Vogue editor Anna Wintour has dismissed claims that she once asked Donald Trump to become the UK ambassador, as 'laughably preposterous'.

Michael Wolff's explosive new book Fire and Fury claims that the fashion industry icon had visited Trump Tower and 'suggested that she become Trump's ambassador to the Court of St. James'.'

The position is the official title for the US ambassador to the UK - one of the most prestigious and highly sought after diplomatic roles.

'Trump was inclined to entertain the idea,' the book continued, although former White House Chief Strategist Steve Bannon was against it, reportedly saying it was 'fortunate' that 'there was no chemistry.'

But a representative for Wintour, a long-time Democrat who campaigned for Barack Obama and Hillary Clinton, told Business Insider the claims were nonsense.

'I think it's pretty clear where Anna stands politically, which makes this laughably preposterous,' they said.

This is not the first time there has been rumors about British-born Wintour vying for the UK ambassador role. After she campaigned hard for Barack Obama in 2008, doing a considerable fundraising effort, it was reported she was expecting the role.

But she was disappointed to discover the job had instead gone to Matthew Barzun, a former technology executive who spent 20 months as finance chairman of Barack's fundraising operation. She reportedly threw her hat back into the ring again in 2012 but was unsuccessful.

At the time, Trump was supportive, tweeting in December 2012. 'I am happy to hear that Pres. Obama is considering giving Anna Wintour an ambassadorship. She is a winner and really smart!'

Trump was initially supportive, tweeting in December 2012. 'I am happy to hear that Pres. Obama is considering giving Anna Wintour an ambassadorship. She is a winner and really smart!'

When it became clear she wouldn't become ambassador under Obama, Wolff wrote that she 'closely aligned herself with Hillary Clinton.'

Wintour was an outspoken Clinton support and backed her presidential campaign in 2016, appearing with her at numerous different fashion and charitable events.

The editor-in-chief wore a Clinton 2016 T-shirt in February to Marc Jacobs' New York Fashion Week show, and donned it again in October that year during a fundraiser for the presidential hopeful.

But when Clinton lost out to Trump in election, Wintour lost her chance at the ambassadorship to the UK.

That's when Wolff claims Wintour 'arrived at Trump Tower (but refused to do the perp walk) and suggested that she become Trump's ambassador to the Court of St. James'.'

Trump later referred to Wintour's ambition in a mocking tweet in December 2016, after Vanity Fair's Hive posted a video showing its editors suggesting New Year's resolutions for Clinton that would stop her from running again'

Trump, who seems to have confused Wintour, the editor of Vogue, as being the editor of Vanity Far, tweeted: 'Vanity Fair, which looks like it is on its last legs, is bending over backwards in apologizing for the minor hit they took at Crooked H.

'Anna Wintour, who was all set to be Amb to Court of St James's & a big fundraiser for CH, is beside herself in grief & begging for forgiveness!'

However, it does seem unlikely that Wintour, a sworn Democrat, would jump ship for Trump - particularly when she has made her disdain for the Republican clear in the past.

During an appearance on James Corden's Late Late Show last October, she named Trump as the only Met Gala guest she would never invite back.

While Wintour didn't explicit say on the show why she would rather not see President Trump among the A-list event crowd, she has clearly opposed his politics.

Wintour, the eldest daughter of former London Evening Standard editor Charles Wintour, began her career in journalism in the UK, before she moved to the US for a stints at New York and House & Garden magazines.

She returned to London to become the editor of British Vogue, from 1985 and 1987. The following year she flew to New York to take over the helm as US editor of Vogue and Condé Nast artistic director, where she has remained since.

But she retains close ties to the UK, and just last year she was named Dame Commander of the Order of the British Empire or DBE, for her services in the fashion and journalism industries.

Meanwhile, Wolff's explosive new book has sparked major controversy since highlights have begun to emerge this week.

Trump said Breitbart chair Bannon had 'lost his mind' after he was quoted insulting the president's children, including claims he called Ivanka Trump 'dumb as a brick.'

But many have denied some of the outrageous claims, such as former British Prime Minister Tony Blair who dismissed allegations he told Trump's campaign team that UK intelligence services were spying on him in the run up to the election.
