This Bill amends the Terrorism Act 2000 and makes further provision for terrorism and national security. It establishes powers to freeze assets, strengthens immigration and asylum measures, extends criminal offences and investigatory powers for preventing and enforcing crime, and provides for the control of pathogens and toxins and the retention of communications data. It also provides for implementation of Title VI of the Treaty on European Union and contains related consequential provisions.

The measures enhance prevention, investigation and enforcement and impose compliance obligations on public bodies, financial institutions and carriers. They introduce authorisations, disclosure and retention requirements, oversight and review mechanisms, and potential expanded sanctions; practitioners should note the increased operational powers, data‑handling duties and cross‑border co‑operation implications.
