The recent case raises questions about the effectiveness of the agreement between Britain and France.
A second migrant sent back to France under the United Kingdom's 'one in, one out' deal with Paris has returned to the UK, officials announced on Monday.
This development casts doubt on the scheme's efficacy, which aims to deter the influx of migrants arriving by small boats across southeast England.
The individual was swiftly detected upon re-entry through biometric systems and detained by authorities.
According to a Home Office spokesperson, his case will be expedited, and he will promptly be returned to France.
This incident follows closely on the heels of an Iranian asylum seeker who re-entered Britain via a small boat on October 18th, just over a month after initially being deported to France.
He was deported again last Wednesday, marking a concerning pattern under the new agreement.
The 'one in, one out' deal, agreed upon by Prime Minister Keir Starmer and French President Emmanuel Macron in September, enables the UK to deport certain arrivals deemed without a right to remain.
In return, the UK commits to accepting an equal number of migrants from France who are expected to have their asylum claims granted, with priority given to nationalities most vulnerable to smuggling operations and those with ties in Britain.
Despite these efforts, 94 individuals have been removed from the UK under this treaty, while 57 have arrived through official channels.
Critics argue that the arrangement is unfair towards migrants, with many rights groups condemning it for its potential impact on vulnerable populations.
In response to criticism and recent developments, Downing Street maintains that the scheme remains effective, arguing that those attempting to cross the Channel are aware of the risks and will be returned to France, thereby incurring a financial loss for their endeavors.
The number of migrants arriving by small boats this year has exceeded 39,000, marking an increase from previous years but remaining lower than the record set during the Conservative government's tenure.
This situation has contributed to rising support for anti-immigrant sentiments, bolstering parties like
Nigel Farage's Reform UK.
