A power outage has affected flights at Stansted Airport.
The problem, which was part of a general loss of power in the area, led to delays to outgoing and incoming flights at the Essex terminal.

Some flights may still be subject to delay or cancellation. Passengers are being advised to check the status of flights with their airline.
