Britain remains stuck in a record recession, official data showed yesterday, but economists forecast a return to growth before the end of the year and ahead of a general election.

The economy shrank by 0.3 per cent in the third quarter, compared with output in the previous three months, the Office for National Statistics said in a statement.

This was an improvement on an initial ONS estimate given last month that said the economy had contracted by 0.4 per cent between July and September.

"The third-quarter GDP data for the United Kingdom showed a minor upward revision, in line with expectations," said economist Charles Davis at the Centre for Economics and Business Research consultancy.

"This is still some way short of the return to positive growth seen in the eurozone and OECD as a whole," he added.

The eurozone, France, Germany, Japan and the United States have all returned to growth following the worst global economic downturn since the 1930s.

Britain, suffering from high unemployment and massive public debt caused by the financial crisis, is to hold a general election by mid-2010, which Prime Minister Gordon Brown's Labour government is widely expected to lose to the main opposition Conservatives.

Analysts say the main reason for this is the state of the British economy - which has contracted for six quarters in a row, Britain's longest recession since records began in 1955.

"GDP contracted by 0.3 per cent in the third quarter of 2009," the ONS said yesterday.

"This has been revised from a fall of 0.4 per cent in the preliminary estimate of GDP, due to upward revisions to services. GDP is 5.1 per cent lower than the third quarter of 2008," it added.

The quarter-on-quarter and annual figures for the July-September period were both in line with analysts' consensus forecasts.
