British postal operator Royal Mail Group is abusing its dominant market position, according to several of its major customers.

Consumer watchdog Postwatch has submitted a complaint to the Office of Fair Trading after a number of businesses expressed dissatisfaction about their dealings with Royal Mail.

The businesses in question include “major household names”, says Postwatch, though their identities were not disclosed for fear of affecting their relations with the near-monopolistic operator.

The complaint centres on the contracts the businesses have signed with Royal Mail. They claim these permit the postal giant to alter its mail delivery terms at will and with scant notice.

Blasted Postwatch: “It is between consenting adults, but one of the adults can say ‘like it or lump it’ and the other has no other choice.”

The OFT will adjudicate on the complaint within 90 days.
