A power surge at Stansted Airport has caused hundreds of flights to be delayed.
Passengers at the airport in Essex have been left queuing for hours after the power supply problem caused security and baggage systems to go down.
Some 250 flights were delayed on Sunday, with six cancelled, according to flight tracking data from Flightradar24.
Stansted Airport said all their systems were operational again by the evening and apologised to travellers affected.

"All systems are now back in service with operational teams working hard to provide support to passengers on their journeys through the airport.
"We thank passengers for their patience and apologise for any disruption and inconvenience they may have experienced while services were being restored."
