The Guardian's Rafael Behr tells The Westminster Hour he does not think behind the scenes talks have already taken place between Labour and the SNP "for the simple reason that the fear of such a thing being revealed would be so intense".

It would be the same for Labour and Liberal Democrats, he claims.

Philip Cowley, of Nottingham University, says that, if the SNP do help to put Labour in power after the election, "without some sort of deal they will just make life hell on a week in, week out basis".

Spectator assistant editor Isabel Hardman raises the matter of English votes for English laws. "I don’t think the West Lothian question has been answered and I think it will be asked again quite soon after this election," she says.

BBC Radio 4

BBC Radio 4's the Westminster Hour hears the views of its regular panellists on how the election campaign is going so far.

Guardian political columnist Rafael Behr says: "Of the campaigns, it's still the Conservatives who don't seem to be as assured in the footing that they’ve got, certainly as they were expecting to maybe a couple of months ago."

But Isabel Hardman of the Spectator argues that "the fundamentals are still in [the Conservatives'] favour" - with the SNP "advancing in Scotland" and David Cameron more trusted on the economy."

Philip Cowley of Nottingham University, adds that "Ed Miliband's ratings are going up, not down" while the situation in Scotland will not benefit the Tories.

Commenting on the letter from Lib Dem election campaign chief Lord Ashdown about Nick Clegg and last week's opposition leaders' debate, a BBC spokeswoman says: "We have received the letter today and will respond in due course."

Lawyers for Nigel Farage will write to the BBC Trust next week and demand to know "the logic" behind the choice of polling company who helped pick the audience at last weeks TV leaders' debate.

The UKIP leader criticised the BBC during the debate and labelled the audience "left wing". Presenter David Dimbleby told him: "This is an audience that has been carefully chosen, not by the BBC but by an independent polling organisation to represent the balance between all parties."

Speaking on the campaign trail in Ash, Kent, Mr Farage said he will ask the BBC to "tell us the logic behind giving a polling organisation with a history of getting UKIP wrong...why on earth were those people chosen?"

He added that he also wants to ask "what assurances can you give us that for the rest of this election campaign there is going to be free and impartial treatment?"

Asked if he still planned to appear in the final televised leaders' event which is due on the BBC in the last week of the campaign, Nigel Farage said "very much so".

Speaking last week, before the BBC "challengers' debate", Lib Dem leader Nick Clegg said: "I know, of course, David Cameron didn't want to be part of the debate but I don't see why I should have been prevented from being part of that debate and speaking up for what we've done in coalition if he doesn't want to do it."

A BBC statement on 16 March said: "As part of a package that the broadcasters and political parties agreed on, tonight's debate is for opposition leaders, and the Conservatives and Lib Dems are not included."

The Liberal Democrats have written to the BBC's director general to complain it misrepresented the party's position by reporting that Nick Clegg opted out of last week's TV debate.

The debate featured the leaders of five opposition parties but the Conservatives and Lib Dems were not represented.

In a letter to the BBC's director general Tony Hall, the party's election campaign chief Lord Ashdown wrote:
