Sorry to have been out of touch the past few days, but your correspondent has been traveling with Big Don.
Not entirely a success, but it might have been worse. It's true his white waistcoat was too long with his tails at the Royal dinner, but I did talk him out of wearing his Make America Great Again tee shirt. And when the Champagne toasts were raised, I managed to cancel his Diet Coke.
It was unfortunate that he wanted to demonstrate some Sumo moves to Her Majesty, but everyone cheered when she defeated him at arm wrestling.
And that was that for the President's UK state visit, apart from offering Theresa May a job at one of his golf courses and meeting Boris Johnson to compare hair.
More notes to come.
