Cameron shouldn't have been on Chris Evans

Apparently, David Cameron was down the Olympic Park on Thursday. Of course he was; he hasn't done a hand's turn for the last fortnight, instead choosing to try and photobomb the Olympics in a scratchy Team GB vest, clutching a Wenlock.

This time, though, he spent twenty minutes chuntering on on the Chris Evans show.

We know how much the Tories hate any hint of the bias at the BBC, and yet they seem surprisingly relaxed about this, despite it being a breach of guidelines. MediaGuardian explains:

The BBC has strict guidelines governing the appearance of politicians on non-news programmes, which require senior executive approval, as well as topical issues that are the subject of public debate.

Such is the level of sensitivity over the interview that the BBC is believed to have discussed internally whether to remove it from the iPlayer. It remained available at the time of publication.

"Nobody knew anything until it was too late to do anything about it. It was a huge cock-up," said one BBC insider.

Cameron was so desperate to please he even started to act like he was part of Steve Wright's posse:

Cameron read out a number of text messages from listeners in the "listener breaking news" section of the show, which included "I let my new chickens out this morning" and "On my way to pick up my new Mini".

The prime minister commented: "That's buying British, I approve of that."

Mini is a German company, Prime Minister. Remember, Thatcher flogged off most of our car industry to the private sector, Dave?

Perhaps it wouldn't have been such a disaster if Chris Evans had been anything other than a fawning patsy:

Evans, who introduced Cameron as the "prime minister of Great Britain, the ultimate Team GB", read out the newspaper headlines and asked Cameron: "They've not been bad headlines over the last 13 days, have they prime minister?"

Labour, to its credit, has kept quiet on the matter.
