A power failure has affected a major holiday airport as travellers move off for the Christmas holidays.
The failure is at Stansted airport in Essex and has affected a satellite building and the track transit which takes passengers to the satellite for boarding.
Stansted said neither the main terminal nor the runway were affected and that passengers were being taken by bus to their flights.
It is not yet known whether the power outage will lead to delays.
On Christmas Eve last year a power failure caused by flooding at Gatwick airport in West Sussex led to severe delays and a number of flight cancellations.
As efforts continued to restore power, Stansted reported that flights were operating, but with some delays.
