The flying of drones has been restricted in the vicinity of the Port of Dover because of national security concerns.
Legislation came into force on November 1 and bans drone use below 1,000 feet above mean sea level, within a 2.25 nautical mile radius.
The new regulations say: “The Secretary of State has decided that it is necessary in the public interest to restrict the flying of unmanned aircraft in the vicinity of the Port of Dover, Kent owing to its status as critical national infrastructure and its associated national security risk.”
Exempt from the restrictions are Port of Dover Police, Kent Police, Kent Fire and Rescue Service, balloons and kites and any unmanned aircraft operating with the permission of the Port of Dover Police.
