President Macron and Prime Minister Boris Johnson spoke on Monday, and it is understood that the French side gave an undertaking to find a rapid solution to the blockage.
Most likely it will include compulsory negative Covid tests for lorry drivers coming into France from the UK, and authorisation for European nationals wishing to travel home from the UK for Christmas.

Testing lorry drivers for coronavirus is a "necessity", the president of the Port of Calais says.
Jean-Marc Puissesseau, who is president and chairman of the ports at Calais and Boulogne, said he hoped testing could start "very soon" and hoped a solution could be found in a matter of hours to the closure of the border.
He told BBC News: "I do hope really that something will be found and the hauliers will be able to spend Christmas at home."
He said 1,200 lorries had travelled from Calais to Dover on Monday with a further 600 making the journey as of midday.
