Retailer Marks & Spencer has overhauled its top team after reporting its worst performance in non-food sales for more than three years.
Kate Bostock, who is responsible for clothing ranges as head of general merchandise, will leave the group in October, with former Debenhams and Jaeger boss Belinda Earl coming in as style director.
The 6.8% decline in clothing and general merchandise sales in the 13 weeks to June 30 - the worst since December 2008 - will ramp up pressure on chief executive Marc Bolland, who faces shareholders at the company's annual meeting on Tuesday. He has blamed continuing stock supply issues and the poor weather conditions for the weak trading figures at the company's 700 stores in the UK.
The retailer is now worth less than rival Next on the London stock market, while online fashion store Asos added to the strain on M&S by reporting a better-than-expected 8% rise in UK sales today.
The figures will fuel fears that Marks, the UK's biggest fashion retailer, is losing its grip on the key womenswear market, with some analysts reporting that its ranges are off-trend.
Independent retail analyst Nick Bubb said: "M&S's problems in womenswear go far beyond the weather as they are clearly losing market share."
He added that Ms Bostock, who has been linked with a top job at Asos, had been made a scapegoat as Mr Bolland fought for his job.
Her role will be taken by John Dixon, who has been with the company for 26 years and is seen as a potential successor to Mr Bolland.
Ms Earl, who will work for the chain for two to three days a week, left Jaeger earlier this year after a period of sick leave. She was chief executive of Debenhams between 2000 and 2003 and is credited with rolling out its successful Designers At Debenhams range.
The appointments were welcomed in the City, with shares up 2% despite the disappointing sales figures.
