Travellers arriving at Heathrow airport in London are being forced to queue for up to six hours to pass through immigration controls, according to an airport executive.

Chief solutions officer Chris Garton has admitted “the situation is becoming untenable” and said the police have been forced to step in.

Footage filmed at Heathrow on April 14 showed huge queues of passengers who had arrived on a British Airways flight from Lahore at 6 am.

According to the filmer, Jhanzaib Sulari, he was made to wait in a small designated area for hours until finally reaching his quarantine hotel at 1130 am.

He said other passengers were still waiting at the airport when he left.

"They were checking passports, hotel bookings, passenger locator forms and COVID tests at every point," said Sulari.

"There was no coordination between the people who were managing all this," he added.

The British Airways flight from Lahore landed around 06:00 at London Heathrow Airport. After going through the immigration people were made to wait for hours in a small designated area. The reason given was that they didn’t have enough coaches to transport people from Airport to hotels to Quarantine. I was one of the passengers. I got to my hotel lobby at around 11:30am. There were people who were still waiting at the airport when I left. There was no coordination between the people who were managing all this.
