People in the UK are drinking more, and stronger alcohol, government figures suggest.

The Office for National Statistics yesterday reclassified its method for assessing safe levels of alcohol for the first time since 1978 and found alcohol consumption had increased from 10.8 units a week to 14.3 units.

Most wines were also found to be in the 11.5% to 13.5% alcohol by volume range, compared to 9% when ONS first carried out its drinking surveys.
