Nigel Farage is to stop giving interviews with the BBC after he declared war on the broadcaster.

The Ukip leader has pulled out of an interview with BBC Radio 1 after he accused the corporation of being biased against him.

But sources admit the boycott will not include planned appearances on some of the most popular TV and radio shows.

A party source said: 'We will no longer be collaborating with the BBC between now and the election unless their coverage of Ukip changes drastically.

'We have said we are at war with the BBC and we mean it.'

But the source said Mr Farage would still take part in a BBC debate tonight, interviews on BBC Radio 4's Today programme and BBC Radio 2's Jeremy Vine show tomorrow, and the Andrew Marr show on BBC One on Sunday as they were 'long-standing' commitments.

During a campaign visit to Aylesbury today, Mr Farage said: 'I have no complaints about the other broadcasters. They have abided by the Ofcom ruling.

'But we have this bizarre state of affairs where we have BBC, an organisation which we are all charged £145 a year to have the benefit of seeing, aren't regulated by Ofcom and made their own minds up and frankly produce the News at Ten every night as if there are just two choices in England.

'I think they have been biased and last night's report about South Thanet frankly was outrageous.'

He also hit out at the make-up of the audience for tonight's BBC Question Time debate, and suggested that members had to be members of the Socialist Workers Party to get in.

The audience will be a quarter Tory, a quarter Labour, a quarter Lib Dem and a quarter undecideds. The three main party leaders are being quizzed separately from 8pm to 9.30pm.

Mr Farage will face a different audience for a separate question and answer programme at 10:50pm.

Mr Farage said: 'We'll see what we get tonight but I do know is the real audience will be sitting at home and tonight I will do my best to tell the truth, even though at times, the truth is difficult to hear.'

Asked whether he was submitting a formal complaint about the BBC coverage, he said: 'Talk to my lawyer.'

The BBC confirmed that Mr Farage had pulled out of a 'Live Lounge' debate with young people to be hosted by Radio 1 tomorrow evening.

A spokesman said: 'We’re hoping to interview an alternative from Ukip at a later date.'

The BBC was accused of launching a Left-wing stitch-up on David Cameron when he took part in the debate series earlier this month.

The Conservative party leader was repeatedly interrupted while trying to answer questions.

Host Chris Smith was also accused of being hostile towards the Prime Minister, at one point offering to bet £1,000 that he would not win a majority.

Mr Farage last night reported the BBC to police over a joke, claiming it had broadcast false information that could damage his election chances.

During Have I Got News For You on Friday, journalist Camilla Long said she'd spent more time in South Thanet than its would-be MP.

Mr Farage, who said he had held more than 20 public meetings in the constituency since January and has a residence there, said it was a 'blatant' breach of electoral law.

Kent Police confirmed that it had received the complaint, but said no action would be taken.

A Ukip spokesman today said: 'The BBC's coverage of this election has been so biased against UKIP that we are having to be extra selective of what we use Nigel's time for.
