Airline passengers are tonight facing disruption after an IT glitch resulted in extended queues at immigration desks.
Lengthy queues have already started forming at airport terminals across the country after a fault on UK Border Force computers this afternoon.
Extra staff have been drafted in to try and reduce the queues.
A Government spokesman said:
We are currently experiencing temporary IT problems which may add to the time taken to conduct passport checks.
We are working to rectify this issue and are providing extra staff to get passengers through the controls as quickly as possible. Our priority remains security of the border.
We apologise for any additional time this adds to passengers' journeys.
