EVERYONE entering the UK from abroad will be required to self-isolate upon arrival from next week, the Prime Minister has announced.

Boris Johnson revealed the measures in a press conference this evening, Friday, in a bid to prevent new strains of the coronavirus entering the country.

The PM stated that "all travel corridors" into the UK would be temporarily shut from 4am on Monday, January 18.

This means that anyone entering the country must have proof of a negative Covid-19 test taken in the 72 hours before departure.

They must also fill in a passenger locator form, with proof of both required before take-off.

Travellers must quarantine for 10 days after their return, with a further test to be taken on the fifth day.

"Substantial" fines will be dished out for failing to comply.

Mr Johnson said during the briefing: “It would be fatal if this sense of progress would breed any sort of complacency, because the pressures on the NHS are extraordinary.

“This is not the time for the slightest relaxation of our national resolve and individual efforts.

“It’s precisely because we have the hope of that vaccine and the risk of new strains that we must take additional strains from entering the country.”
