Rivals 'reduce Tesco market share' in the UK

Rival supermarkets took a further slice out of Tesco’s market dominance in the UK during the key Christmas battleground period, figures suggested today.

Ahead of the retailer’s festive update on Thursday, research firm Kantar Worldpanel said the chain’s share of the market for the 12 weeks ending on Christmas Day dropped from 30.5% a year ago to 30.1%.
