Regulator sets out possible ways forward in review of requirement to deliver across Britain, six days a week

Royal Mail could save up to £650m if it delivered letters just three days a week and £200m by stopping Saturday deliveries, the communications regulator has said.

The watchdog said a reduction from six to five days a week would save £100m to £200m, and going down to three days £400m to £650m.
