At 2.25am, Donald Trump gazed out at his jubilant supporters wearing “Make America Great Again” hats. He was surrounded by his wife, Melania, and his children, the Stars and Stripes and giant banners that proclaimed: “Dream big again” and “Trump will fix it!”

“We’re going to help our country heal,” Trump vowed. “We have a country that needs help and it needs help very badly. We’re going to fix our borders, we’re going to fix everything about our country and we’ve made history for a reason tonight, and the reason is going to be just that.”

Democratic strategist and former Republican congressional aide, said: “What we’re going to have is an imperial presidency. This is going to be probably the most powerful presidency in terms of centralising power and wielding power that we’ve had probably since FDR [Franklin Delano Roosevelt, who was president from 1933 until his death in 1945].”
