Officially the statistics say the UK economy has returned to growth, but remember these figures are only an estimate...

You could feel the uneasiness among economists yesterday when the release of official statistics showed that the UK had just scraped enough oomph together in the final quarter of last year to stage a lacklustre return to growth.

Most economists had expected the no-growth bar to be cleared by some margin. Instead the preliminary estimate figure posted at 0.1% growth leaves open the possibility that further revisions could show the UK still in recession. Unlikely, but not an outlandish possibility.
