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.

A radar problem used within the UK's air traffic control system caused chaos at airports in the UK and beyond on Wednesday. The fault lasted a mere 20 minutes, but was enough to ground planes across the country, causing 150 flight cancellations and delays that have continued into Thursday.
