Asda's £600m deal to buy the Co-op's petrol station business could result in higher prices or less choice in 13 locations, the Competition and Markets Authority (CMA) was warned.
The judgement comes after an official inquiry was launched into the deal in January after the transaction was completed towards the end of last year and saw 2,300 workers move over to the supermarket giant.
In August 2022, the Co-op first revealed plans to sell its 132 petrol stations and attached convenience stores in a bid to bolster its finances.
