SUPERMARKET giant Sainsbury appears to be slowly clawing back some of its market share, according to a survey published today.

Research group AGB's July figures show the firm won 21.1 per cent of the market, up from June's 20.6 per cent, and 20.1 per cent in May,

Rivals Asda and Tesco saw small slips in their share, while market leader Safeway increased both its sales and growth.
