The Air Navigation (Restriction of Flying) (The Mall) (Emergency) Regulations 2026 enact immediate, temporary prohibitions on the operation of unmanned aircraft below 1,250 feet above mean sea level within a 1.25 nautical mile radius centred on The Mall in Harrow, valid for April 20, 2026, between 11:59 and 23:59 hours, unless specific permission is granted by the Metropolitan Police Service.

These Regulations, made by the Secretary of State under the Investigatory Powers Act 2016, amend Schedule 4 of that Act to remove specific ambulance service trusts in England and Northern Ireland from the list of relevant public authorities permitted to obtain communications data, thereby revoking their statutory power to access such data as of May 11, 2026.
