PRIME minister Gordon Brown insisted today that he will serve another five years if Labour wins the general election.

Earlier this week business secretary Lord Mandelson raised the prospect that Mr Brown might not complete a full term as leader of the country if his party triumphs on May 6.

But Mr Brown said today: "I will be standing for the next five years. I’m here with one purpose - to serve my country, it’s the only thing I want to do."

However, the Prime Minister added that he could cope with life outside politics. He said: "Of course, I’ve written half a dozen books, I’ve done speeches about things other than politics. I’m fascinated by other issues. But I’m here to win."

The Prime Minister's comments come after Lord Mandelson said Mr Brown may serve "five more years, or four, or three".
