Cameron asked: 'How many jobs should an MP have?'

The prime minister was given one of the shortest questions in PMQs when Labour MP Phil Wilson asked him: "How many jobs should an MP have?"

David Cameron said the House of Commons benefited from MPs with outside interests - referring to former Labour ministers David Blunkett and Jack Straw.

He excluded his predecessor Gordon Brown, but Mr Cameron said "there are honourable members opposite who do give good service to this House".
