(BBC) – Anyone arriving in the UK from abroad could be fined £1,000 if they fail to self-isolate for 14 days, the government is expected to announce.
Under the plans, health officials would be able to carry out spot checks to check whether people were complying.
The new rules, which will also apply to British people returning from abroad, are not expected to come into force until next month.
Home Secretary Priti Patel will give more details at the daily briefing.
As part of the plans, which are aimed at guarding against a second wave of coronavirus infections, all arrivals would be asked to fill in a form with their contact information.
Road hauliers and medical officials would be exempt, as well as those arriving from the Republic of Ireland.
However, people travelling from France will not be exempt, the government has previously confirmed, after it was initially suggested otherwise.
Any passengers arriving in the UK by plane, ferry or train would need to provide UK Border Force officials with an address where they will self-isolate, otherwise accommodation will be arranged by the government.
Northern Ireland Secretary Brandon Lewis said: “The reality is we are saying to people if you are going to go abroad you need to look at the fact you may well need to do quarantine when you come back.”
Shadow health secretary Jonathan Ashworth backed the plans, but said there were “lots of questions as to why we didn’t do this sooner”.
He added: “I would urge the government to get on with it and give us the details about how it’s going to work in practice.”
Many other countries already require arriving passengers to enter a 14-day quarantine, including New Zealand, South Africa, South Korea, Spain and the US.
