In the run-up to Prince Harry and Meghan Markle's much-anticipated royal wedding, the local Thames Valley Police (TVP) force knew that it had to make this high-profile event as secure as possible. The same security level would have to be maintained for Princess Eugene and Jack Brooksbank's royal wedding five months later, located at Windsor Castle. The police knew that both events would carry significant risk to the attendees and the general public without full security measures. Therefore, the police had to ensure that threats would be identified as soon as possible, before, after, and during the events. In fact, it was estimated that the security operation cost was in excess of $41,701,500, or £30 million, becoming one of the biggest UK operations ever.
