Trouble with a computer upgrade has been causing chaos at some of the chain’s branches
Waitrose has insisted its supermarkets are better-stocked than some of its rivals despite claims that a bungled IT project has left many of its stores with empty shelves.
The supermarket, which is owned by the John Lewis Partnership, said independent data showed product availability at its branches was higher than at competitors.
In a post on Twitter, Waitrose said: “We’re not complacent and as always we’re working hard to give our customers the best Christmas.”
However, a spokesman did not deny a report that trouble with a multi-million pound computer upgrade has been causing chaos at some of the chain’s branches.
