Tesco’s market share increased to 29% in the 12 weeks to 2 January, compared to 28.7% a month earlier and 26.6% in the year-ago period, reported Reuters.


Supermarket group Wm Morrison continued to leak market share after its takeover of rival chain Safeway. The combined market share of Morrisons and Safeway was 12.4% in the 12-week period, compared to 12.8% a month earlier and 14.5% in the year-ago period.

“Sainsbury, while not setting any records, has slowed its rate of decline…Christmas is traditionally a strong period for the outlet and the share duly rose for the fourth period in succession,” Edward Garner, communications director of TNS Superpanel, was quoted by Reuters as saying.
