Jo Whitfield said: "I always knew that this year would be a big year with my boys undertaking key exams. We decided as a family, that in order to prepare for the inevitable pressure and emotional turmoil that would involve, that when the time came, I would look to spend more time with them to ease the challenge.
"I can take this time away reassured by the knowledge we have a strong food leadership team who will keep moving our Co-op forward, working with support and guidance from Steve Murrells, our Co-op CEO."
Mr Murrells added: "We will miss Jo and wish her and her family well over the coming months."
Jo Whitfield has been CEO of Co-op Food since March 2017, having first joined the Manchester-headquartered group as the division's chief financial officer in April 2016.
