There are warnings of further disruption after an issue with air traffic control saw hundreds of flights across the UK on Tuesday cancelled or delayed. Nats, the air traffic control provider, has said that recovery from the incident is "taking longer than hoped."

Heathrow, Manchester and East Midlands airports are among those that reported significant disruption, while airports in Scotland and Ireland have also experienced delays. Some airports say they are expecting a full schedule of flights to run on Wednesday, but warn of airports being busier due to rescheduled flights.

Ryanair says 65,000 of its passengers have been delayed by up to eight hours, while British Airways warns of a "significant knock-on impact for customers and colleagues." There's now a backlog of flights and aircraft across Europe in the wrong place - sorting all of this out will take time, writes our correspondent.

Bristol Airport says flights are now arriving and departing, but disruption is likely to continue into tomorrow. Heathrow Airport says arrivals have been suspended for the remainder of the day to ensure safety, while departures have resumed. Manchester Airport expects a "full flight schedule" on Wednesday, but warns disruption will continue for the rest of the day.
