Hopes of a sustained recovery have been fuelled after official figures revealed Britain's economy grew by a better-than-expected 0.8% during the third quarter.
The quarter-on-quarter rise in gross domestic product (GDP) was less than the 1.2% surge in the previous three months, but double the growth expected by most experts.
Economic growth over the past six months has now hit 2%, which is the fastest pace of expansion seen over two consecutive quarters for 10 years, according to the Office for National Statistics (ONS).
The ONS said, allowing for a bounce back in the second quarter following the bad weather at the start of the year, the underlying growth between July and September was actually similar to that of the second quarter. Year-on-year growth has recovered to levels seen before the recession, reaching 2.8% in the third quarter - the highest annual rate of expansion since 2007.
While the figures are only a preliminary estimate and may be subject to change, the initial growth figures are likely to give a boost to Government deficit-busting plans.
On Monday Labour leader Ed Miliband accused the Government of taking a "big gamble with growth" by pushing through deep public spending cuts, but a stronger recovery in the private sector should give Britain a better chance of withstanding austerity measures.
The ONS data revealed a surge in construction output helped drive growth in GDP, growing by 4% during the third quarter and contributing 0.2% of the overall 0.8% expansion. Output in the key services sector - accounting for three quarters of the economy - was 0.6%, while industrial production also grew by 0.6%.
GDP has now grown for four consecutive quarters, but there are fears this will not be sustained as the Government cuts take effect.
Prime Minister David Cameron promised a "relentless focus on growth" on Monday to help fill the hole left by the coalition's austerity measures, expected to cost 490,000 public sector jobs.
Chancellor George Osborne told the Cabinet this morning that "some confidence" could be taken from the latest growth figures. "He said the global situation remains relatively choppy but the figure... is something we can take some confidence from," the Prime Minister's spokesman said.
