Royal Mail’s Saturday letter service should stay, says Downing Street

Regulator due to lay out options for future as operator claims six-day service is unsustainable

Downing Street has indicated that the government will oppose Royal Mail plans to scrap Saturday letter deliveries, as the regulator assesses the possibility of cuts to the postal service.

Ofcom, the communications industry regulator, is expected to publish a series of options for the future of the postal service when the results of a five-month-long review are published this week, probably on Wednesday.
