Tesco’s share of Britain’s £140 billion a year grocery market fell to 28.8 per cent in the 12 weeks to 14 September compared with 30.2 per cent a year previously.
Meanwhile the combined market share of Aldi and Lidl, which have both aggressively targetted middle class shoppers, rose from 6.7 per cent to 8.3 per cent.

He was previously in the same post at Marks and Spencer. His arrival fills a gap left by Laurie McIlwee, who left just over a week ago, following his resignation in April.
