Overview
- The one-for-one exchange commenced on August 5–6, 2025, swapping inadmissible small-boat arrivals in the UK with migrants from France approved through an online application platform.
- Each government plans to detain and transfer about 50 migrants per week during the pilot, subjecting all new arrivals to comprehensive security vetting.
- The European Commission backed the initiative as an innovative deterrent against Channel crossings and will conduct monthly evaluations of its performance.
- Northern French officials and migrant aid associations argue that the arrangement disproportionately benefits the UK and may breach international refugee protections.
- The agreement responds to a record 25,400 small-boat crossings so far this year and reflects mounting pressure on Prime Minister Keir Starmer from Reform UK and public protests.
