Bonjour project manager Iain Cracknell said a total of 10 Bonjour sites would be open by the end of this year, mainly in south east England. The roll-out would also focus on that region.
Cracknell said the stores were not intended to directly compete with c-store formats such as Tesco Express and Sainsbury's Local. "We would not be able to replicate the kind of offer Sainsbury's Local does. We're just introducing a destination for top-up shopping.
"But Bonjour sites are very different to our normal forecourt shops. They will have more of an emphasis on convenience and fresh food."
