French President Emmanuel Macron on Thursday said Britain’s plan to send asylum seekers to Rwanda was “ineffective” and showed “cynicism”, while praising the two countries’ cooperation on defence.

“I don’t believe in the model… which would involve finding third countries on the African continent or elsewhere where we’d send people who arrive on our soil illegally, who don’t come from these countries,” Macron said.

“We’re creating a geopolitics of cynicism which betrays our values and will build new dependencies, and which will prove completely ineffective,” he added in a wide-ranging speech on the future of the European Union at Paris’ Sorbonne University.

British MPs on Tuesday passed a law providing for undocumented asylum seekers to be sent to Rwanda, where their asylum claims would be processed and where they would stay if the claims succeed.

The law is a flagship policy for Prime Minister Rishi Sunak’s government, which badly lags the opposition Labour party in the polls with an election expected within months.

Britain pays Paris to support policing of France’s northern coast, aimed at preventing migrants from setting off for perilous crossings in small boats.
