Question to the Home Office:

To ask the Secretary of State for the Home Department, how many (a) pre-action protocol letters, (b) judicial review applications and (c) injunction requests have been received relating to the one-in, one-out migrant returns scheme agreed with France since 1 July 2025.

The UK-France Treaty is an innovative pilot designed to deter illegal migration across the Channel. Litigation related to this pilot was anticipated and we are concentrating resources on robustly defending this so that removals can continue as planned. As of 7 November, 94 individuals have been returned to France through this agreement.

The Home Office maintains records on legal challenges. Operational details on the pilot are sensitive, and we will not be disclosing such information as it could inadvertently assist the organised immigration crime gangs that are behind small boats crossings.
