A Border Force IT failure has caused electronic passport gates to fail at airports across the UK.
Travellers including journalist Louis Theroux reported huge queues at Heathrow, Stansted, Edinburgh, Manchester airports and other locations.
A spokesperson for Heathrow airport, which is the busiest in the UK, said: “We’re aware of a systems failure impacting the e-gates, which are staffed and operated by Border Force.
“This issue is impacting a number of ports of entry and is not an isolated issue at Heathrow. Our teams are working with Border Force to find a solution as quickly as possible.”
A spokesperson for Edinburgh airport said there was a “nationwide” Border Force IT issue and officials were working to resolve it.
Recommended Home Office admits Heathrow queues ‘unacceptable’ as airport criticises Border Force over immigration checks Border Force carries out ‘pushback drills’ using jet skis to divert dinghies in Channel, footage suggests Heathrow boss accuses Border Force of ‘complacency’ as airport loses 6.2m passengers in April
E-gates allow travellers with biometric passports to pass through border control without a manual inspection.
Mr Theroux shared a photo of himself on Twitter, in what he called a “human logjam” at Heathrow.
Other passengers reported that their planes were being held on the tarmac because of the “nightmare queues” inside the terminal.
Some reported waits of at least two hours for passport control, and expressed concerns about overcrowding and a lack of protective measures for Covid.
The Home Office said an unspecified “technical issue” had caused the failure, and security at the border had not been affected.
A spokesperson added: “This afternoon a technical issue affected e-gates at a number of ports. The issue was quickly identified and has now been resolved.
