UK department store John Lewis has reported a slight sales decline over the past week amid warmer weather.

"Our trade levels were just a whisker short of last year at -0.8 per cent which was a credible result given we had a very good week of weather against us last year and this year there was rain and even hail in parts of the UK," said Lesley Ballantyne, director operational development at the chain.

John Lewis was reporting on its 17th week to 28 May 2010-11, which last year saw sales soar 23.6%.
