Boris Johnson is expected to approve plans to force some travellers arriving to the UK to quarantine in hotels to limit the spread of new coronavirus variants.
The British Prime Minister will discuss proposals for arrivals to quarantine in designated hotels to ensure they follow self-isolation rules with senior ministers.
Various options are said to be on the table, but Whitehall sources suggested that ministers may opt for a more limited system.
It comes after aviation leaders warned that introducing tougher border rules would be "catastrophic" for the industry. The officials said a less sweeping option would apply only to British residents returning from countries with more contagious strains, such as Brazil, South Africa and Portugal.
