The Bristol branch of John Lewis was one of five stores which saw sales fall by more than 20 per cent last week

The group's weekly trading update revealed a 23 per cent drop at Nottingham, while outlets at Peterborough, Reading, Bristol's Cribbs Causeway and Peter Jones in London were also down by more than a fifth on a year earlier.

John Lewis disclosed on Sunday that sales across the division were down by more than 13 per cent in the week to last Saturday. The period saw rivals Marks and Spencer and Debenhams hold discount days in a bid to drive footfall in the run-up to Christmas.

Despite the increased competition, John Lewis merchandise director Jill Little said the chain held its own during the week, particularly in fashion, after matching the price cuts on branded lines.

She said: "A week of high profile competitor reductions give an indication that most retailers are finding themselves in tough times. Throughout this, we can remain confident in the honest pricing strategy we have always delivered for our customers."

The group's fashion department provided the best performance in the week, with sales down by 7.7 per cent on a year earlier. Electricals and home technology dropped 13.2 per cent and Home revenues slumped by 19.6 per cent.

One of the week's best sellers was Biscuit the Dog, a life-size electronic toy retriever puppy.

At supermarket chain Waitrose, which is also part of the John Lewis Partnership, sales were down 3.9 per cent.
