mortgage payments.
He said he had paid off the endowment mortgage he took out in 1988, and that the terms were changed without his knowledge.
In January 2015, more than 250 people blocked an attempt to evict him and his wife Sue from their home in Fearn Chase.
But he ultimately lost the case, and was evicted in July.
Following the eviction, fencing was erected around the house, with guards and dogs patrolling 24 hours a day.
During the trial, Leicester Crown Court heard that a group of protestors smashed their way into the bungalow and sealed themselves in the roof space.
The court was also told that one security guard, who was protecting the house, had red paint sprayed in his face.
The seven people were on trial for conspiracy to commit criminal damage as well as conspiring to commit aggravated trespass.
However, the Crown Prosecution Service (CPS) said: "During the course of the trial, the evidence given by key witnesses differed substantially from the version of events described in their statements.
"Following a review, the CPS decided that there was no longer a realistic prospect of a conviction, so ended proceedings by offering no evidence."
Craig Crawford, 31, of Nottingham, Martin Atkin, 42, of Long Eaton, Mark Hawkins, 52, of Nottingham, Mark Haining, 51, of Nottingham, Henry Kellie, 48, of Market Harborough, Elizabeth Shier, 41, of Nottingham, and James Bradley, 42, of Wigan, had all denied the charges.


David Cameron has promised to create a "partnership for growth and reform" as he visits China on a trade mission with more than 100 UK business leaders.

The PM, who met Chinese Premier Li Keqiang on Monday, also pledged to put his "full political weight" behind a proposed EU-China trade agreement.
On Tuesday, Mr Cameron urged business people at a lunch in Shanghai's business centre to invest in the UK.
He said the UK and China had "deep complementary economies".
"If you are investing in Britain, invest more," he said.
"If you are thinking of investing in Britain, come and find us. You will get a warm welcome."
He won applause as he outlined plans for same-day visas for business visits to the UK and later tried his hand at speaking Mandarin,
On Monday, Premier Li Keqiang said the pair had agreed in their talks to "push for breakthroughs" on nuclear power and high-speed rail.
The leaders read out statements to reporters after their talks in Beijing's Great Hall of the People, but did not take questions.
Mr Li said the talks had been "highly productive", adding that the UK and China had become "indispensible partners for each other's development".
"On infrastructure, the two sides have agreed to push for breakthroughs and progress in co-operation on our enterprises in nuclear power and high-speed railway," he continued.
"The Chinese side is willing to not only participate but also purchase equities and stocks in UK nuclear power projects, and the UK side is open to this idea."
Mr Li and Mr Cameron announced that they had also agreed a £200m research fund aiming to foster scientific collaborations.
The UK PM said: "I see China's rise as an opportunity not just for the people of this country but for Britain and the world.
"Britain wants China to realise its dream and I believe we can help each other succeed in the global race."
Mr Cameron criticised opponents of trade liberalisation with China.
"Some in Europe and elsewhere see the world changing and want to shut China off behind a bamboo curtain of trade barriers. Britain wants to tear these trade barriers down," he said.
"An open Britain is the ideal partner for an opening China... No country in the world is more open to Chinese investment than the UK."
Mr Cameron promised to "champion an EU-China trade deal with as much determination as I am championing the EU-US trade deal".
He believes the EU deal could be worth "tens of billions" of pounds a year - including £1.8bn for the UK alone.
Writing in Chinese magazine Caixin, Mr Cameron declared his ambition to use this week's visit to help forge "a partnership for growth and reform that can help to deliver the Chinese dream and long-term prosperity for Britain too".
He welcomed signals from last month's third plenum of the ruling Communist Party that China wanted to open up more under the leadership of President Xi Jinping, who took up office a year ago.
By Nick RobinsonPolitical editor
Mr Cameron added: "Britain is uniquely placed to make the case for deepening the European Union's trade and investment relationship with China.
"Building on the recent launch of EU-China negotiations on investment, and on China's continued commitment to economic reform, I now want to set a new long-term goal of an ambitious and comprehensive EU-China free trade agreement.
"And as I have on the EU-US deal, so I will put my full political weight behind such a deal which could be worth tens of billions of dollars every year."
Mr Cameron believes that eliminating tariffs in the 20 sectors where they are highest, such as vehicles, pharmaceuticals and electrical goods, could save UK exporters £600m a year.
During the first day of his second trip to China as prime minister, he also attended the official opening of a new academy in Beijing for training technicians, salesmen and service staff for Jaguar Land Rover, which is signing a £4.5bn agreement to provide 100,000 cars to the National Sales Company over the next year.
JLR chief executive Ralf Speth is among the 120-strong business delegation accompanying Mr Cameron, along with executives from major exporters like Rolls-Royce, BP, Royal Dutch Shell, Barclays, HSBC, GlaxoSmithKline, Arup and Virgin.
But figures from smaller businesses, such as Westaway Sausages of Devon, Moulton bicycles and the Cambridge Satchel Company make up the bulk of the party.
Mr Cameron said: "I hope that by advancing and extending our bilateral trade, by working together on the global issues that affect us all and by maintaining an honest and open dialogue, my visit to China can plant the seeds of a long-term relationship which will benefit China, Britain and the world for generations to come."
The visit represents a warming of relations after a dispute over the prime minister's decision to meet the Dalai Lama in May.
And it comes six weeks after Chancellor George Osborne led a business delegation to China.
The UK opposition leader Ed Miliband warned that the government thought "that for the majority, insecurity, low pay and squeezed wages are simply an immutable fact of life, the only way we can compete".
He said: "The only way we can compete with China - and the only way Britain can win - is by winning a race to the top.... where we compete on the basis of high-skill, high-tech, high-wage economy."
The UK Independence Party's leader Nigel Farage said that the UK was being constrained by its membership of the European Union.
"We should be carving out trade deals to suit our businesses, our expertise, our interests and needs, not having to comply with a compromise designed to accommodate the whole EU including those inside the failing Eurozone," he said.
Mr Osborne's Autumn Statement, which sets out the UK government's tax and spending proposals, has been put back 24 hours to accommodate Mr Cameron's trip, and will take place this Thursday, instead of Wednesday.


Northampton Saints earned a third Premiership victory in a row but they had to battle to overcome a resurgent Bristol at Franklin's Gardens.

Bristol played their part in a superb game and deserved the losing bonus point which saw them move to within one point of 11th-placed Worcester.
Bristol's Jason Woodward scored a try, two conversions and four penalties.
But Louis Picamoles, Mike Haywood, Tom Wood and JJ Hanrahan's tries gave the hosts a valuable bonus-point victory.
Nick Fenton-Wells had also crossed for the visitors in an even first half, and a draw had looked likely at 26-26 in the closing stages.
But a Stephen Myler penalty and then a late Harry Mallinder drop goal clinched it for Saints.
Bristol, who were without suspended centre Tusi Pisi, were bidding for a shock third straight league win after losing their first 10 Premiership games since promotion.
They were inspired by an in-form Woodward, who combined well with Tom Varndell for arguably the best try of the match, crossing under the posts after a swift counter.
Picamoles and Myler were at the centre of most things Saints did well, as they moved up to fifth in the table after exerting a strong spell of pressure in the final 15 minutes.
Northampton first-team coach Alan Dickens:
"There was an air of frustration afterwards, but we will take the win.
"When we scored our third try there was a time where we thought we were going to go away from them and then we lost the ball about 30 metres from their line, it might have been Alex Waller, and from the resulting scrum they had the chip-kick and scored under our posts.
"Credit to Bristol, they are a much-improved team from the one we beat in the second game of the season. Fair play to the job Mark Tainton has done over recent weeks.
"They have picked a more mobile team and Woodward is an addition for them, plus they are getting the best out of Tom Varndell, they looked to feed those two today and it nearly paid off."
Bristol head coach Mark Tainton:
"It is a massive point. It is down to us, we can't rely on other people and we will just try to improve each week and concentrate on what we are doing.
"The team have got belief now and with that comes confidence. When you have got confidence you can achieve anything and we nearly achieved something special this evening. We have got the point, we are disappointed we didn't get more, but we will take that with where we are.
"We played some really good attacking football and our defence was solid. We were probably second best in the breakdown at a number of occasions, and it allowed Northampton to pinch ball and get them field position again. If you allow Northampton field position they will eventually score points, but I am proud of the performance.
"The boys played exactly how we asked them to play it, and that was to attack that wide channel and get on the outside of them. Late in the game we scored a superb try by Jason Woodward by going wide in our 22, and then we maybe got a little bit loose rather than playing field position, but I am never going to say to the guys 'stop playing rugby'."
Northampton: Foden; Elliott, Burrell, Hanrahan, North; Myler, Groom; Waller, Haywood, Brookes, Lawes, Day, Wood (capt), Harrison, Picamoles.
Replacements: Clare, Waller, Hill, Craig, Gibson, Dickson, Mallinder, Estelles.
Bristol: Woodward; Wallace, Palamo, Hurrell, Varndell; Jarvis, Cliff; Traynor, Hawkins, Ford-Robinson, Tuohy, Glynn, Fenton-Wells, Robinson (capt), Eadie.
Replacements: Crumpton, Bevington, Cortes, Sorenson, Lam, Williams, Searle, Arscott.

A third man has been charged with the murder of a teenager who was stabbed during a fight in Birmingham.

Sheriff Mbye, 18, of Lee Bank, died in hospital on 17 April after being stabbed several times on Bristol Road South, Northfield, police said.
Montell Stephens, 18, of Smethwick, who was injured and taken to hospital, was charged, the West Midlands force said.
Mr Stephens, of William Savage Way, is due at Birmingham Magistrates' Court on Friday.
Rakeem Riley, 18, of no fixed address, and Omar Robinson, 21, of Rann Close, Ladywood, have previously been charged with murder.


About 400,000 Volkswagen cars in the UK will need fuel injectors altered as well as a software fix, its UK boss said.

Paul Willis, UK managing director, said that cars fitted with the 1.6L diesel engine would need the physical remedy.
Those with the larger 2L engine would only need a software fix, he told the Commons Transport select committee.
Mr Willis apologised "sincerely and unreservedly" for letting down customers.
"Volkswagen has significantly let down its customers and the wider public... we recognise we've fallen short of the standards expected and we will take all the necessary steps to regain trust."
He told the MPs it was in 2008 that VW first sold cars in the UK with engines that could cheat emissions testing.
A total of 1.2 million UK vehicles had been affected, but the remaining two thirds would only need software altered, Mr Willis explained.
The total included 583,000 Volkswagens, 393,000 Audis, 132,000 Skodas and 77,000 Seats. Only Germany had more vehicles affected by the problem than the UK.
Mr Willis said that recalls of UK vehicles would start in the first quarter of 2016.
Owners who might be inconvenienced by not having a vehicle during the recall process would be given a loan car, the VW boss added.
Asked more technical questions about the emissions scandal, Mr Willis explained that his role involved responsibility for sales, marketing and finance, and that engineering was handled by the firm's team in Wolfsburg. "I'm not an engineer," he said several times.
Transport secretary Patrick McLoughlin told the MPs on the committee that the scandal would cause VW "very substantial damage".
He said a move to on-the-road testing of vehicle emissions - as opposed to laboratory testing - would render any defeat devices useless: "We have been right to press for real-world testing ... and we will see changes across Europe on that front."
Asked whether any other car makers had used similar software to evade emissions regulations, Mr McLoughlin said he was satisfied they had not on the basis of their responses. However, some had yet to answer his queries, he added.
Mike Hawes, chief executive of industry body the SMMT, said it was too soon to say whether the reputation of the wider automotive sector would be affected by revelation of VW's emissions cheating.


A teenager who hurled abuse at child murderers Rachel and Nyomi Fee outside court has been spared jail.

Her lawyer successfully argued that she might be regarded as "some kind of hero" if she was sent to prison.
At Livingston Sheriff Court the 17-year-old, who cannot be named for legal reasons, admitted shouting homophobic abuse at the couple.
A television news crew recorded her comments as they filmed the pair arriving at court for their trial.
They were found guilty on Tuesday of murdering Rachel's son, Liam Fee, and of abusing two other children.
The teenager, from Livingston, pled guilty to behaving in a manner likely to cause a reasonable person fear or alarm by shouting and swearing aggravated by sexual orientation.
Sheriff Jamie Gilmour took other unrelated offences into account when he sentenced her to be electronically tagged on a nine-month curfew.
He also placed her under supervision for two years and ordered her to carry out 200 hours of unpaid work within nine months.


A blue plaque honouring a prominent miners' leader and trade unionist is to be unveiled in Rhondda Cynon Taff.

Arthur James Cook was general secretary of the Miners' Federation of Great Britain from 1924 until 1931, which included leading the miners during the 1926 General Strike.
The unveiling of the blue plaque is taking place at Rhondda Heritage Park on Saturday.
The council said it would be "displayed in a prominent place for all to see".
Born in Somerset in 1883, soldier's son Mr Cook spent his childhood growing up in the west country before moving to Porth in the Rhondda Valley aged 18 and later to Merthyr Tydfil to work in the coal mines.
He became involved in politics while working at the Lewis Merthyr Colliery in Trehafod, coming to prominence during the 1910 miners strike.
As well as becoming general secretary, Mr Cook's other roles included becoming secretary of the International Miners' Federation.
He died in 1931, aged 47, after a battle with cancer.
Councillor Joy Rosser, cabinet member for prosperity, wellbeing and communities, said: "Rhondda Cynon Taff has been the home of so many influential people in history and it is fitting that a blue plaque in honour of A J Cook is unveiled at Rhondda Heritage Park, the place where he once worked."
The plaque has been funded by the Association of Friends of Rhondda Heritage Park.


George Thomas scored the only goal of the game as Coventry City climbed off the foot of the table with victory over 10-man Walsall.

The young striker, who also got the winning goal when Coventry won the EFL Trophy at Wembley earlier this month, netted seven minutes before the interval to bring a welcome win for Mark Robins' side.
Coventry, who have been in the relegation zone since November and bottom for three months, had already been condemned to relegation. But, with just a game left, they at least climb above Chesterfield, who lost at home to Charlton.
The Saddlers should have taken the lead in the 32nd minute when Matt Preston headed wide from inside the area. And he was quickly made to pay when, on 38 minutes, Thomas stroked the ball home from the edge of a crowded penalty area.
Gael Bigirimana headed off the line from Eoghan O'Connell 11 minutes into the second half, while the home side survived strong claims for a penalty when the ball hit the hand of Jordan Willis.
In only his third game back after a month out through injury, Walsall then had O'Connell sent off for a second yellow card with 20 minutes remaining, ruling him out of the mid-table Saddlers' home game with relegation battlers Port Vale on Tuesday night.

An app to support those at risk of suicide in the north east of Scotland has been accessed by more than 6,000 people in the six months since it launched, BBC Scotland has learned.

National body Choose Life is behind "Prevent Suicide - Northeast Scotland" and an accompanying website.
The technology is aimed at being a stepping stone to specialised support.
More than 60 people took their own life in Aberdeen and Aberdeenshire last year.
Local Choose Life coordinator Iain Murray said: "Not everyone accesses the services that they perhaps need.
"The app, for me, bridges that gap.
"You can take a bit of personal responsibility and that's where you can start to build your own plan.
"It gives you that first step."
In January, it was warned that the growing numbers of job cuts in the oil industry was having a dangerous impact on the mental health of some workers.


A court in Russia has placed the prominent opposition activist Sergei Udaltsov under house arrest.

Mr Udaltsov is charged with organising "mass disorder" during a protest in Moscow in May 2012. He was arrested in October before being released.
The leader of the Left Front coalition has rejected the accusation, saying it is an attempt to discredit the opposition to President Vladimir Putin.
If convicted, Mr Udaltsov faces between four and 10 years in prison.
It is the first time that a Russian opposition activist has been placed under house arrest, the BBC's Oleg Boldyrev reports from Moscow.
Two other activists - Konstantin Lebedev, an aide to Mr Udaltsov, and Leonid Razvozzhayev, an aide to opposition MP Ilya Ponomarev - were charged alongside Mr Udaltsov in October but were remanded in custody.
Mr Razvozzhayev said he was abducted in Ukraine, smuggled into Russia and forced into signing a confession, which he later disavowed.
On Saturday, investigators asked that Mr Udaltsov be placed under house arrest by the court in Moscow's Basmanny district because he had not been exhibiting good behaviour and had not co-operated with them.
The court ruled that he stay inside his flat, limited his communications to his closest relatives and his lawyers, and banned him from using the internet, our correspondent reports.
The house arrest will last until early April when the investigation is expected to conclude.
Speaking to journalists before the verdict, Mr Udaltsov said he considered the new restrictions a purely political move, our correspondent says.
Some supporters in the courtroom shouted "shame on the judge" during the hearing, he adds.
The case against the three activists centres on a documentary broadcast by the pro-Kremlin television channel NTV which allegedly shows them discussing efforts to topple the Russian government with an official from neighbouring Georgia and seeking financial support.
Mr Udaltsov said the footage was a sham and the documentary "dirt and lies". He and the other two men pleaded not guilty in October.
In November, Investigative Committee spokesman Vladimir Markin said it had gathered new evidence supporting the allegation aired in the documentary that the activists had met foreign officials to plot mass riots.
He said their supporters had received special training abroad.
Analysts say Mr Udaltsov's arrest was part of a crackdown on the organisers of anti-government protests which began in December 2011 amid allegations that the parliamentary elections that month were rigged.


Singapore says it has arrested eight Bangladeshi men accused of plotting terror attacks in Bangladesh.

Singapore's Ministry of Home Affairs said they were members of a group set up in March called Islamic State in Bangladesh (ISB).
The men, aged 26 to 34, had been working in the construction and marine industries.
Singapore is increasingly concerned about the spread of militant jihadism in neighbouring countries.
In January, it arrested 27 Bangladeshi workers - deporting 26 - accused of supporting militant Islam.
The ministry said the eight men held in April had intended to join the so-called Islamic State militant group.
But after deciding it would be too hard to travel to Syria they instead planned to return to Bangladesh to overthrow the government and had "identified several possible attack targets".
Money, bomb-making instructions and extremist recruitment material was seized from the men, officials added.
There was no indication of plans to target Singapore, said the statement.


Antrim suffered a last-gasp 2-18 to 1-20 defeat by Meath in the Christy Ring Cup final but the game ended amid confusion with suggestions that the score had been miscalculated.

Journalists in Croke Park felt the score in Croke Park was 2-17 to 1-20 which would have meant extra-time.
But Meath were presented with the cup as the Antrim county team's malaise of recent times continued.
Sean Quigley hit a late 1-1 to spark Meath celebrations.
However, the doubts over the scoreline suggest that this fixture may not be quite over yet.
Antrim appeared totally in control early on as Conor Johnston's 15th-minute goal and scores from Niall McKenna, James Connolly and Ciaran Clarke helped them lead 1-7 to 0-1 after 19 minutes.
However, four James Toher points saw Meath cutting Antrim's lead to 1-10 to 0-7 by the interval.
Meath were right in the contest five minutes after the restart as Neil Heffernan smashed in a superb goal.
However, Antrim seemed to have regained the initiative as four successive points - including two Eddie McCloskey efforts - left them five ahead.
However, points from Joe Keenan and Adam Gannon kept Meath very much in touch before substitute Quigley's late scores saw the Royals snatching the county's first Christy Ring Cup title.
Armagh suffered a second straight Nicky Rackard Cup final defeat as Mayo earned a 2-16 to 1-15 victory.
Kenny Feeney starred with a 1-9 haul for the Connacht men as they headed west with the silverware
Darren McTigue's third-minute goal gave Mayo a great start before David Carvill, Ryan Gaffney and skipper Cathal Carvill responded with Armagh scores.
Mayo regrouped to lead by four but Armagh fought back to trail by the minimum, 0-9 to 1-5, at the interval.
Armagh took the lead straight after the restart as Eoin McGuinness finishing clinically to the net after Coulter had made a searing run through the heart of the Mayo defence.
Mayo responded with three points in the spin from Shane Boland, Feeney and substitute Fergal Boland had them back level.
Armagh eased back in front through Coulter and Gaffney, but Mayo found another gear, with Cathal Freeman and Keith Higgins providing the impetus from deep.
In the 57th minute Feeney banged in a goal, but Armagh responded with three more points, the best of them from Coulter, brought the sides level.
However, that was as good as it got for Armagh as Feeney, Sean Regan and substitute Corey Scahill hit spectacular points to clinch Mayo's win.


Northern Ireland manager Michael O'Neill has hailed the impact made by goalscorers Conor Washington and Jamie Ward in Sunday's 2-0 World Cup Group C qualifier win over Norway in Belfast.

Both strikers scored in the first half to secure a vital win at Windsor Park.
"They both give you that energy at the top end of the pitch. Conor likes to fight for the ball and Jamie is the same," said O'Neill.
"Jamie set the tone from the off and the rest of the team followed suit."

"He won his first header, then there was some great link-up play and it's a superb finish for the goal."
The victory sees Northern Ireland lie second in the group on 10 points, two points ahead of the Czech Republic, with a game away to Azerbaijan on 10 June next on the agenda.
"This was a great result for us and we can now look forward to a difficult game in Azerbaijan but we know a win there would put us six points clear of them and we are now seven ahead of Norway. We are looking at the Czech Republic and they will be looking at us.
"There is still a lot of football to be played but when you get to this point, we just want to maintain the form we are in and ensure that when the Czech Republic and the Germans come here they are special nights to look forward to.
"We've played five games, have kept four clean sheets and the only team to score against us are the world champions.
"We've scored 10 goals at home so there are a lot of positives in this campaign."
O'Neill pronounced himself pleased with every aspect of his side's play against Norway, hailing it as "a fantastic performance".
"Every player we used, the 11 that started and the three that came on, I couldn't have asked any more. To a man, they were fantastic," he said.
"It was a very competitive game and Norway played very directly so we had to deal with that.
"We have three top-class centre-halves of real Premier League quality and we just looked very strong.
"Conor McLaughlin and Stuart Dallas gave us a great shift down the sides and Chris Brunt showed his quality in midfield, while Steven Davis led from the front as captain, as he always does."
Northern Ireland suffered a scare in the first half when Gareth McAuley sustained an injury but the West Bromwich defender was able to stay on the pitch.
"Gareth got a bad knock but if he had come off, it would probably have meant us changing our system, which ideally we didn't want to do," added the NI boss.
"We had one or two other bumps and bruises but we competed fantastically and played some very good football as well."


An American woman with a home video camera filmed an amazing wildlife rescue.

26 June 2012 Last updated at 10:20 BST
Sound a bit average? Well, the wildlife she filmed was in her own garage.. and it was a baby bear with attitude!
The furry friend got trapped in the garage after the automatic door had gone down.
Then big mummy bear came to the rescue, cleverly opening the sliding door and growling at the naughty cub.
And then the cub managed to climb back down using a ladder against the wall!

Colchester United have signed Rekeil Pyke on loan from Huddersfield Town until the end of the season.

The 19-year-old forward has yet to play a competitive first-team match for the Terriers but did feature in pre-season friendlies against Liverpool, FC Ingolstadt 04 and Oldham in 2016.
He had a three-game loan at National League side Wrexham earlier this term.
The deal to take him to Colchester, ninth in League Two, would include the play-offs should they reach them.

Henrik Stenson says he'll take the Claret Jug skydiving if he successfully defends the Open Championship at Royal Birkdale this week.

Media playback is not supported on this device
The Swede carded a joint-record eight-under-par 63 in the final round at Royal Troon in 2016 to win The Open by three shots after an enthralling final-day tussle with Phil Mickelson.
"I don't know which is going to be harder, winning the Claret Jug again or going skydiving - that thought scares me a little bit," he said. "It won't stop me from trying though."
Stenson, 41, has relished carrying the Claret Jug around the world - he has even taken it jet-skiing - and said he was sad to hand it back to the tournament organisers.
"It had become like part of the family," he said. "It's an iconic trophy. It's been the busiest year, but also the best year in my professional career."
Stenson will partner former world number one Jordan Spieth in the first two rounds at Royal Birkdale, a player he is seeking to emulate as a multiple major winner.
"Once you win one, obviously that's off your shoulder," he said.
"I think that's pretty much what we're aiming for, a few more chances to win more major championships."
For his part, Spieth is aiming to bring an end to the streak of first-time major winners that started with Jason Day's 2015 PGA Championship win and most recently saw Brooks Koepka win the US Open.
The run of first-time winners now spans seven majors, and 23-year-old Spieth believes it underlines just how hard it is for one player to dominate.
"It's very tough to do," the American said. "You have to have a lot of things go right at the right times.
"Guys are winning younger, playing more fearless, even in major championships. I think it's going to be a very exciting time.
"You'll see a group of 10 to 12 guys over the next 15-20 years, that are going to have a lot of different competitions that come down the stretch with each other.
"It's different than one person being the guy to beat. But I think it's exciting."
England's Chris Wood, and Americans Mark O'Meara and Ryan Moore will be the first group away at 06:35 BST.
Stenson and Spieth get under way at 09:47, alongside South Korea's Kim Si-woo.


Footage showing the moment a man was fatally struck by a police horse should have been shown at his inquest, his family have said.

Swansea City fan Terry Coles died after the incident near Rotherham United's former Millmoor ground in May 2000.
An inquest in 2003 concluded the 42-year-old's death was accidental.
His family are now calling for a fresh investigation into his death, with previously undisclosed evidence to be included.
Mr Coles had travelled with other Swansea fans for the final game of the season on 6 May 2000.
But before the match started, trouble broke out between opposing fans in a narrow lane beside the ground.
The inquest at Doncaster Magistrates' Court in 2003 heard Mr Coles, who was four times over the drink-drive limit, had walked into the horse's path.
Mr Coles died after suffering abdominal injuries, leaving behind a wife and two children.
His friend John Gibbs told the BBC's Inside Out sending a police horse down the alleyway was "an accident waiting to happen."
Another eyewitness said he saw the horse being ridden "straight at Terry". Alan Roberts gave a statement to police but was not called to give evidence at the inquest, his statement was read out instead.
The inquest jury also never watched the CCTV.
Mr Coles' widow Christine said: "I actually viewed the tape. And until this day, I definitely say that the horse went directly into [Terry's] path."
An Independent Police Complaints Commission review found the actions of officers Supt Dave Turner, Chf Insp Paul Cropley and PC Dave Lindsay (who was riding the horse) was "a failure of duty".
Supt Dave Turner received a verbal warning, but no action was taken against the other two who had retired and were no longer subject to the police disciplinary code.
The family only discovered this year that Chf Insp Cropley and PC Lindsay were on duty at the Hillsborough disaster in 1989.
South Yorkshire Police said: "We are now working with the family's legal team to gain a better understanding of their concerns."
Carolyn Harris MP for Swansea East and Shadow Home Office Minister said: "Whether it is an organisation like South Yorkshire Police for the way they organised the planning for that football match, or whether it is an individual, somebody made a decision that it would be policed in such a way. "
You can see the story on BBC Inside Out Yorkshire and Lincolnshire at 19:30 on Friday 21 October on BBC One.


The Duchess of Rothesay will be in Aberdeen later to visit the new home of the Rowett Institute of nutrition and health.

Camilla, the University of Aberdeen's chancellor, will officially open its new building on the medical campus at Foresterhill.
She has been chancellor of the university since 2013.
The Rowett became part of the university's college of life sciences and medicine in 2008.
The 10,000m² building has been designed to maintain the Rowett's status as a world leader in food and nutrition research.
The institute began before WW1 as an animal nutrition research centre. Its first director was the future Nobel Prize winner John (later Lord) Boyd Orr.
Its current status in the field of human nutrition is a result of the benefactor whose name it bears.
The philanthropist John Quiller Rowett stipulated that if any of the institute's animal nutrition research was found to have a bearing on humans, it would be allowed to follow it up.
These days the focus is solely on us: what we eat, why we eat it, how we digest it and what we should be thinking about eating instead.
The new building, which involves a £12m investment by the Scottish government, is a huge improvement on the Rowett's old home at Bucksburn.
It is, inevitably, state of the art.
There is a clinical investigation unit, a metabolic research facility and a body composition suite.
The last of these is otherwise known as the Bod Pod.
Looking like a cross between a bubble car and an oversized washing machine, the Bod Pod measures what people are made of: their muscle mass and body fat.
It's where we meet Ian Gourlay, dressed for measurement purposes in only trousers and a rather natty red skullcap.
He's volunteered to take part in this trial, his 16th at the Rowett.
The best one, he says, was when he had to test a range of ready meals designed to make people feel fuller for longer.
Not only were they delicious, he lost weight.
"The worst was eating cabbage for my breakfast," Ian says.
"I had red cabbage one week, then the next week was white cabbage.
"The following week it was kale.
"I've also eaten beetroot burgers, which weren't altogether pleasant."
But he's still coming back for more.
"Some of the stuff is quite interesting.
"The alternative proteins to red meat - the faba beans, the peas, buckwheat."
Ian has been working with senior research fellow Dr Alexandra Johnstone.
She's concerned with our appetites. In her current study, it's a question of whether the right kind of breakfast will make us feel fuller longer - whether the old adage "breakfast like a king, dine like a pauper" has it right.
She offers me a choice of two breakfast trays.
On one, a high fibre cereal, a glass of orange, a cheese and tomato sandwich.
On the other, turkey bacon and boiled egg, a muffin with spread and a smoothie.
Which would keep me happy until lunchtime?
It's the high fibre, fruity one - right?
Wrong.
"The one I would choose," she says, "is the high protein one."
That's the one with the turkey bacon and egg.  Not quite a fry-up, but as one of nature's chunkier gentlemen the one I'd be more likely to have gone for in the first place.
"Because I know from my research that that's going to be particularly good at filling me up," she says.
"I'm going to have a busy morning ahead so I'm less likely to grab an unhealthy snack.
"Often we're trying to improve body composition, to help people lose body fat and maintain the muscle mass.
"We know that high protein diets are particularly effective at doing that."
So hit the protein and watch the pounds fall off? Not quite. It has to be the right kind of protein.
Balance is everything. Too much animal protein is bad news in the long term.
Dr Wendy Russell, who heads the gut health team at the Rowett, looks at what happens inside us when appetite has had its way and our digestive system takes over.
"We ran some studies that showed if we ate a diet that's high in plant protein instead of animal protein, it reduced some of the risks associated with a long-term, high-protein, animal-based diet," she says.
They ran the studies using soya proteink, but in Scotland that's not a particularly sustainable approach. Better still if we could use plant proteins we can easily grow here.
"We're looking at local sources that could be readily grown in Scotland that would benefit our food growers and producers."
So if buckwheat, faba beans and linseed start turning up in your meals you'll know where the idea came from.
The Rowett is bursting with ideas.
In the past, studies have examined rationing during WW2 and calculated the food needs of besieged cities.
Today, its researchers are trying to find out if they can influence the taste buds of babies before they are born by feeding the right types of foods to their mothers.
They've even helped develop a healthier Scotch pie.
I would tell you more but I must dash. All of a sudden, I'm hungry.
