"In order to strengthen the recovery it is important that we boost consumer confidence and demand and that interest rates are held steady as continued investment in the economy will be the key to ensuring a sustainable recovery," he said.
Meanwhile, Lee Hopley, chief economist at manufacturers organisation EEF, said: "Whilst today's data confirm that manufacturing is now out of recession, they also continue to raise questions over the health of the wider economy.
"The trajectory for the recovery, particularly in the next six months, is an uncertain one and the best prospects remain an export-driven turnaround."
First estimates of how the economy has performed are made with about 40% of the data available, and Investec economist David Page has warned there is "plenty of room for surprises" in the figures.
But the BBC's Economics Editor Stephanie Flanders said: "Even with some revision - in fact, even if it turns out that the economy actually started to grow in the third quarter, given that the first estimate of a decline 0.4% has already been revised up to -0.2% - we are still talking about an extremely lacklustre recovery."
Chancellor of the Exchequer Alistair Darling said he was now sure that "we are on a path to recovery.
"I'm confident but I'll always remain cautious".
But shadow chancellor George Osborne told the BBC that the UK needed a "new model of economic growth" under a Conservative Government.
He added: "Let's be clear - this is about as weak growth as you can get."
Liberal Democrat Treasury spokesman, Vince Cable said the markets would be surprised that growth had been markedly slower than expected.
"Far from the quick recovery the chancellor has been praying for, the economy is only just staggering back into growth," he said.
