Royal Mail's parent company International Distributions Services reported a first-half loss of 57 million pounds ($67.88 million) as higher costs and disruptions arising from strikes by its postal workers put a strain on its finances.

The former British postal monopoly, which recently changed the name of its holding company from Royal Mail Plc, still expects full-year adjusted operating loss for the UK business of around 350 million to 450 million pounds.
