Britain's Prince Andrew stepped down from public duties on Wednesday, saying the controversy surrounding his "ill-judged" association with late US financier Jeffrey Epstein had caused major disruption to the royal family's work.

Andrew, Queen Elizabeth's second son, denies an allegation that he had sex with a 17-year-old girl procured for him by his friend Epstein, who killed himself in a US prison in August while awaiting trial on sex trafficking charges.

The scandal has escalated since Andrew did an interview with BBC TV, aired on Saturday. The interview has drawn widespread criticism in the media, where many have said his explanations were unsatisfactory, while lawyers for Epstein's victims said the prince showed little sympathy for those abused.

As the story dominated news headlines for a fourth day and a slew of businesses distanced themselves from organisations and charities associated with the prince, he said he would step down from public life for the time being and speak to police about Epstein.

"It has become clear to me over the last few days that the circumstances relating to my former association with Jeffrey Epstein has become a major disruption to my family's work," he said in a statement issued by Buckingham Palace.

"Therefore, I have asked Her Majesty if I may step back from public duties for the foreseeable future, and she has given her permission," said Andrew, 59, whose official title is the Duke of York.

"Of course, I am willing to help any appropriate law enforcement agency with their investigations, if required."

Andrew's conduct has overshadowed much of the political campaigning for Britain's parliamentary election on Dec. 12.

In a televised debate on Tuesday night, Prime Minister Boris Johnson said the monarchy was "beyond reproach" while opposition Labour Party leader Jeremy Corbyn said the institution "needs a bit of improvement" and that there were questions to be answered.

The favourite

Andrew, widely reputed to be the favourite of the queen's three sons, has been under scrutiny over his friendship with Epstein for several years.

Now eighth-in-line to the throne, he quit as Britain's roving trade ambassador in 2011 after being lambasted for his links to the financier following Epstein's jailing in 2008 for child sex offences.

Then in 2015, one of Epstein's accusers, Virginia Giuffre, said she was forced to have sex with Andrew in London, New York and on a private Caribbean island between 1999 and 2002, when she says Epstein kept her as a "sex slave".

In his BBC interview, Andrew categorically denied the sex claims and gave a series of explanations as to why her account was not true.

He said her account of meeting him sweating and dancing almost two decades ago at a London nightclub before having sex with him could not be true, noting that he suffered from a medical condition that stopped him perspiring.

He also said that on the night he was alleged to have met her he was at home with his family after visiting a Pizza Express restaurant in the commuter town of Woking with his daughter Beatrice.

The explanations provoked derision and ridicule in newspapers and social media.

He also told the BBC he had met Epstein in 1999 but his private secretary had written to the Times newspaper in 2011 saying they were introduced in the early 1990s.

Rather than drawing a line under the accusations, the interview has led to more questions and businesses pulling out of supporting his charities and Pitch@Palace scheme to help young tech entrepreneurs.

BT, one of Britain's oldest companies and its largest broadband provider, told a scheme that helps develop digital skills to drop Andrew as its patron if it wanted to maintain BT's support.

"I continue to unequivocally regret my ill-judged association with Jeffrey Epstein," Andrew said in his latest statement.

"His suicide has left many unanswered questions, particularly for his victims, and I deeply sympathise with everyone who has been affected and wants some form of closure."

From helicopter pilot to 'airmiles Andy'

As a young man, Andrew was one of the most popular royals, acclaimed by the British press for his active service as a helicopter pilot during the 1982 Falklands War and earning the nickname "Randy Andy" for his courting of glamorous girlfriends.

He turned heads when he dated US actress Koo Stark, who had appeared in a soft-porn film.

But, the once second-in-line to the throne dropped in the public's affection and as he slipped down the line of succession, he was dubbed "Airmiles Andy" over accusations of a lavish jetset playboy lifestyle, funded by the taxpayer.

His 1986 marriage to flame-haired Sarah Ferguson, which was hailed as a breath of fresh air to the monarchy, ended in divorce a decade later but she remains one of his strongest supporters.

"Andrew is a true+real gentleman and is stoically steadfast to not only his duty but also his kindness + goodness," she wrote on Twitter on Friday.

Royal commentators say Andrew has always been fiercely protective of his royal status, insisting that his daughters Eugenie and Beatrice were princesses, a contrast to the children of his elder sister Anne who have no title.

Eugenie's wedding last October took place at Windsor Castle, drawing media criticism over the estimated 2 million pound ($2.6 million) security bill borne by taxpayers.

Queen Elizabeth, who was celebrating her 72nd wedding anniversary with husband Prince Philip on Wednesday, appeared at a reception to present the naturalist David Attenborough with an award but made no comment about Andrew.

Dickie Arbiter, the monarch's former press secretary, said Andrew's decision was inevitable.

"He really had no choice, he'd gone into that interview on the belief probably it was crisis management, but he created more of a crisis than managing it," Arbiter told Sky News.

"I'm sorry to say he's arrogant enough to believe his own myth that he could get away with it, and he didn't get away with it. I think the queen is very frustrated. At 93, she doesn't need this."
