Marks & Spencer’s group financial officer, Humphrey Singer, is set to leave the business after 14 months in the role.

M&S said in a statement that Singer had decided to step down, and is working with M&S chief executive Steve Rowe to find a replacement.

This comes after Jill McDonald, who headed up M&S clothing was ousted in July.

A leaving date for Singer has yet to be decided.

Rowe said: “Humphrey has been a huge asset to the business. He has helped to establish the foundations of our transformation with a stronger balance sheet, robust financial controls and a much keener focus on reducing our cost base. In addition, he was a critical part of the team which guided Marks & Spencer through the deal to create our joint venture with Ocado and subsequent equity raise.”
