Economic storm not over: PM Brown

And in a pre-election swipe at his political rivals, he said "now is not the time to turn back", adding: "I will not let you down".

He also said the Budget would be held on 24 March and confirmed a pay freeze on senior public employees.

The Tories say Labour cannot be trusted as it presided over a deep recession.

They say a new "economic model" is needed to replace an economy burdened by public and private debt and have called for action to cut the ballooning deficit to begin straight away after the election - expected to take place on 6 May.

The Lib Dems say the economy is too fragile to start cutting public spending and government support for business and jobs must continue.

`Risk`

Revised figures published in February showed the UK emerged more strongly from recession at the end of last year than had previously been thought, but some economists have warned that growth could easily falter again in the coming months.

Mr Brown said the worst of the recession was over but the economic recovery remained "fragile" and could be undermined if spending cuts were pushed through too quickly.

"While we have come through the worst of this dreadful storm, the waters are still choppy. There are still real risks to the recovery."

He warned that "recklessly and rapidly" withdrawing the government support put in place after the financial collapse of 2008 would "risk driving our economy back into recession".

But he also urged discipline in public sector pay, announcing a pay freeze on senior public servants such as NHS managers, top civil servants, judges and military leaders and the pay of consultants, GPs and dentists.

He said that combined with the measures announced in December this would save 3bn pounds by 2013/14.

The prime minister warned of further economic risks ahead and said equally tough decisions would be needed as those taken by Labour at the height of the 2008 financial crisis.

"We have got through this storm together, but there are still substantial risks ahead, there will be bumps in the road and I believe the only way to overcome them is by displaying the same strength and resolve that we did during the crisis and I will not let you down."

`Character`

Speaking at the same London venue where David Cameron attacked Mr Brown`s economic policies last week, Mr Brown mounted a thinly veiled attack on the Tory leader, who has sought to make character an election issue.

"I believe that character is not about telling people what they want to hear but about telling them what they need to know.

"It`s about having the courage to set your mission and the courage to take the tough decisions and stick to them without being blown off course, even when the going is difficult.

"With me what see is what you get - and the stakes are high, we dare not risk the recovery for our task above all else is to preserve and expand the jobs and lift the standards of life of the British people.

"We are weathering the storm. Now is no time to turn back. We will hold to our course and we will complete this mission."

Budget details

Meanwhile the Treasury confirmed, in a written statement to Parliament, that Chancellor Alistair Darling will deliver his much-awaited pre-election Budget on Wednesday 24 March.

The Conservatives have pressed the chancellor to use the occasion to give more detail about how he intends to meet Labour`s commitment to cut the deficit in half over the next Parliament.

They say the financial markets need greater reassurance on the matter, likening the deficit to a "dark cloud" hanging over the economy and its future recovery prospects.

On Sunday, Mr Darling said he was "absolutely committed" to this goal and said his tax and spending statement would show he was "on course" to cut borrowing from its forecast peak of £178bn this year.

He has ruled out a full spending review until there is more certainty about the economy and while promising to protect spending on health and schools has warned of "difficult choices" elsewhere.

Economists have warned that substantial spending cuts and further tax rises will be needed in the medium term to tackle the deficit but opinion is divided on when this process should begin.
