More than 40 countries have banned UK arrivals because of concerns about the spread of a new variant of coronavirus. Flights from the UK are being suspended to countries across the world including Spain, India and Hong Kong.
Boris Johnson said he spoke with French President Emmanuel Macron and both sides wanted to resolve "these problems as fast as possible". The prime minister told a Downing Street press conference: "We had a very good call and we both understand each other's positions."
Mr Johnson, who earlier chaired a meeting of the government's emergency committee, added: "We are working with our friends across the Channel to unblock the flow of trade."
European Union member states met earlier in Brussels to discuss a coordinated response, with officials suggesting a requirement for tests could be imposed on all people arriving from the UK. Eurotunnel services to France are also suspended and Eurostar trains to Belgium are not operating.
Health Secretary Matt Hancock has warned that the new variant of the virus - which may be up to 70% more transmissible - is "getting out of control". The new variant has spread quickly in London and south-east England, but health officials say there is no evidence that it is more deadly or would react differently to vaccines.
The only journey they're being told to make is to the back of the ever-growing queue that makes up Operation Stack. That will mean spending tonight, and all day tomorrow in their cabs - when all they want to do is get back home. It's a depressing situation in the run-up to Christmas. And if France does insist that all drivers need to be tested before being allowed to cross the Channel, it's likely some won't make it back before the big day.
