LONDON - British Prime Minister Gordon Brown fought to hold on to his job Thursday in a debate against the two men who hope to replace him, David Cameron of the Conservative Party and Nick Clegg of the Liberal Democrats.

But he lost the debate decisively, according to two snap polls.

Cameron came first in both polls, with Clegg second and Brown third.

But the debate performances do not seem to have changed voters' minds about whom to back, according to one poll.

Just over a third of voters say they favor the Conservatives, and the same number back the Liberal Democrats, according to the poll by ComRes for ITV News. Just under one-quarter prefer Labor, the poll suggests.

Those numbers are essentially unchanged from the results after a similar debate last week.

In this week's debate, Brown repeatedly insisted that Cameron represents "the same old Conservative party," which would take money out of the economy for "ideological reasons."
