Prime Minister Gordon Brown struck a defiant note on Thursday in the face of his growing unpopularity, saying he was focused on keeping the economy on an even keel with the right long-term decisions.
While he is on a three-day tour of the United States, Brown's poll ratings have fallen sharply at home and there is a growing sense of a government under siege as Britons fret about their well-being because of falling home prices and a slowing economy as a global credit crunch takes its toll.
The Labour Party, in power for more than a decade, is facing a drubbing in local elections on May 1, raising speculation he might face a challenge for the leadership before the next national election, which must take place by 2010.
"I'm sticking to the job and I'm getting on with the job," Brown said, brushing aside a question on his problems at home at a White House news conference with President George W. Bush.
Worried about their own future, many Labour lawmakers are unhappy with Brown's decision last year to abolish a 10 percent tax rate that benefited low earners in order to make a cut in the main rate of tax from 22 percent to 20 percent.
A Labour member of the House of Lords led the attack on Thursday. He was quoted as saying in a newspaper interview that senior members of the government were now turning their minds to who can replace Brown, who took over from Tony Blair last June after a decade as Chancellor.
Then Angela Smith, a junior member of Brown's government, was reported to have quit, only to say later she had talked to the prime minister and was not resigning after all.
Adding to Brown's woes, veteran Labour MP Gwyneth Dunwoody - the longest-serving female member of parliament - was reported late on Thursday to have died, which will force a by-election.
Asked about anger over the abolition of the 10 percent tax rate, Brown made it clear he was not about to roll back.
