It is never a minor affair when the President of the United States visits the UK. Although this has been billed as a short working trip, the key ingredients pointing to its underlying significance are all there: a meeting with the Queen, tea at Chequers, a Special Forces exercise.
There is a reason for this rolling out of the red carpet. From the start, Theresa May has been careful not to align herself too closely with Paris, Berlin and Brussels as they have made their distaste of President Trump known. She has taken significant political flak through her positioning as a friend and ally of the US.
Now, with the UK visit coming between the rock of the Nato summit and the hard place of President Trump’s one-to-one with Vladimir Putin of Russia, she will hope that her efforts reap a diplomatic and economic reward.
