Russell Brand has backed backed the Labour leader Ed Miliband just days before the general election.
Speaking on his YouTube channel, he said: "You've got to vote Labour.
"David Cameron might think I’m a joke, but I don’t think there is anything funny about what the Conservative Party have been doing to this country and we have to stop them."
Green Party leader Natalie Bennett has said that Britain must do "must do more for people fleeing violence".
Labour leader Ed Miliband has said the NHS is "in grave danger and fighting for its life" because of the choices of the coalition government.
Mr Miliband, who was speaking in Brighton where he was joined on the campaign trail by Shadow Chancellor Ed Balls and celebrity chef Delia Smith, urged the electorate to vote for his party so that it can "rescue the NHS".
David Cameron has accused the Liberal Democrats of "desperation" over claims made by a peer that the Prime Minister told Nick Clegg in private that he did not think the Conservatives would win a majority.
Mr Cameron responded to Lord Scriven's claims during a campaign visit this morning to the marginal Hastings and Rye constituency.
Speaking on the BBC, Lord Scriven said Mr Clegg told him of Mr Cameron's view shortly before Parliament was dissolved in March for the General Election.
He said he had decided to speak out after reading a report in the Daily Telegraph that the Tories were targeting a series of Lib Dem-held marginals which they believed held the key to a Conservative victory.
I don't take back anything I said in the tweet. People are not stupid. The opinion polls show what's happening, the private opinion polls show what is happening.
When I read what's on the front page of the Daily Telegraph, that David Cameron is not telling the truth to try to scare people to vote, then I think that his private feelings do need to be made clear.
Conservatives have reacted with fury to Liberal Democrat claims that David Cameron has admitted privately that he cannot win a majority at the General Election on Thursday.
Lib Dem peer Lord Scriven has said the Prime Minister told Nick Clegg in private that the Tories would not get an overall majority.
Conservative aides said the claim was "100% untrue" and "complete nonsense" and showed that the Lib Dem campaign was in a state of panic.
Writing on his Twitter feed, Lord Scriven accused Mr Cameron of "lying" about the number of seats the Conservatives need to win a majority.
So Cameron has taken to lying on Tory Maj. @nick_clegg told me that Cameron privately admitted to him that the Tories won't win a majority
A Conservative spokesman said: "This is 100%, definitely not true. The Prime Minister has repeatedly made clear we only need to win 23 seats to get a majority and he is totally focused on winning that majority."
The Labour leader has claimed that David Cameron is a 'desperate man' who has 'lost the arguments'.
Speaking to the Today programme, Ed Miliband said: "Frankly I think David Cameron is a pretty desperate man.
"He is a desperate man because what he is reduced to is trying to set this election up as a clash of two nations. He has lost all the arguments.
"He has lost the argument about the economy. He has lost the argument about leadership, he has lost the argument about his broken promises on the NHS. So this is all he has got left. It isn't a clash of two nations. It's how you stand up for working people in England, in Scotland, in Wales, in Northern Ireland. In every part of our country."
Ed Miliband has said the Labour party will not negotiate with the SNP after the General Election.
Speaking on the Today programme, the Labour leader said: "Are we going not going to negotiate about our Queen's Speech, no. We are not going to negotiate with the SNP.
"I am going to put a Labour Queen's Speech before the House of Commons. I want to put a Labour budget before the House of Commons."
The Labour Party leader Ed Miliband has said voters face a "huge choice" when the country goes to the ballot box on Thursday.
He told the Today programme: "There is a huge choice between a country run by the richest and most powerful, if we have a continuation of a Conservative Government, or a Labour Government which will put working people first."
