After the biggest slump since 1949... the recession is officially over

A 0.1% expansion in the economy between October and December ended six straight quarters of shrinking output, according to first estimates from the Office for National Statistics.

Overall, the economy slumped 4.8% last year - the biggest annual contraction since records began in 1949 - and it has lost 6% since the recession began in 2008.

A Treasury spokesman said: "The Chancellor has always said that the economy would return to growth by the turn of the year, and today's estimate of 0.1% growth in the fourth quarter bears that judgment out.

"What this estimate makes clear is that the Government is right to be confident but cautious about the prospects for the economy and that it is right that we keep supporting the economy.

"Withdrawing the support that has helped us get to this point would put the recovery at risk."

The expansion in the UK economy is weaker than the 0.4% predicted by economists.

Lower-than-expected growth will fuel fears that the recovery could be weak and worries over a so-called "double dip" recession.

Public borrowing has ballooned to an estimated 178 billion in the recession, which began in the second quarter of 2008.

The UK is the last of the G7 nations to pull out of decline and an end to the slump is likely to ease political pressure on Prime Minister Gordon Brown ahead of this year's general election.

Survey data has pointed to an upturn for both manufacturing, while the first fall in unemployment for 18 months has also suggested a return to growth.

The fourth-quarter upturn was driven by the distribution, hotels and restaurants sectors, according to the Office for National Statistics.

Government and other services also helped the expansion, although there was a small decrease in business services and finance in the quarter.

The beleaguered manufacturing sector increased by 0.4%, having been mired in decline since the first quarter of 2008.

Today's estimate is based on just 40% of the relevant data, leaving the measure vulnerable to revisions in either direction when the ONS publish their next estimate in February.

The third quarter of 2009 also came in weaker than economists had predicted, with hopes of a return to growth dashed by the ONS first estimate showing a 0.4% decline, later revised upwards to a 0.2% fall.

Jonathan Loynes, an analyst at Capital Economics, said the figures were "a major blow" to hopes that the UK economy had emerged decisively from recession.

He added: "With household incomes under pressure, credit in short supply and a major fiscal squeeze looming, the path to a full recovery is going to be a long and bumpy one.

"We still expect average GDP growth of a below-consensus 1% or so in 2010."

Hetal Mehta, senior economic adviser to the Ernst & Young Item Club, said the preliminary GDP estimate was at odds with much more upbeat survey data.

"There is a strong possibility that the Q4 figures will be revised up," she added.
