The National Security and Investment Act 2021, which was passed on 29 April 2021, comes into force today. The new regime, which subjects investments in many companies active in the UK to mandatory review on national security grounds, will be among the most wide-ranging in the world. It represents the most significant change in the UK regulatory environment since the Government ceded the power to approve or prohibit mergers on competition grounds to an independent agency in 2002.
