David Cameron brushes off criticism from Tennant

Mr Cameron said he had not watched much of David Tennant's Doctor Who series

Conservative leader David Cameron has brushed off the news that Doctor Who star David Tennant is not a fan of his.

Mr Cameron told BBC Radio 5 live: "You can't win them all, can you?"

He admitted he had not watched much of the recent series of the long-running programme, saying he grew up with Jon Pertwee and Tom Baker as the Doctor.

Outgoing Doctor Who star Tennant, a Labour supporter who appeared in a 2005 party political broadcast, had said he would prefer Mr Brown to stay as PM.

Tennant's four-year stint as the Doctor came to an end in the New Year's Day special - which was watched by more than 10m people.

Well that's a pity, but there we are David Cameron on hearing the news

The show has been going for 46 years - in 2006 it was named the longest running TV sci-fi show by the Guinness Book of records

Mr Cameron said he had not watched much of Doctor Who since his own childhood - when other actors played the role of the Doctor.

He told the Richard Bacon show: "I'm so old I'm sort of Jon Pertwee country, and a bit of Tom Baker. I watched the Christmas one but I haven't refreshed myself all the way through so I've got a bit out of touch."

Told that Doctor Who was not a fan of his, Mr Cameron replied: "Well that's a pity but there we are."

He added: "You're never going to win over everybody. I definitely believe there's no point trying to win over everyone.

"Say what you think, say what you believe in, say what you believe needs to be done and if people will come with you they will come with you."

He added: "I never give up so maybe I'll have another go at convincing him."
