Asked about his recent difficulties, including axing the 10p tax rate and arguments over public sector pay, Mr Brown said: "I will not hesitate to take these long-term decisions. That's what being in politics is about.
"Of course sometimes it is unpopular in the short term. Sometimes you might get no temporary advantage out of what might be the right long term thing to do."
But he insisted: "We're taking all the measures that we can and we will not be diverted from this as a fundamental priority."
He said he recognised that "we've got to show people who are worried about their homes and people who are worried about their mortgages and people who are worried about their jobs that we can ensure that the economy is safe for them over the next few months."
