Supermarket Morrisons posted a sharp fall in like-for-like sales over Christmas, blaming the "disappointing" performance on difficult market conditions, heavy discounting by rivals and the lack of a full online offer.
The UK's fourth largest supermarket chain said its like-for-like sales excluding fuel dropped 5.6% in the six weeks to January 5th.
Including fuel, the drop was 7.1%.
It said it now expected its full-year underlying profit performance to be towards the bottom of the range of current market expectations, which stand at £783m to £853m.
