Royal Mail faces possible fine as regulator looks into late deliveries

Only 73.7% of first-class mail and 90.7% of second class met delivery targets, according to the postal service

The communications regulator has launched an investigation into poor performance at Royal Mail that could lead to a fine after more than a quarter of first-class mail was not delivered on time.

Ofcom said it would examine the postal service operator’s failure to meet targets during a year marked by a long-running industrial dispute, which led to the resignation of the chief executive on Friday.
