France has confirmed the first case in the country of the more contagious coronavirus variant recently identified in the UK.
The French health ministry said the person was a French citizen in the central town of Tours who had arrived from London on 19 December.
The ministry said he was asymptomatic, and currently self-isolating at home.
The appearance of the new coronavirus variant in England triggered travel curbs with dozens of countries.
France closed its border but ended its ban on Wednesday, providing people tested negative before travelling. Thousands of lorry drivers spent Christmas Day in their cabs in Kent waiting to cross the English Channel.
