Piers Morgan always "has to win".

The 'Good Morning Britain' presenter triumphed on the 'Celebrity Apprentice' in the US in 2008 and admitted he did thorough research on President Donald Trump - who was head of the famous boardroom at the time - before taking part in order to maximise his chances of success.

He said: "Trump said, 'Piers, you were tactless, ruthless, aggressive, hard, possibly brilliant, and you knocked them all out one by one - you win.'

"I reminded him of that the other day, 'Ring any bells?'

"I played the 'Celebrity Apprentice' having read 'The Art of the Deal' twice to get inside his head.

"Even if it is tiddlywinks, I have to win.

"I got inside his head and I was almost Trump-like, and I won, and I watched the presidential race and he was doing the same things."

Despite facing criticism for his support of the controversial new US President, Piers insists he "genuinely likes" the commander-in-chief.

He told Alistair Campbell for Britain's GQ magazine: "I genuinely like him, I have known him through 10 years and saw from 'The Apprentice' he can be charming, funny, smart and his judgment is spot on.

"He loved drama and arguments and making the right decision and being popular."

However, despite their friendship, the 51-year-old broadcaster insists he could never work for Trump in the White House.

He said: "I couldn't work for an administration I don't believe in politically.

"I totally disagree with him on guns, climate change.

"[But] I expect to talk to him a fair bit. I consider him a good friend and loyal to me. I did a book about gun control, something he disagrees with me on.

"He said he couldn't come to the launch and then he and Melania walked in and he said, 'You didn't think I'd let you down, Champ.#

"When I left CNN, lots of people were done with him but not him, he kept calling.

"So give him a chance. He only has to deliver on jobs and the economy."
