Britain had no choice but to impose a 14-day quarantine on all arrivals from France from Saturday in order to protect public health domestically, transport minister Grant Shapps said on Friday.
"It's a dynamic situation, and I don't think that anybody... would want us to do anything other than protect public health and public safety," Shapps told Sky News.
"That does mean where we see countries breach a certain level of cases ... then we have no real choice but to act.”
Boris Johnson announced late on Thursday night that hundreds of thousands of British holidaymakers will need to quarantine when they return from France.
The Prime Minister decided to strip France from the “green list” after it reported a sharp rise in coronavirus infections.
About 400,000 Britons have until 4am on Saturday to return to the UK before restrictions are implemented, requiring them to self-isolate for two weeks.
