David Cameron will likely be squirming this morning, after his uncle claimed that the working classes "prefer to be led by a duke".
The prime minister's constant efforts to get past his privileged Etonian background were dismissed by Sir William Dugdale, the Second Baronet married to the prime minister's maternal aunt Cecilia.
"The thing is, and the Labour party underestimate it, but, if you ask the working classes who they want to lead them, they prefer to be led by a duke," he told the Telegraph at the launch of his memoirs in Mayfair.
"I know it's an unpopular thing to say these days, however I have learnt this from my own experience."
He was also scathing about attempts to disassociate leading Conservatives like Mr Cameron and George Osborne, from images of their Bullingdon Club days in Oxford.
"Well, its so silly," he said. "You can't just turn up to things in an open-necked shirt.
"So many of the clubs in Oxford required you to wear white tie. You have to have a bath before you go to things and not just turn up in your bovver boots."
Sir William was not a member of the club but said he joined its members in protests against trade unions.
