WATCH: Donald Trump delivers blunt verdict on Andy Burnham

He admitted: "I don't know anything.

"I see that he was, I guess, the mayor of a town? I hear he's extremely liberal."

Discussing the state of the oil industry in the UK, the President revealed he has had "every oil company come to see him" about having "access to the UK", declaring that Britain is "dying".

He said: "I have had every oil company come to see me. 'Sir, could you give us access to the UK? We would do anything to drill in the North Sea'.

"The amazing thing is they buy their oil from Norway, which gets the offer of the North Sea. Think of it, and they pay a big premium.

"Norway's got now $2trillion in the bank and UK is dying, so they should open up the North Sea, and it's an easy one. And a lot of good things are going to happen."
