The British economy grew slightly more strongly in the third quarter of 2011 than previously believed, but was flat in the second quarter, the Office for National Statistics said.
Growth in the three months to September was 0.6 per cent, up from an initial estimate of 0.5 per cent. But growth in the three months to June was revised down by the statistics body from 0.1 per cent to zero.
The change in the third quarter estimate was driven by a revision to businesses investment, which grew by 0.3 per cent over the quarter, after a previous estimate of a 1.4 per cent contraction.
The statistics office also said that the economy grew more strongly last year than previously thought. Output growth was 2.1 per cent in 2010, up from an estimate of 1.8 per cent.
The revisions do little to change the overall picture of a weak economy, and analysts warned that Britain is still in danger of undergoing a contraction in the coming months.
