UK supermarket group Asda has revealed that it is closing two on-line shopping depots in Watford and Croydon.

The closures will mean that consumers in and around London can expect only a “skeleton service” for the next two months, and the retailer switches to a process whereby groceries purchased online through will now be hand picked from the store shelves.

Asda explained: “We are expanding. This [process] will give our rivals a run for their money.”
