The Co-op is planning to invest more than £240m into its membership proposition so it can cut prices for customers.
The Manchester-based group, which runs more than 2,400 food stores, announced the five-year investment plan as part of its broader turnaround efforts.
The investment will support lower prices that will only be available to the Co-op's 4.5m members. The group also hopes to grow its membership by a further million over the next five years.
