This is a man’s world. The airside tarmac, as Air Force One touched down in Shannon, was dotted in men. In a makeshift meeting room at Shannon Airport, US president Donald Trump and Taoiseach Leo Varadkar were flanked by their requisite back-up teams.

In the Irish corner was Mr Varadkar’s chief of staff, Brian Murphy; our most senior Brexit official, John Callinan; special US envoy John Deasy; and Ireland’s ambassador to America, Daniel Mulhall. In the American corner was Mr Trump’s own chief of staff, Mick Mulvaney, national security adviser, John Bolton; and secretary of the US Treasury, Steve Mnuchin. Big jobs.
