Boris Johnson, first as foreign secretary and then prime minister, has like many Western leaders faced two competing goals when dealing with Donald Trump.
The first is to convince the US president to change his mind on a raft of foreign policy issues where he is out of step with the post-Second World War consensus.
Diplomats widely agree Mr Trump sees world affairs through the prism of personal relationships and is open to flattery, so the aim is to get close and influence his thinking.
But the second challenge makes that much harder – keeping the domestic public on side and pushing back when he is deemed to have overstepped the mark.
Britons, like most Europeans, overwhelmingly have a negative view of the US president, according to opinion polls, and opposition parties are ever willing to take advantage.
So how do you walk that line? The leaked notes detailed in this newspaper shed light on part of Mr Johnson’s approach – give effusive praise of the president behind closed doors.
