GORDON Brown hailed today’s economic growth figures as a "hugely optimistic moment" but warned Britain was not "out of the woods yet".
The Prime Minister, campaigning in Coventry, said the 0.2% rise in GDP confirmed the recovery was "under way".
He added: "This is important and it’s a hugely optimistic moment for all of us."
Mr Brown said the figure defied "predictions of doom and gloom" and warned the Tories would put the recovery at risk by taking £6 billion out of the economy.
Mr Brown acknowledged that his job was ``on the line'' in the election.
"Mr Cameron and Mr Clegg would like to have my job. That’s fair enough. But it’s your job I care about and their policies would put your jobs at risk."
He pledged: "I will fight with all the energy and passion I can muster to win support for a majority Labour Government that can take the economy and the country forward.
"I know I’ll never beat Mr Cameron or Mr Clegg on style. But I believe I beat them on substance and policy and it is substance and policy that is needed to lead Britain into the future."
The GDP figure of 0.2% was equivalent to around £600 million of growth.
"For the Conservatives to cut £6 billion from the economy now would risk reversing our progress and creating a double-dip recession."
Mr Brown admitted that he too had "worried" when the financial crisis broke.
"These were scary times. I’ll be honest, times when I too worried about what we would have to do to stabilise things and get the situation under control.
"But we did get the situation under control and we made the right calls..."
Today’s figures were "defying the predictions of doom and gloom from those who would always talk Britain down".
Mr Brown warned: "The recovery is fragile. We aren’t out of the woods yet and we must do nothing to put the recovery at risk."
Mr Brown went on: "This country has known recessions before, what I am seeking to secure, and what I believe is achievable, is that we avoid a Tory double dip recession that would result from their policies and instead have a post-recession triple boost,
"I mean triple boost by growth, by rising employment and by keeping interest rates low.
"None of this will happen by chance, it will happen by choices we have made and will make and the choices we are making now for the future.
"Learning the lessons from past Tory recessions, where interest rates were so high that homeowners could not afford mortgages and businesses could not afford to invest.
"Learning the lessons from past recessions when unemployment continued to rise, even after the official end of the recession, for two three or four years after the recession was technically over.
"That was the Tory way - this is the Labour way and the calls being made by Mr Cameron and Mr Osborne now mean that they have learnt nothing from their own party’s past.
"They may have changed the wrapping, but scratch beneath the surface and it is the same old Tory party.
"Our economy is too important, our hard-earned recovery is to fragile to let these novices play with it now."
Mr Brown said: ``People talk of this being a fight for a fourth Labour term, indeed it is. But it is the first post-economic crisis election also.
"Never were experience and judgment more called for than now. For this is a moment of big risk and big choices.
"Get the choices right and we prosper, get them wrong and let the bad times return with a vengeance.
"Ask me my three priorities here and now, April 2010 and I tell you: Jobs. Jobs. Jobs."
Mr Brown said: ``Be clear that, if the Tories had been in charge when the crisis hit, very many more jobs would have been lost as they stood aside and left events to take their course.
"Of all the big calls, Northern Rock, re-capitalising the banks, help for small businesses, support for homeowners, most importantly the fiscal stimulus backed by every major government in the world, the Conservatives argued for a more different and dangerous course.
"If we had listened to them, we estimate that as many as 1.7 million more jobs would have been lost. That is the scale of risk, that is the scale of danger these people present to the economy.
"Wrong decisions because of wrong values leading to wrong calls."
Mr Brown added: ``I believe they have still learned nothing. So they call to take billions out of the economy now when it needs it most.
"It is the wrong decision, they have the wrong values, it leads them again to the wrong calls.
"I just say there would be more jobs lost from reversing the modern industrial policies we know can help lead us from recession to a more greener, fairer, more prosperous future."
Mr Brown said the Tories would make a number of tax cuts - ``inheritance tax cuts for the wealthiest families in Britain, a tax cut for one in three of married couples, they want to abandon the plan for a necessary rise in National Insurance''.
But he warned: "The money has to come from somewhere to pay for our hospitals, schools and police...
"Their sums simply do not add up. It is why they have stumbled in this campaign.
"Their economic lack of credibility (and) Mr Clegg’s TV and PR skills have put paid to any idea that this is an inevitable Tory procession to Downing Street."
The Conservatives would cut jobs programmes, school leavers’ programmes, regional policy and industrial policies, he warned.
"Only one party wants to talk policy and not about prose or presentation," he said.
"Only one party has a credible, costed, coherent plan for the future.
"And I believe only one leader understands the challenges that we face and how to meet them in the future.
"That is not David Cameron, nor is it Nick Clegg. We have shown we can manage the economy in good and bad times.
"The recovery is under way but it is still fragile. We must not let the Tories wreck it."
