The government is expected to announce random spot checks on international arrivals and £1,000 fines for non-compliance as it unveils its quarantine plans on Friday.
The home secretary Priti Patel is due to host the government’s daily briefing at 5pm.

Quarantine on arrivals to begin in early June, says transport secretary
The BBC reports that all arrivals will be asked to complete a form with their contact information when the measures are introduced next month.
The government has already announced that arrivals from the common travel area including the Republic of Ireland will be exempt, with road hauliers and medical officials also not expected to be included.
The government is due to review the plans to enforce 14-day isolation on arrivals every three weeks, but many in the aviation industry have criticised the move as unnecessary and said it will effectively kill international travel.
The Northern Ireland secretary Brandon Lewis defended the timing of the quarantine introduction.
He told Sky News: “As the virus spread is falling here in the UK, as our R number is falling, that marginal impact of people coming in has a real effect in a way that it just didn’t a few weeks ago. And some weeks ago, we were still returning many Britons back to the United Kingdom.
“People who come over to the United Kingdom will have to do quarantine and a few countries around the world are looking at this or have already introduced this. As our R number is down we want to ensure that we don’t get that second spike that could be one of the most damaging things for our economy in the long run.”
Lewis also said there were “no plans at the moment” to develop air bridges to allow reciprocal travel between specific countries, a development previously suggested by transport secretary Grant Shapps.
