On 20th March, the Home Office published guidance on the Counter-Terrorism (Sanctions) (EU Exit) Regulations 2019, which is intended to assist people in implementing and complying with the Regulations. It covers the prohibitions and requirements imposed by the regulations. It also provides guidance on best practice for complying with the prohibitions and requirements, enforcing them, circumstances where they do not apply. The guidance should be read alongside more detailed sanctions guidance published by OFSI.
