Rose’s change of responsibility becomes effective from June 1 and is part of a raft of management changes at the high street giant.

Marks & Spencer’s incumbent chairman Lord Burns will stand down and Sir David Michels will become deputy chairman.

M&S finance director Ian Dyson will become group finance and operations director, adding retail and human resources to his existing responsibilities.

Womenswear supremo Kate Bostock and Steve Esom will be promoted to the M&S board. Bostock will take responsibility for all clothing, including menswear, other than Per Una. Steven Sharp will retain his existing role as M&S executive director, marketing.

M&S retail director Guy Farrant is among a number of senior executives that will leave M&S. Others include human resources director Keith Cameron, who will retire in April.

The retailer said that changes “will ensure continuity of leadership, strengthen the board and streamline the organisation to maximise its growth potential”.

Lord Burns said: “Since Stuart returned to M&S, the company has made substantial progress. It is my view and the unanimous view of the independent directors that placing Stuart in this new role creates the right leadership structure for the company.”

Rose said: “M&S is a business with a strong heritage and great potential. This is an important time in its development. In taking on the role of executive chairman my task will be to guide the business through the next stage of growth.”
