The Royal Mail is launching trials of parcel deliveries and office openings on Sundays, it has emerged.
The parcel deliveries will all be made within the M25 area and customers will be able to collect them from around 100 offices at the end of the week.
Royal Mail said the move was aimed at making it easier for online shoppers to collect their purchases if they were not at home on a weekday.
Offices will be open for four hours from noon on a Sunday.
Nick Landon, managing director of Royal Mail Parcels, said: "We are continuing to be more customer-responsive and provide more options for people to receive items they have ordered online."
