Sainsbury’s market share has recently increased faster than Asda’s for the first time in a decade, according to the latest UK food market share data by TNS.

Sainsbury’s market share grew 4.1% during the 12 weeks to 27 March, while Asda’s slowed to 3%. This growth led to Sainsbury increasing its share of the market to 15.9% against 15.7% last year, while Asda’s share was flat at 16.6%.

Tesco once again delivered a good performance for this period, reaching a market share of 29.5%.

The data also showed that Waitrose is continuing to benefit from store acquisitions from Morrison. Its sales growth of 17.5% was aided by its acquisition of 19 former Safeway stores from Morrisons.
