Rose Foster, CEO of UK lingerie retailer La Senza, left her post today (13 February), having "completed her assignment", according to the company.

La Senza said that, with immediate effect, the business would be run on a day-to-day basis by former managing director Malcolm Cooke, and former owner and current director Theo Paphitis.

The company gave no other reason for Foster's departure, but said of Cooke and Paphitis: "As the company continues to trade in a difficult economic climate, their significant experience in the retail sector ensures the company is well-placed to address the next phase of its successful growth."

Foster, who joined La Senza from fashion retailer Monsoon in April 2007, was responsible for a strategic review of the business, which led to its rebranding and the introduction of a new store concept.

She also oversaw an expansion programme which led to the opening of 35 new stores, including La Senza's biggest outlet in the new Westfield shopping centre in west London.
