British retailer Marks & Spencer has announced a management reshuffle.
It said chief executive Stuart Rose would move to chairman and stay with the firm until 2011, and that finance chief Ian Dyson would get a bigger role.
Ian Dyson, finance director, will also become head of operations, taking on the responsibility for the retail business.
The management overhaul also sees a number of senior positions axed under plans to 'streamline' the business.
The company said chairman Terry Burns would stand down on June 1, with Rose becoming executive chairman from that date.
Burns, who will leave M&S after more than two-and-a-half years, said Rose's new position would allow him to focus on finding a successor.
Rose has been widely credited with reviving the chain since returning to the group as chief executive more than three years ago.
The retail stalwart started his career at M&S in 1972, but quit in 1989 to join the Burton Group.
He has acted in a number of senior retail roles - as chief executive of Argos, Arcadia Group and Booker - before re-joining Marks & Spencer.
Marks & Spencer saw a return to strength in 2006 with surging sales figures and profits, although its figures have since come off the boil amid a downturn in consumer spending.
M&S reported its worst quarterly trading for more than two years in January with a 2.2% drop in Christmas sales.
Rose said market conditions became tougher in November and December and warned of difficult trading to come in 2008.
