Passengers flying into Heathrow Airport could be quarantined for 14 days to stop the spread of coronavirus, it has been reported.
According to the Mail on Sunday ministers agreed for new lockdown plans for passengers entering the country to be drawn up, which could begin next month.
Imposing large fines and even criminal prosecution are among initiatives being considered under powers linked to the Coronavirus Act.
And authorities could visit addresses of arrivals to the country to check they are not breaching the ordered self-isolation period.
It is hoped new measures will stop a second wave of the deadly disease as countries around the world begin to relax travel restrictions.
A Government source told the paper: “A stringent, Singapore-style approach at our ports will help the UK manage the risk from travellers entering the country and reduce the possibility of a second peak.
“We are looking at deploying these measures at the right time, in line with the scientific advice and when community transmission has been significantly reduced.”
