Former Sainsbury’s chief executive Justin King is to join the board of Marks & Spencer as a non-executive director in the new year.

King, who won plaudits for reviving Sainsbury’s fortunes over a 10-year tenure, previously worked for M&S when as food boss he played a key role in the launch of Simply Food.

He was also part of the turnaround team at Asda, which was rescued from disaster by Archie Norman, who is now chair of M&S.

M&S said King “brings in-depth experience of retail transformation and operations as well as a good historic understanding of the M&S business and values”. His appointment “is a further step in the creation of a very strong transformation board for M&S”.

Norman added: “Justin’s appointment completes a very significant reorientation of the board in the last year. He will be a great addition to a strong team.”

M&S chief executive Steve Rowe said: “I am delighted that Justin has agreed to join us. As we navigate the challenges ahead it will be enormously helpful to have his experience, wisdom and insight on the board. Many colleagues remember his time at M&S and will warmly welcome him back.”

King said: “Having worked there 15 years ago, M&S has a very special place in my affections. I look forward to joining the board and supporting Steve in the turnaround that he is leading.”
