In a statement on Friday, Gleeson said it was “a good time for me to take on a fresh challenge” after eight years with the retailer. 

The announcement comes ahead of a period of refinancing for Morrisons some six months after CD&R beat off strong competition to acquire the business.

Morrisons chief executive David Potts said of Gleeson: “Michael has made a significant contribution to the business over the last eight years. He leaves us with our sincere thanks and with our best wishes for his future endeavours.”
