- Latest YouGov projection – Conservative 311, Labour 255, Liberal Democrats 10, SNP 51. (YouGov)
Wednesday May 31
5.30pm Jeremy Corbyn is getting ready to take part in the BBC debate later. But Theresa May is still refusing to take part.
5pm: YouGov today updated its election result projection which shows that the UK is heading towards a hung parliament. WHAT IS A HUNG PARLIAMENT?
The latest projection puts the Conservatives at 311 seats, just below the 326 seats needed to get a majority in the House of Commons.
YouGov founder Stephan Shakespeare said: “Currently our model is showing the Conservatives set to take 311 seats and Labour 255, the SNP on 51 and the Liberal Democrats on 10, putting us on hung parliament territory.
“However these are just the midpoints and, as with any model, there is leeway either side. For example, the Tories could end up with as many as 344 and Labour as few as 227 – leading to an increased Conservative majority.”
The Tory campaign was rocked this morning when the Times published the first YouGov projection using its new model.

3.30pm: Theresa May has defended her decision to refuse to take part in the TV debate by saying that she is answering questions from voters on the campaign trail.
“I think debates where the politicians are squabbling among themselves doesn’t do anything for the process of electioneering," she said.
"I think it’s about getting out and about, meeting voters and hearing directly from voters.”
1.49pm: Speaking at an event in Bath, Theresa May said that unless people vote for the Conservatives, they are voting for Jeremy Corbyn to become Prime Minister of a hung parliament.
1.30pm: The Conservative Party has said that “there are no changes to the Prime Minister’s plans” regarding tonight’s debate.

In a statement, Jeremy Corbyn said: “I will be taking part in tonight’s debate because I believe we must give people the chance to hear and engage with the leaders of the main parties before they vote.
“I have never been afraid of a debate in my life. Labour’s campaign has been about taking our polices to people across the country and listening to the concerns of voters.
“The Tories have been conducting a stage-managed arms-length campaign and have treated the public with contempt. Refusing to join me in Cambridge tonight would be another sign of Theresa May’s weakness, not strength.”
1.15pm: Lord Ashcroft has launched a new seat-by-seat poll which uses the MRP model – the same model which YouGov used to predict a hung parliament.
But Lord Aschcroft’s poll predicts a Tory majority of 142. He put the Conservatives on 396 seats, Labour on 180, the SNP on 47 and the Liberal Democrats on six.
General election polls latest: Jeremy Corbyn reveals he will take part in the TV debate
12.20pm: Jeremy Corbyn has confirmed that he will appear in tonight's BBC debate and challenged the Prime Minister to go head-to-head with him.
He said: “It’s very odd that you have an election campaign where we go out and talk to people all the time and the Prime Minister seems to have difficulty in meeting anyone or having any debates.
“There is a debate in Cambridge tonight, I invite her to go to Cambridge and to debate her policies, debate her record, debate their plans, debate their proposals and let the public make up their mind.”
Leaving the rally in Reading, he added: "I have to go now because I'm going to Cambridge to get ready for the debate tonight because there is no hiding place.
"We'll put our views out there and let the public decide."
Noon: Jeremy Corbyn has taken to Twitter to challenge Theresa May to “come and debate me – any time, any place”.
The Labour leader tweeted: “Britain deserves to see the only two people who could be the next Prime Minister debate.”
Mrs May has refused to take part in tonight’s seven-way leaders’ debate on the BBC, sending home secretary Amber Rudd in her place.

11.08am: Jeremy Corbyn has refused to rule out an informal pact with the SNP that could keep the Conservatives out of government in the event of a hung parliament.
Mr Corbyn has previously said that he would not enter into a coalition with the SNP, but following today’s YouGov poll, questions have been raised about a potential “confidence and supply deal”.
Such a deal could see the SNP backing a minority Labour government in House of Commons votes on motions of confidence and legislation which authorises the government to spend money.
10.30am: YouGov has clarified the polling methods used in its latest release, which predicts a hung parliament.
Pollsters interview around 7,000 people every day about their voting intentions, which over a week boils down to around 75 voters per constituency.
This data is used to create a model which estimates the way in which probability that a voter with specific characteristics will vote.
Using information from the UK Office of National Statistics, the British Election Study, and past election results, YouGov then estimates the number of each type of voter per constituency, and combines this with the date to produce a result.
This method of polling consistently predicted that Leave would beat Remain in the EU referendum, and that Hillary Clinton would win the popular vote in the US presidential election, but that midwestern battleground states were too close to call.
10.01am: Jeremy Corbyn says that Theresa May’s comment that he would be “naked in the negotiating chamber” was “inappropriate”.
The Labour leader says that he would approach Brexit negotiations seriously, but would not threaten Europe.
Shadow health secretary Jonathan Ashworth says that Labour would put more money into social care. He adds that the £72,000 proposed cap is “sound”, but says that Labour would consult on the plans.

9.52am: Theresa May claims that Labour wants “uncontrolled migration”.
Speaking in Plymouth, she said: "What we need to do is have proper control of our immigration and, of course, we are going to be able to put in rules for people coming from the EU to the UK once we leave the European Union.
"I want to ensure we are controlling migration because too high uncontrolled migration puts pressure on our public services but it also lowers wages at the lower end of the income scale.”
Mrs May was referring to The Telegraph’s front page, which reports that a leaked policy paper shows “Labour’s secret plan to increase migration”.
The paper reportedly proposes bringing back a special visa scheme for people seeking "low-skilled, unskilled and seasonal work" in the UK.
Jeremy Corbyn says that the document was one discussed by researchers, and that Labour’s policy can be found in its manifesto.
He adds that free movement would end when the UK leaves the EU, and that Labour will not make false promises about immigration, as Mrs May “is doing now”.
Jeremy Corbyn speaking at a campaign event
9.41am: Theresa May has dismissed the recent poll which points to a hung parliament.
Speaking in Plymouth, she said: "The only poll that matters is the one that's going to take place on June 8 and then people will have a choice as to who they want to see as leader, who they want to see as prime minister taking this country forward in the future, me or Jeremy Corbyn.
"I have the plan for the Brexit negotiations but I've also got a plan to build a stronger and more prosperous Britain and I'm confident we can do that because I believe in Britain and I believe in the British people."
9.35am: Shadow health secretary Jonathan Ashworth is now speaking at the Labour event.
He says that the Conservatives wanted to gloss over public services, but the public want proper answers.
He adds that Jeremy Hunt said that the Conservatives would promise an extra £8 billion for the NHS, a claim rejected by the Institute for Fiscal Studies.
The funding crisis has left the NHS weak, Mr Ashworth adds, pointing to the recent cyber attack as an example.
9.20am: Jeremy Corbyn is holding a press conference on the NHS and schools, which he says are “anything but strong and stable”.
He is attacking Conservative tax cuts and austerity, reminding the audience that Labour will invest in public services and give public sector staff a pay rise.
Those attending the conference have been given a 36-page document recapping the current government’s public services record.
One passage reads: “New analysis of the Tory threat has revealed that if the current rate of deterioration under the Tories continues, by 2022 our health and education services could be facing huge problems. It could mean:
“In a Tory NHS and social care system:
“5.5 million people on waiting lists in England, 1.8 million more than at present.
“Almost 1.5 million older and vulnerable people with unmet social care needs.
“In a Tory education system:
“650,000 pupils crammed into primary classes of over 30.
“Families left almost £450 worse off per child as a result of the Tories’ plan to scrap free school meals for 1.7 million children.”

9.00am: A shock new poll has predicted a hung parliament, with Theresa May set to lose her parliamentary majority.
It puts the Conservatives on 310 seats – 20 less than they currently have and 16 short of a majority. Labour is on 257 seats – 28 more than it currently has, the SNP is on 50 seats – a loss of four and the Liberal Democrats are on 10 seats, down one.
The YouGov/The Times poll is the first to give a seat-by-seat estimate of the final result and allows for a wide margin of error.
If the prediction is accurate, it will be a major disappointment for Theresa May, who called for the election to “strengthen her hand” ahead of Brexit negotiations.
The pound fell sharply to a low of $1.279 against the dollar and €1.144 against the euro after the poll was released last night due to the uncertainty a hung parliament would produce.
Labour will announce who will represent the party on tonight's BBC leaders' debate later this afternoon.
Jeremy Corbyn has previously said that he will not take party in any debates without Theresa May, however there is speculation that he could make a surprise appearance buoyed by his recent round of successful TV appearances.
The Conservatives will be represented by Amber Rudd, after Mrs May refused to take part.
Mr Corbyn was interviewed on BBC’s The One Show last night and was praised for his warm, “human” appearance.
The Labour leader spoke about his love of gardening and his part in the fight against apartheid.
He appeared alone, without his wife Laura Alvarez. Mrs May was joined by her husband Philip when she appeared on the chat show earlier this month.
Earlier in the day, Mr Corbyn suffered a set-back when he stumbled over the cost of Labour’s plan to offer free childcare during an interview on BBC Radio 4’s Woman’s Hour.
He later defended presenter Emma Barnett’s right as a journalist to hold him to account, and condemned the antisemitic abuse later directed at her.
Theresa May spoke about Brexit at a campaign event in Wolverhampton, and claimed that Mr Corbyn would be “naked in the negotiating chamber” if elected as Prime Minister.
