Boris Johnson has been accused of deriding Franco-British relations and told he must “take responsibility” for the migrant crisis following the fallout last week.
French Interior Minister Gerald Darmanin said the Prime Minister had acted “in a special way” by choosing to post on Twitter a letter to French President Emmanuel Macron outlining his proposed solutions for small boat crossings in the English Channel.
Counterparts from France, the Netherlands, Belgium and the European Commission met in Calais on Sunday, but neither Home Secretary Priti Patel nor British officials were present after learning they were not were not welcome.
The Prime Minister’s letter to Mr Macron came after a dinghy capsized in the Channel Sea on Wednesday, killing 27.
Mr Darmanin said the British leader had sought to make fun of France by, according to the minister, urging Paris to “take back its migrants”.
Speaking to BFMTV, Mr. Darmanin said: “When there are serious diplomatic exchanges… and lives that are at stake… and a few minutes later you see a letter, which no one has ever mentioned previously, is posted on Twitter by the British Premier. Minister to the President of the French Republic before the President of the Republic received him, it’s a bit special.
“When in this letter the English say that the French should ‘take back their migrants, all their migrants’, it is a parody. “
He added that Franco-British relations were currently not “normal” and that “our private exchanges are not always in phase with our public exchanges”.
The senior French politician also tweeted on Monday, urging the British government to “take responsibility” for the migrant crisis.
Number 10 has previously sought to play down talks about a bilateral breakup.
After talks on Sunday, it was agreed that a plane, operated by the European Union border agency Frontex, would monitor the shores of the English Channel for people crossing from December 1.
Migration officials have also pledged to cooperate more closely against smuggling networks and the inflatable boat trade.
Ms Patel would have been satisfied with the decision to send the Frontex plane.
Among those dead after Wednesday’s tragedy were a pregnant woman, children and a 24-year-old Kurdish woman from northern Iraq trying to locate her fiance.
This is the highest death toll ever recorded in the current crisis.
