A member of the European Parliament told ITV News no one in Strasbourg ever asks for paperwork in relation to his allowances and expenses.
Ukip leader Nigel Farage said he is the victim of a "smear", after a newspaper claimed that he faces an investigation into his allowances.
Nick Clegg is hoping that there are votes to pick up in being the clearest voice on the pro-Europe side of the debate.
Broadcasting watchdog Ofcom has ruled that the UK Independence Party (Ukip) should be given the same status as the Conservatives, Labour and Liberal Democrats.
Ofcom said Ukip must be treated as a "major party" in England and Wales for election broadcasts.
"We hope that all broadcast outlets will reflect on the fact that patterns of support in British politics are changing very quickly and that more and more people are supporting and voting for Ukip," the party's director of communications Patrick O'Flynn said.
The Ofcom rules state that "due weight must be given to the coverage of major parties during the election period" and there must be "due impartiality."
The Prime Minister has been accused of undermining the party's chances of winning at the next election over its immigration policy, according to the Conservative leader of Guildford Council.
In a letter to Mr Cameron, Stephen Mansbridge said that he feared the borough would lose its Tory majority for the first time in 12 years and that MP Anne Milton would be defeated at the election because of government policies.
We have lost many Conservative Party members - indeed whole branches of the local association - due to carious government policies, and Ukip won over 20 per cent of the vote in the local elections last year in Surrey.
Immigration, the EU and gay marriage are frequently given as reasons for this.
Home Secretary Theresa May has dismissed claims that the Tories need to have a clearer narrative on immigration, after former defence secretary Dr Liam Fox warned the Prime Minister he would be guilty of "complacency" if he failed to address the damage Ukip could do at the ballot box.

In all honesty, whatever the Government does to reduced the pull factors that draw people to Britain, as long as there is such an enormous disparity in terms of income per head, there will be an overwhelming incentive for people to move from poorer nations to richer states.
David Cameron must ditch the pledge to bring net migration down to tens of thousands and instead focus efforts on curbing the number of low-skilled workers heading to Britain to stave off the threat from Ukip, a former defence secretary has said.
Liam Fox warned the Prime Minister he would be guilty of "dangerous complacency" if he failed to address the damage Nigel Farage's party could do at the ballot box.
In an interview with The Sunday Telegraph, the Eurosceptic called for the party to drop the "statistical nonsense" and develop a "clearer narrative" on immigration.
Dr Fox said: "If the Tories are to bring back enough of these voters to win an overall majority at the election, then there needs to be a clearer narrative on immigration, stressing not only the need to restrict numbers, but also to determine which individuals, with what skills enter our country."

Farage in optimistic mood again - suggesting that UKIP could hold balance of power after general election
Farage says post 2015 he would do a deal with the devil to get a referendum
Ukip leader Nigel Farage is due to hold a public meeting in Torquay this morning, after the party conference yesterday, in which he said he would resign as leader if his prediction of winning several seats in the next General Election does not come to pass.
Ukip's Nigel Farage has said he will resign as leader of the party if his prediction of winning several seats in the next General Election does not come to pass.
In his main address to conference goers in Torquay, Mr Farage said he believed seats in the Commons in 2015 were achievable if the eurosceptic party clears its next hurdles in European and local council elections this May.
Asked about his comments at a press conference, Mr Farage said: "I said in my speech we could get several MPs, or a good number of MPs, in Westminster in 2015 provided, and I made it absolutely clear, that would not happen unless we clear this hurdle effectively on May 22.
"I stand by that, this is the election Ukip has waited 20 years for... I would have thought so [resign] ... good lord yes, I would be out the door before you could say Jack Robinson."
Ukip's campaign director Neil Hamilton is a "back room boy", Nigel Farage has said, despite the former Tory MP being given a 30 minute speaking slot at the party's spring conference.
Mr Hamilton, was implicated in the 1990s cash for questions scandal. He is thought to be on Ukip's approved list of possible Parliamentary candidates at next year's election - but is not running for a seat in the European Parliament.
Mr Farage said: "He's the back room boy, he's the campaign manager... When it comes to claims from journalists about what he did or did not do, I generally find... I remember being told he was convicted of something, which I don't believe he was."
Ukip leader Nigel Farage has said he felt "awkward" on a recent journey in central London when he heard only foreign languages spoken by passengers on a train.
When he was asked about immigration at a press conference during Ukip's spring conference in Torquay.
He said: "I got the train the other night, it was rush hour, from Charing Cross, it was the stopper going out. We stopped at London Bridge, New Cross, Hither Green.
"It wasn't until after we got past Grove Park that I could actually hear English being audibly spoken in the carriage.
"Does that make me feel slightly awkward? Yes.
"I wonder what's really going on. And I'm sure that's a view that will be reflected by three quarters of the population, perhaps even more."
