The estimate of economic growth between April and June was revised upwards yesterday, following better-than-expected output in the manufacturing sector.
It is now thought the UK economy grew by 0.5% in the quarter and by 1.8% on the same period a year earlier - the lowest rate since the start of 2002.
The new figures from the Office for National Statistics compare with a previous forecast of quarter-on-quarter growth of 0.4% and 1.7% for the full year, a return which had been the worst rate for 12 years.
The revision came after output in the beleaguered manufacturing sector was shown to have fallen by 0.3%, compared with a previous forecast of 0.7%. A sharp rise in exports lay behind the revision for the industrial sector.
