With regards to the upcoming state visit of the President of the United States 🇺🇸 to the United Kingdom.
If anyone actually saw the footage of Trump opening the letter presented by Starmer in the Oval Office, Trump was very impressed by the fact that it would be at Windsor, and he said so at the time.
So I should assume that the state visit or at least part of it will involve Windsor. This will inevitably affect STN. I can't imagine the official state visit being extended to Scotland. Although Trump may well visit Scotland on his own accord before he travels back to Washington. And this will more than likely involve PIK.
