Greggs will initially open shop-in-shops in five Asda stores as part of the pilot, with the first due to launch next month.

Asda said its supermarkets in Boldon, Corby, Huyton, Eastlands and Wigan will host the first Greggs concessions.

The locations will stock Greggs’ full range, including its popular vegan sausage rolls, steak bakes, breakfast rolls, sandwiches, wraps and hot and cold drinks.
