The revised GDP data showed a quarter-on-quarter fall of 0.5 per cent for the three months to September, compared with last month's preliminary estimate of a 0.1 per cent decline.
The economy contracted at an annualised rate of 1.8 per cent between July and September – a much more precipitous pace than the annualised 0.5 per cent decline suffered in the same quarter by the US, centre of the global financial crisis.
Analysts said the revision, though bigger than expected, reflected relatively technical factors involving inventories and government spending rather than worrying new information and so would not dramatically change assessments of the economy's prospects.
