Earlier this week, Heathrow’s chief solutions officer, Chris Garton, told the government’s transport committee the queues at the airport caused by additional Covid-19 checks at the border were becoming "untenable".
Garton said, on occasion, police had to be involved, and stressed the problem would become significantly worse if the government does lift restrictions on international travel from 17 May.
Despite just 10,000 to 15,000 people currently arriving at the airport, Britain’s busiest, every day, more than half were currently having to queue for in excess of two to three hours.
