Passengers arriving into Heathrow Airport experienced more misery today as queues snaked for ‘a quarter of a mile’ at Terminal 5.

Photographs taken by frustrated passengers showed congested corridors as people waited to reach immigration desks.

It is not the first time the airport has been log jammed. BTA chairman Clive Wratten told Travel Gossip of ‘mega queues’ last October after e-gates stopped working.

It was not immediately clear what caused today’s chaos which, according to reports, left people waiting ’hours’ to reach immigration.

Several passengers tweeted their irritation along with images of the mayhem.

One said: “The immigration queues are once again a nightmare with passengers (including a few elderly) on their feet for hours. Will this structural issue at the #borderforce ever be properly addressed?”

According to The Sun, former MP and Member of the House of Lords Richard Benyon was caught up in the chaos.

He tweeted: “I’m in a queue about a quarter of a mile long at Heathrow. No one telling us about what the problem is. No staff on hand at all. Welcome to Britain.”

Heathrow said queues built up in the early morning but had cleared and were ‘back to normal’ by around 9am.

A spokesperson said: “Earlier today we experienced some delays processing passengers through the UK border in T5. Our teams were on-hand to support passengers in the immigration halls and we worked with Border Force to resolve the situation as quickly as possible. We apologise for any inconvenience caused.”
