Gordon, Ken & PMQs

Just listening to Prime Ministers Questions. For the second week in succession the PM did not refer to Ken Livingstone directly when responding to a question about London. Last week he endorsed "a Labour mayor" but didn't mention the present Labour mayor by name. Today, in response to a question about policing from Labour MP Andrew Dismore, he endorsed the present "administration" in London. Keeping his distance, wouldn't say? Mind you, they've never really got on.
