Livingstone: Boris can't help himself on race

Mr Livingstone said: "He's not a racist in the sense that anyone would make that point, but he shouldn't have written that crap. He can't help himself.

"Apparently when he meets foreign mayors with distinctive language patterns, he mimics them almost as soon as they are out of the bloody door.

"He doesn't mean it in any unpleasant way, but it is very easy for people to misinterpret that."
