Waitrose has been criticised by the the Competition and Markets Authority (CMA) over seven breaches of an order put in place to stop large grocery retailers gaining an unfair advantage.
The chain, which is part of the larger John Lewis group, breached one of the two orders put in place following the Groceries Market Investigation.
The watchdog said the breaches took place in Bromsgrove, Rustington, Swindon, Daventry, Chester, Notting Hill Gate and Market Harborough.
