Humans for Rights Network also says some returned under ‘one in, one out’ scheme had family in the UK

The first group of asylum seekers removed to France under the “one in, one out” scheme includes potential victims of modern slavery, people suffering severe depression and those with family in the UK, a new report has found.

Humans For Rights Network (HFRN) interviewed those returned after crossing the Channel in small boats in mid-October while they were staying in their initial accommodation – a marquee next to a railway track in Paris.

The research was announced after the Guardian revealed that an Iranian asylum seeker, who was sent to France last month, returned to the UK just 29 days later and is being held in an immigration detention centre.

He has been referred to the national referral mechanism to investigate a claim that he is a victim of trafficking. The prime minister said on Thursday that the government was planning to expedite the man’s return to France.
