What kind of Labour MP had never heard of Damian McBride until Smeargate?

Guido flags up the news that Damian McBride is facing expulsion from the Labour Party. His local MP, Rudi Vis, has said that he supports expulsion and that he has “never even heard of [McBride] before”. Now, I’m sure some Coffee Housers will be applauding Vis, who has been the MP for Finchley and Golders Green since 1997 and is standing down at the next election, for having kept his distance from McBride. But it strikes me as almost negligent for an MP to support someone for leader of their party without knowing anything about the people they surround themselves with. If you want to understand who Brown is, look at who he chooses to have work for him.
