Nov. 10 (UPI) — The British government on Monday said a person who was removed to France recently returned to Britain with a small boat of migrants, the second return of a migrant deported under the so-called “one in, one out” arrangement with France.

The Home Office said the man was part of a group of nearly 400 people who crossed the Channel from France to Britain on Sunday. Officials used biometrics to determine the man was one of 94 people who had been removed to France over the past two months, The Guardian reported.

Immigration officials first removed the man to France less than a month ago, The Independent reported. The Home Office said he will be sent back to France again “as quickly as possible” under an expedited process.

“Anyone looking to return to the U.K. after being removed under the UK-France agreement is wasting their time and money,” a spokesperson for the Home Office said. “The message is clear: If you try to return to the U.K. you will be sent back.”

A spokesperson for Prime Minister Keir Starmer said the news is “evidence of the system working.”

“He was immediately detected at the front door, thanks to those biometrics being taken,” the spokesperson said.

Starmer and French President Emmanuel Macron agreed to a deal in July that would see the two countries exchange migrants on a one-to-one basis. France would accept the return of one migrant who arrives without permission in Britain in exchange for each migrant with a legal asylum claim that Britain takes in.

The agreement went into effect Aug. 6, and the first removal took place in mid-September.
