The first migrants to arrive in the UK after crossing the English Channel have been detained under the new "one in, one out" deal. The detentions came as people arrived in Dover on Wednesday, the first day the pilot scheme came into force. Pictures showed the migrants wearing life jackets disembarking from Border Force boats.

Migrants arriving off Britain's south coast were being taken into detention ahead of their removal back to France under a new reciprocal cross-Channel treaty.

The UK has detained the first small-boat migrants under a “one in, one out” returns treaty with France, as pressure grows on Prime Minister Keir Starmer to stem the influx of asylum-seekers across the English Channel.
