The Return of Cultural Objects (Revocation) Regulations 2018
This instrument will revoke the domestic regulations which implement EU Directive 2014/60, relating to the return of cultural objects unlawfully removed from the territory of EU Member States, so avoiding a one-sided obligation upon the UK to return cultural objects, in the event of 'no deal' with the EU upon exit.
