Marc Bolland begins his tenure as chief executive of Marks & Spencer today.
The former Morrisons boss will take over the reins from outgoing executive chairman Sir Stuart Rose following a handover period.
Sir Stuart is switching to become chairman in July.
The surprise appointment of Bolland caused controversy earlier this year when it emerged that he was in line to pocket up to £15m in his first year at the high street icon in salary and shares, bonuses and compensation for lost earnings at Morrisons.
His successor at the Bradford-based supermarket, former Loblaw executive Dalton Philips, began at Morrisons in March.
