The abiding image from this year’s G20 summit will not be Donald Trump sharing another chuckle with Vladimir Putin. It is the clip of his daughter, Ivanka, inserting herself into an awkward circle of world leaders.

The video, released by the French government, shows varying expressions of tortured politeness as Ms Trump intrudes on a discussion between France’s Emmanuel Macron, Britain’s Theresa May, Canada’s Justin Trudeau and Christine Lagarde, head of the IMF. Ms Lagarde, in particular, was unable to conceal her irritation.

What they were discussing is secondary. Mr Macron made a point about social justice. Mrs May replied that people notice when the economy is brought into it. Ms Trump then interrupted with a non sequitur about how the defence industry is male-dominated. The real point is that America’s self-named “First Daughter” is rarely out of the frame at global summits. Other Trump officials are almost invisible compared with Ms Trump, and her husband, Jared Kushner, the only two White House players who are thought to be immune from Mr Trump’s trademark phrase: “You’re fired.”
