Tesco market share slips again

The dominance of market leader Tesco has continued to wane as competition between low-cost supermarket rivals rages on, industry figures have shown.

Tesco's market share has slipped from 30.3% this time last year to 29.7% in the 12 weeks to February 19, a further decline on the 29.9% reported by Kantar Worldpanel last month.
