Comedian Eddie Izzard confirmed plans for a future career in politics today as he met Gordon Brown after completing 43 marathons in 51 days.

The 47-year-old posed with the Prime Minister and Sarah Brown outside Number 10 to mark his achievement.

Political plan: Eddie Izzard wants to become a MP or MEP

He finished the 1,100-mile-plus run at London's Trafalgar Square yesterday in pouring rain. Today, Foreign Secretary David Miliband also stopped in on Downing Street to congratulate Izzard.

The comic said: "I've said I will stand as an MP or MEP at some stage in 10 to 15 years, I like to make long announcements. But at the moment I've spent so long trying to get my career going I don't want to throw it away."

He put his running success down to "relentlessness" and said he felt good after the seven-and-a-half week challenge.

He went on: "I've made it back, I think psychologically stopping has been good so I feel okay. I feel really good. My legs hurt, my body hurts, I'm very tired. I lost my toenails, had blisters and stuff, but to finish, it's kind of like science fiction in a way."

Izzard, previously better known for his surrealist sense of humour than athletic ability, added: "I just had to keep going, I just get determined to do strange things."

The double Emmy Award winner said he will carry on clocking up the miles.

"I do have to wind down but I want to keep a couple of long runs going a week, I don't want to throw it all away."

Holding the four flags he took on his epic trip - English, Welsh, Scottish and a "made up" one for Northern Ireland featuring a peace dove - he said all the running has not made him lose weight: "You put on weight because of the muscle, but I've changed shape."
