Oodles of diplomatic energy have been expended on the unlikely relationship between the former human rights lawyer, Sir Keir Starmer and the former real estate magnate turned reality TV star, Donald Trump.
It was a political double act that long appeared unlikely and, for a while at least, appeared much stronger than many would have anticipated.
It doesn't look quite so strong any more, after President Trump belittled and mocked the Prime Minister publicly, comparing him, deeply unfavourably, with the UK's most celebrated wartime leader, Winston Churchill.
But hang on a second. It is worth seeing all this with some historical context.
It was Churchill, after all, who first talked 80 years ago this week of the so-called "special relationship" between the UK and America.
