United Kingdom–France one in, one out plan

The United Kingdom–France one in, one out plan is an agreement between the United Kingdom and France aimed at reducing unauthorised migration across the English Channel into the United Kingdom. Formalised in August 2025, the plan states that migrants that arrive illegally by small boats to the UK can be sent back to France. In return the UK will take the same number of migrants from France who have not tried to cross the Channel before and pass security and eligibility checks.
