Anyone travelling into the UK from abroad could be required to produce a negative coronavirus test as part of new tightened restrictions.
Ministers are understood to be mulling over toughening border controls ahead of a third national lockdown, though hauliers would be exempt, according to reports.
The negative result would need to have been obtained no more than 72 hours before departure, and a second test could then be required on arrival.
Under current rules, new arrivals must only fill out a passenger locator form before quarantining if traveling from a country not on the Government's 'travel corridor' list.
