Sainsbury has posted a 0.3% rise in first quarter like-for-like sales and blamed its transformation programme both in-store and within the supply chain for “disruption to the execution of our customer offer”.

UK like-for-like sales including petrol and adjusted for Easter grew by 0.3%. Total UK sales grew by 2%.

Group chief executive Sir Peter Davis said : “I am not satisfied by our sales performance during the last two quarters.

He added that the next 12 months were "most important in the delivery of our change programme, when the first two years of groundwork and capital investment really take hold".

"It is the board’s top priority to ensure that this programme is fully completed. We will then have a leaner, fitter business in better shape to compete in the UK’s dynamic food retailing sector."

Davis reiterated that the group's recovery programme remained on track and that Sainsbury would deliver its cost savings target of £250m.

Sainsbury said its supermarket business In the US , Shaw's, had like-for-like sales growth of 0.8% while total sales were up 1.1%.
