While the grocer's like-for-like sales softened 1.1% (excluding fuel) over the 12 weeks to 7 June, a second consecutive quarter of falling sales amid discount competition, Sainsbury's shows it is performing better than embattled rivals Morrisons (MRW) and Tesco (TSCO) in a weak grocery market.

Analysts conclude from the results commentary that the group is 'slowly turning a corner' from earlier problems.
