The amendments update interpretations of relevant UN resolutions, modify the scope of prohibited trade in nuclear and missile-related items, and introduce specific exceptions to asset freeze and financial prohibitions to facilitate the satisfaction of obligations owed by the Treasury concerning Treasury debt, ensuring these actions remain compliant with the new sanctions framework.

The Aviation Security (Amendment) (No. 2) Regulations 2025, effective October 31, 2025, amend existing UK aviation security legislation.

The changes aim to streamline the merger review process while addressing concerns around foreign influence.

These criteria include possessing leave to enter or remain in the UK, not being subject to a 'no recourse to public funds' condition, and not being sponsored under certain visa schemes
