British police assured today that they are preparing for “almost every predictable scenario” ahead of U.S. President Donald Trump’s official visit to the country this week.

Trump arrives in Britain tomorrow for a historic second official visit, which begins the following day, with the British palace hosting the U.S. president for, among other things, a carriage tour and a lavish state dinner.

“This is a major policing and security operation, as would be expected for an official visit of the U.S. president,” Deputy Chief of Thames Valley Police Christian Bunt told reporters.

The royal portion of Trump’s visit will take place at Windsor Castle in west London, the oldest and largest inhabited castle in the world, which has been the residence of British monarchs for 1,000 years.

British Prime Minister Keir Starmer will then welcome Trump on Thursday at his country residence at Chequers.

The significant trip comes following last week’s murder of right-wing activist Charlie Kirk, a loyal Trump ally, which has sparked fears of rising political violence in the U.S.

Asked whether Kirk’s murder had affected the policing plan for the visit, Bunt said the planning is under constant review.

“I am satisfied that we have planned a very comprehensive policing and security operation that takes into account almost every eventuality of what might happen,” he said.

According to the officer, the visits to Windsor and Chequers will be private, thereby limiting the president’s exposure to the public.
