He said he had gone 'off script' with the remark adding: 'I suppose it's just the campaign. By the time you have made as many speeches as I have on this campaign all sorts of funny things start popping out of your mouth.' Mr Cameron likened himself to the Green Party leader Natalie Bennett, who infamously blamed a 'brain fade' after a disastrous interview. He said: 'I had what Natalie would describe as a brain fade – I don't know what happened to me. I think I was overcome by something. But these things sometimes happen when you're on the stump.' Labour said the gaffe exposed the Prime Minister as a 'phoney'. Former Downing Street spin chief Alastair Campbell claimed it 'says a lot about his character', adding: 'Out of touch. Phoney. Believes nothing.' Shadow chancellor Ed Balls, a Norwich City fan, tweeted: 'Hey David Cameron... I'm off to see that football team I support this afternoon. Name escapes me... they play in yellow... Watford?' Mr Cameron has been pictured watching football with his son Elwyn - but admitted that he does not go to live games very often .

David Cameron said he started supporting Aston Villa because his uncle was 'involved in the club'. In fact, the Prime Minister's late uncle Sir William Dugdale was Aston Villa's chairman from 1975 to 1982. In the final year of his chairmanship, Villa beat the odds to win the European Cup. Mr Cameron said he remembered the glory days back in the early 80s'. He said the star players Andy Gray and Brian Little 'got me going'. But Mr Cameron, interviewed by Sky News host Dermot Murnaghan, said: 'My uncle was involved in the club and back in the early 80s and all those successes - Andy Gray and Brian Little got me going. 'I don't go very often - in fact I haven't been for years and years - but I do try to keep up. We're going to escape the relegation zone, which we're out of now - and the cup final is very exciting.' Mr Cameron's late uncle Sir William Dugdale was Aston Villa's chairman from 1975 to 1982. Reminded of his comment in 2001 in the House of Commons that he wasn't actually a football fan, Mr Cameron said: 'I mean, I'm not a regular attender, I used to play football as a kid, my son plays football, and I try and sort of keep up with what's happening in the Premier League and see how Villa are doing. 'But when they get snug in the middle of the table I tend to sort of, I tend to back off a bit. When we get close to the bottom I get nervous, but I don't know what happened.' Mr Cameron was asked to show his support for Aston Villa by naming the year of the club's famous European Cup final victory in 1982. The PM said: 'It was early 80s, I'm not going to give you a date because I'll get it wrong.' He added: 'I'm not doing quiz time because I will get them all wrong.' Mr Cameron made the gaffe in a speech on multiculturalism in the UK – claiming it was possible to support a number of teams at the same time and still be British. He said: 'You can support Man United, the Windies and Team GB all at the same time.' But he then added: 'Of course I'd rather you supported West Ham.' Speaking on the Murnaghan programme broadcast this morning, Mr Cameron tried to explain away the gaffe. He said: 'I've been an Aston Villa fan all my life, I literally opened my mouth and I was going off-piste about the fact that in Britain you can be a supporter of the West Indies, a supporter of Manchester United, and a supporter of Team GB.'
