The UK has closed all its “travel corridors” with other countries in an attempt to stem the spread of new CCP virus variants into the country.
Travellers must also transfer immediately into isolation upon arrival. The isolation period lasts for 10 days, unless the passenger tests negative after five days.
Johnson said the government had to take additional steps to protect the country against “the risk of as yet unidentified new strains” coming from overseas which might turn out to be resistant to vaccines.
“What we don’t want to see is all that hard work undone by the arrival of a new variant that is vaccine busting,” he said.
Transport Secretary Grant Shapps said on Friday that all travel corridors must now be closed because “it’s impossible for the Joint Biosecurity Centre to provide live scientific updates to predict which countries or regions will now originate new variants.”
The UK government coordinated with all devolved administrations in Scotland, Wales, and Northern Ireland so that the change applies across the whole of the UK.
“I think there is a challenge in its work abilities and deliverability, but we need to look at that very carefully based on the experience of other countries,” he told the BBC’s “Andrew Marr Show” on Sunday.
The government said on Saturday that it is setting up a financial support scheme to help airports through the new travel restrictions.
