France is tightening Covid restrictions for travellers arriving from the UK, as the government in Paris tries to slow the spread of the Omicron variant.
The French prime minister’s office said that from Saturday travellers would have to give a compelling reason for coming to France.
All arrivals will have to provide a negative Covid test less than 24 hours old and isolate for at least two days.
If you have booked a skiing holiday, for example, you will not be able to come. That’s clear - all holidaying is out. If you are a UK citizen wishing to spend Christmas with your retired parents who live in France, it doesn’t look good either. The list appears to state that the only Britons allowed in are those with registered homes in France, plus transport workers and some students.
