Unions, port officials and the French authorities blamed Brexit on Saturday as thousands of holidaymakers faced long delays trying to reach Europe via the English Channel port of Dover.
But U.K. Foreign Secretary Liz Truss laid the blame squarely on Paris, telling her French counterpart, Catherine Colonna, that “the French authorities have not put enough people on the border.”
The situation has added to the bad blood between London and Paris in the wake of Brexit, scotching hopes of a reset after Boris Johnson said earlier this month he was stepping down as premier.
“We need to see action from them (the French) to resolve the terrible situation which travelers, including families, are facing,” said Truss, who is currently fighting to succeed Johnson as prime minister.
But Paris has rejected claims that the gridlock was caused by under-staffing and Colonna in her tweet took a more sanguine view of their conversation, describing the talks as “good” and welcoming the “cooperation” to reduce the delays.
Colonna also underlined the “need to improve facilities at the Port of Dover.”
Tweeting the front page of Britain’s right-wing Daily Telegraph which had the headline “Truss tells France to fix holiday chaos,” French Transport Minister Clement Beaune said the French authorities were “mobilized” to ease movement.
But in a jab at London, the former Europe minister added: “France is not responsible for Brexit.”
Border checks and extra paperwork for freight traffic were reintroduced when Britain left the European Union last year, ending free movement for people and goods in the bloc.
Bottlenecks of lorries at Dover have been seen since then but this summer is the first with unrestricted travel for the public since the lifting of all COVID-19 restrictions.
French lawmaker Pierre-Henri Dumont, whose constituency includes the French Channel port of Calais, called the travel chaos “an aftermath of Brexit.”
“We have to run more checks than before,” he told BBC television, predicting it would happen again.
Port of Dover chief executive Doug Bannister initially blamed a lack of French border agency staff for the logjam which saw some holidaymakers wait six hours or longer to catch their ferries.
But he conceded there were now “increased transaction times” post-Brexit. The port was confident of handling the demand at peak periods, he added.
Brexit figurehead Johnson made “taking back control” of U.K. borders a rallying call for his “leave” campaign in the 2016 vote on EU membership.
Since becoming prime minister, he has found that more difficult, with record numbers of migrants crossing from northern France in small boats.
Lucy Moreton, from the ISU union that represents borders, immigration and customs staff, said the tailbacks were a “reasonably predictable” result of Brexit.
“This is the time that it’s chosen to bite,” she told the BBC.
Passengers have to go through both UK and French border checks at Dover before boarding ferries to northern France.
By 12:45 pm (1145 GMT), the Port of Dover said more than 17,000 passengers had already gone through.
Bannister said some 8,500 vehicles had left the port on Friday, with about 10,000 expected Saturday.
Queues for the port snaked through Dover and surrounding roads, stretching kilometers, with lorries backed up the M20 motorway leading to the town.
A traffic management system was rolled out on the M20 to manage the high volume of lorries backed up toward Dover.
That included closing parts of the motorway to non-freight traffic and diverting cars towards the port and the Eurotunnel by other routes.
The prefect of the Hauts-de-France region Georges-Francois Leclerc said France had “done its job” by increasing its border staff in Dover from 120 to 200.
He blamed the traffic jams on an accident on the M20 on Friday for the late arrival of French border agency staff at their posts in Dover.
All French staff were in position at 9:45 a.m. (0845 GMT) instead of 8:30 a.m., the prefect told reporters in Lille.
“Who would have thought that because the French reinforcements were an hour late that it would derail the whole system?” he added.
“Last year there was COVID. We’re finding out about Brexit” and its impact on peak periods. “The world has changed. The U.K. is now a third country to the EU,” which means much more time-consuming checks.
