Security will be significantly increased in and around Windsor Castle next week as King Charles III hosts President Bola Tinubu and First Lady Oluremi Tinubu on March 18–19. The visit represents the highest level of diplomatic engagement the British monarchy can offer.
Thames Valley Police announced that extensive security measures will be in effect across Windsor, including a temporary extension of the existing airspace restrictions over the castle. On March 18, the no-fly zone will run from 07:00 to 23:59 GMT, coordinated with the Civil Aviation Authority.
Adrian Hall, chief superintendent of Thames Valley Police’s joint operations unit, said the airspace restriction is only one component of a broader security plan. “The air restrictions are just one part of our robust security operation for President Tinubu’s state visit,” Hall said. “Many measures will be visible, while others will not. Anyone breaching the restrictions could be committing a criminal offence under the Air Navigation Order and may be arrested.”
A substantial deployment of officers with specialist skills is expected across Windsor, including search teams, armed officers, mounted police, and roads policing units. Teams conducting unpredictable patrols will also engage with the public to deter and detect crime.
Authorities will make full use of Windsor’s CCTV network and hostile vehicle mitigation barriers to safeguard the event. “We have extensive experience policing royal events and have undertaken significant planning for this visit,” Hall added. “We will ensure the safety of dignitaries, spectators, and the public during this historic occasion.”
Several road closures and parking restrictions will begin on March 17, with temporary disruptions possible throughout Windsor. Footways and pedestrian crossings in the town center will also close periodically from 09:30 to 12:30 on March 17 and 18 to accommodate a ceremonial procession.
Police are urging residents and visitors to remain alert and report suspicious activity. “The public plays a critical role. Please call 101 for non-emergencies or 999 for immediate threats,” Hall said.
