Gordon Brown has come clean about his favourite biscuit -- after ignoring questions on the subject during a recent live web chat.

The Prime Minister had been willing to talk with users of Mumsnet about a range of subjects in the promotional web chat.

He spoke about the government's record on families, swine flu and expenses as well as his own personal health.

But he repeatedly dodged (or should that be Jammie Dodger-ed) to favourite biscuit question - along with Paxman-esque follow-ups about his dunking activities.

But over the weekend he used Twitter to reveal that he was a fan of any chocolate coated biscuits… thus drawing himself into the Jaffa Cake cake or biscuit debate. We await a Tory response.
