The boss of Britain’s air traffic control service is facing calls to resign over what critics said was the latest in a string of failures under his watch.

Ryanair has called for Nats' chief executive Martin Rolfe to resign after the air traffic control fault on Wednesday. The airline claimed "no lessons have been learnt" since the August 2020 system outage.

Britain’s transport chief has summoned the head of the country’s air traffic control operator to explain the problem that grounded and diverted dozens of flights.
