Negotiations have been going on for months and an agreement is due to be unveiled today. Details of the plan, first revealed by the Daily Express at the weekend, come as official figures show more than 40,000 people made the deadly crossing so far this year – up from 28,526 in 2021.
Many are Albanians, with others coming from Afghanistan, Iran and Iraq.
The expanded agreement includes an increase in payments from London to Paris and a much closer relationship between border policing teams.
Home Secretary Suella Braverman is expected to be in the French capital today to sign the deal alongside French interior minister Gérald Darmanin.
The multimillion-pound plan will represent one of the largest sums ever handed over to the French by British taxpayers.
A French diplomatic source said the UK’s annual contribution to policing the border will rise from around £54million last year to just above £62million.
“The focus will be on breaking up the people smuggling gangs, using better surveillance, including more drones,” they said.
A government source hailed the deal as a “good step forward” but added: “It needs to be followed up with a broader deal.”
