Marks & Spencer has revealed ambitious expansion of its food business, with plans to focus on healthy eating, labelling and expanding its Simply Food network.

CEO Stuart Rose announced plans to open 100 Simply Foods this year, of which 60 would be situated on BP forecourts.

The details emerged as M&S reported a 4.2% rise in full-year like-for-like food sales. UK food sales rose 9.7% to £3.9bn for the year to 31 March.

M&S said it would triple its 400-strong range of organic products in the next three years, increase specialities from 300 to 400 by the end of the year and extend its 70-strong Fairtrade range. Fifty per cent of its food would be labelled with its sunflower logo Eat Well.

It added that it would extend its combination of traffic lights and GDA front-of-pack nutritional labelling across all recommended FSA categories and extend recycling labelling to the "vast majority" of its food lines by the end of the year.
