Trump’s second summit with Kim Jong-un, in Hanoi, Vietnam, did not go to plan. As negotiations over North Korea’s nuclear programme broke down, Trump left abruptly, saying to the press: “Sometimes you just have to walk.”

But before he departed, the then US president did make one astonishing offer to Kim.

Matthew Pottinger, the top Asia expert on Trump’s National Security Council told us: “President Trump offered Kim a lift home on Air Force One. The president knew that Kim had arrived on a multi-day train ride through China into Hanoi and the president said: ‘I can get you home in two hours if you want.’ Kim declined.”
