The French government has announced, people arriving in France from the UK will have to self-isolate for 14 days from 8 June,.
It comes after Home Secretary Priti Patel revealed quarantine plans for visitors to the UK from the same date.
France said it would impose reciprocal measures for any European country enforcing a quarantine.
Travellers arriving in France from Spain by plane will also be asked to go into quarantine from Monday.
Speaking at Friday’s Downing Street briefing, Ms Patel said travellers to the UK will need to tell the government where they will quarantine, and face enforcement through random spot checks and £1,000 fines in England if they do not comply.
She said the measure would “reduce the risk of cases crossing our border”.
Lorry drivers, seasonal farm workers, and coronavirus medics will be exempt.
The requirement will also not apply to those travelling from the Republic of Ireland, the Channel Islands and the Isle of Man.
If a person does not have suitable accommodation to go to, they will be required to stay in “facilities arranged by the government” at the person’s own expense, according to Border Force chief Paul Lincoln.
The Home Office said the new policy will be in place across the UK, although how it is enforced in Scotland, Wales and Northern Ireland will be determined by the devolved administrations.
Scotland’s First Minister Nicola Sturgeon said discussions would take place with Police Scotland to work out how the policy will be implemented.
