The 25-year-old claims to be trafficking victim and won high court challenge in what may prove major blow to Labour policy

An Eritrean man has had his deportation to France under Labour’s “one-in, one-out” scheme halted at the 11th hour after he won a high court challenge.

The 25-year-old man, who cannot be named for legal reasons, is the first to win a challenge in the high court against the removal scheme, which is itself new. The first removal flights were due to take place on Monday and Tuesday of this week but were cancelled. The man had been due to be on a flight to France at 9am on Wednesday.

The judge, Mr Justice Sheldon, halted his removal after a decision came through during the court hearing that his claims to be a victim of trafficking required further investigation.

The ruling is a significant blow to the government because many of those due to be removed under the scheme are potential victims of trafficking. Because they have only recently arrived in the UK they have not had an opportunity to have their trafficking claim fully investigated nor to obtain expert medical and psychological reports.
