Food retailer Waitrose has announced it's to part company with Delia Smith at the end of February by mutual agreement but is extending Heston Blumethal's contract when it expires at the same time.

The celebrity chef duo were contracted in 2010 as part of a new marketing strategy intended to encourage consumers to cook from scratch, by sharing expertise and recipes. Rupert Thomas, Waitrose Marketing Director said 'It has been such a fantastic experience working together and we have been really appreciative of the work Delia has done with Waitrose'.
