Passengers at Stansted Airport have faced "unacceptably long" immigration queues at the beginning of the Bank Holiday weekend.
Hundreds of disgruntled passengers were delayed for up to two hours at passport control at the Essex airport on Friday evening.
A spokesman for Stansted airport said action was needed to address the issue of long waits urgently:
"We recognise that maintaining strong border security is a priority but we also want to see sufficient resources available to meet passenger demand and keep delays to a minimum at the busiest times.
"Our customer service teams work closely with the UK Border Force to help manage queues and assist passengers at peak times but we believe further action is needed to address the issue as a matter of urgency."
