First migrants detained under 'one in, one out' deal with France

The UK detains first migrants under 'one in, one out' deal with France as Border Force vessels bring intercepted migrants into Dover port. Home Secretary Yvette Cooper signals readiness to resist legal challenges against the removal of these migrants and emphasizes that anyone arriving is eligible for immediate detention and return under the pilot scheme. The scheme aims to deport migrants crossing the English Channel and involves reciprocal asylum seeker transfers between the UK and France, with a focus on quick referral processes for returns and approvals for safe routes.
