Donald Trump book 'will end his presidency', says author of explosive Fire and Fury exposé

Michael Wolff says book has exposed a 'very clear emperor-has-no-clothes effect' that will lead to US President's downfall

A tell-all book on Donald Trump's first year in the White House will be the final nail in the coffin for his presidency, according to its author.

Michael Wolff said his revelations about the US President were filtering into the public consciousness and would result in his term coming to an end.

Allegations that the former real estate mogul acts like a "child" and has "less credibility than perhaps anybody who has ever walked on Earth at this point" have already made global headlines since excerpts emerged this week.

“I think one of the interesting effects of the book so far is a very clear emperor-has-no-clothes effect,” Mr Wolff told BBC Radio 4.

“The story that I have told seems to present this presidency in such a way that it says he can’t do his job."

He added: “Suddenly everywhere people are going ‘oh my God, it’s true, he has no clothes’. That’s the background to the perception and the understanding that will finally end ... this presidency.”

Mr Trump has repeatedly dismissed the book as "full of lies". It depicts a chaotic White House, a president who was ill-prepared to win office in 2016, and Trump aides who scorned his abilities.

The President renewed his attacks on Mr Wolff on Twitter on Friday, and on his former top aide Steve Bannon who was quoted in the book.

“Michael Wolff is a total loser who made up stories in order to sell this really boring and untruthful book,” he said. “He used Sloppy Steve Bannon, who cried when he got fired and begged for his job. Now Sloppy Steve has been dumped like a dog by almost everyone. Too bad!”

In his interview with the BBC, Mr Wolff was asked if he believed that Mr Bannon felt Mr Trump was unfit to serve as president and would try to bring him down. “Yes,” Wolff replied.

Mr Trump, up until Wednesday, had been complimentary of his former strategist, saying in October that the two “have a very good relationship” and had been friends for “a long time.”

In the book, Mr Bannon also speaks critically of Mr Trump’s daughter and White House adviser, Ivanka, calling her “dumb as a brick.”

“A little marketing savvy and has a look but as far as understanding actually how the world works and what politics is and what it means – nothing,” he is quoted saying.

Mr Wolff also hit back at claims that the book was untruthful in the interview.

“This is what’s called reporting. This is how you do it.” he said. “You ask people, you get as close as you can to the event, you interview the people who were privy to the event, you interview other people who were privy to the event, you come to know the circumstance as well as anybody and then you report it.”

He also suggested the leader was unaware what the term Brexit meant, two weeks before the UK's referendum on leaving European Union.
