Former Greencore director, Eoin Tonge, will be joining the board of Marks and Spencer as chief financial officer in June.

Tonge replaces Humphrey Singer, who left M&S last September after the company was demoted from the FTSE 100.

Formerly the chief strategy officer and managing director of Greencore’s grocery division, the UK’s biggest sandwich supplier, Tonge oversaw the sell-off of the company’s US division and simplified the business.

Marks and Spencer says David Surdeau, currently interim CFO, will remain with the business to support Eoin as he transitions into his new role.

Tonge said of his appointment: “Marks & Spencer is a brand that I have admired as a customer as well as a supplier for some time. I’m excited to be joining the Board and management team to drive forward the transformation of the business, realise its full potential and make it special again.”

Group chief executive, Steve Rowe, said: “Eoin’s appointment concludes a rigorous search for a world-class finance director. He brings in-depth knowledge of food, as well as strategy and operations, and is another addition to the very strong management team we are building to transform M&S.”
