There is a long slog ahead for UK businesses after economic growth slowed in the final quarter of 2010, a research body has warned. UK GDP grew by 0.5% in the final quarter of last year, down from a rate of 0.6% in the previous three months to November, according to the National Institute of Economic and Social Research. For the full 2010 calendar year UK growth is forecast to have been 1.6%. Despite this the institute ruled out a return to recession for the economy in 2011, but said that output was unlikely to surpass its 2008 peak until 2012 at the earliest. The news came as the Bank of England decided to leave UK interest rates on hold at 0.5%
