David Cameron has been caught on microphone making fun of people from Yorkshire

David Cameron has been caught on microphone making fun of people from Yorkshire.

The Prime Minister was rehearsing a speech in Leeds when he made the joke, not realising the microphone was switched on.

He was recorded telling a group of colleagues: "We just thought people in Yorkshire hated everyone else, we didn't realise they hate each other."

It's not the first time the Prime Minister has slipped up thanks to an unexpected microphone.

Last year he was recorded telling the former New York mayor that the Queen "purred" down the phone to him when she heard the result of the Scottish referendum vote.

Gordon Brown's 2010 election campaign was also famously derailed when he was caught on mic calling Rochdale grandmother Gillian Duffy a "bigoted woman" when she raised concerns over immigration.

David Cameron was practising his speech about stepping up local devolution in Yorkshire when he made the comment.

The full conversation went:

David Cameron: "I'll say… delighted there’s been such a strong response. Time to look at all the proposals that have been made. Obviously the more politicians can come together locally to come up with preferred solutions the better. But one way or another…"

Unidentified man: "The fact is there will be some devolution coming to Yorkshire, but what form that takes…"

David Cameron: "We just thought people in Yorkshire hated everyone else, we didn’t realise they hated each other so much."
