<h1>Home Secretary unveils tougher immigration enforcement with Five Eyes visa suspensions, stricter borders, and human-rights concerns</h1> The new UK Home Secretary announced a tougher immigration enforcement strategy, signaling coordinated measures with Five Eyes partners including potential suspension of visas for states that refuse to accept returned nationals, and stronger border controls to curb small-boat arrivals and people-smuggling. The initiative emphasizes multilateral intelligence and operational cooperation on removals, online child exploitation and opioids, and contemplates using visa restrictions as leverage to compel readmission of migrants lacking legal status. The policy raises issues of international cooperation on returns, state obligations under immigration and human-rights law, and the use of diplomatic sanctions to enforce compliance.
