The 14-day quarantine rule for travellers to the UK has no firm end date - and will instead be reviewed every three weeks, the government confirmed today.
The news will be a blow to airline bosses, who believe they will be crippled by laws on almost everyone arriving in the UK - including returning Brits.
Within days people arriving from any country except Ireland will soon have to isolate for two weeks - with exemptions only for some people like lorry drivers or scientists.
Critics have blasted the government for only introducing quarantine months after the outbreak was imported to the UK. But airline chiefs have warned the quarantine will devastate their business with Ryanair's Michael O'Leary branding it "idiotic" and "unimplementable".
