Earlier today M&S posted an 8.8% rise in group like-for-like sales over the first half of the year and that strong food sales were boosted by the opening of three new Simply Food stores.
Food like-for-likes increased by 6% in the second quarter, and were up 3.6% over the first half.
Interim clothing and home like-for-like sales rose 13%.
Chief executive Roger Holmes said food sales were driven by product innovation and quality and that M&S was on track to open 20 Simply Food stores this year.
Interim pre-tax profit to September rose to £285.3m from £213.3m last year on turnover that increased 7.9% to £3.7bn.
Chairman Luc Vandevelde said: “Looking forward, we are now focused on gaining market share in the core areas, particularly clothing and food, and on building the foundations for future growth.
