Details have emerged of the location of some of the 126 stores The Co-operative Group has to sell in order to complete its £1.57bn acquisition of Somerfield.

Seventeen are in Scotland, including one in Wick, which has a Co-op store and a Somerfield within a third of a mile of each other.

It is also understood that stores in Wellington in Somerset and Steyning in West Sussex are on the list. Wellington has a Somerfield and a Co-op store less than half a mile apart, while the stores in Steyning are less than 100ft from each other.

Staff involved had been briefed, a Co-op Group spokeswoman said, but she would not reveal which Somerfields or Co-op stores would be sold.

Last week the Office of Fair Trading cleared the deal but ruled that there were competition concerns in 126 local markets.
