France has hit out at a Reform UK plan to return migrant boats using the Navy, saying the proposals would violate its sovereignty and breach international law. Nigel Farage's party announced that if it was in power it would intercept boats crossing the English Channel and return migrants to French ports, even if France disagreed. The spokesperson added: "Humanitarian missions do not violate maritime or international law." In a policy document, the party argued the plan would be legal under international law because it would be protecting the lives of migrants in dangerous boats. Yusuf accepted the plan could trigger a "diplomatic argument" with France, but insisted it had a "commitment under international law" to process migrants.
