The Co-op Group announced it is planning to cut around 400 jobs at its head office in Manchester.
A spokesman for the Co-op said: “At our last set of annual results, we shared that as part of our strategy, making our Co-op more efficient and cost-effective was a priority.
“The tough trading environment, including rising inflation, means we have taken the difficult decision to bring forward some of the changes we had planned for 2023.
“These changes, designed to simplify our approach to business, will sadly mean a number of colleagues in central functions will leave the business.
“We make these changes with a heavy heart, but it is the right thing to do for the long-term health of our Co-op and for all of our members.”
The mutually-owned Co-op employs more than 60,000 people and makes revenue of more than £11 billion.
