A new witness has come forward to corroborate claims that Prince Andrew was dancing with his alleged accuser at Tramp nightclub, The Mail on Sunday can reveal.

Virginia Roberts says convicted paedophile Jeffrey Epstein forced her to have sex with the Prince after a night of dancing at the trendy London club in March 2001.

After watching the Prince deny Ms Roberts's claims during his 'car-crash' interview with Emily Maitlis on BBC's Newsnight, a woman came forward to insist she had seen him at Tramp that evening.

Accuser: Virginia Roberts claims Epstein forced her to have sex with Prince Andrew after dancing with him in March 2001

Lisa Bloom, a Los Angeles-based lawyer who represents five of shamed US financier Epstein's victims, last week flew to London to interview her – and appeared on ITV breakfast show This Morning.

Now, The Mail on Sunday can reveal that during the trip Ms Bloom tracked down a second person – a friend of the woman she originally came to interview – who supports her account of the night in question.

During last month's interview at Buckingham Palace, the Prince said he was not at Tramp and had taken his eldest daughter Beatrice to a party at Pizza Express in Woking that afternoon before returning home.

But Ms Bloom last night told The Mail on Sunday: 'The first woman, a Londoner, contacted me after she saw Prince Andrew's interview.

'She was very disappointed that he denied knowing Virginia and denied being at the nightclub. That's what spurred her to come forward. No-one should be above the law.'

Ms Bloom said the first witness was with a friend who has corroborated her story and also saw the Prince dancing with Ms Roberts.

She declined to go in to details, saying only she was preparing to take the two witnesses to America to speak to the FBI.

She added: 'The FBI is looking in to Prince Andrew. They want to speak to him. He's said he wants to cooperate with law enforcement and yet it doesn't seem to be happening, so I would like to help this move forward.

'The woman was in Tramp with a friend who said, 'Look, there's Prince Andrew.'

'She looked at him [Andrew] and was very struck by him because she'd never been in a room with a Royal before, and she never has been since. She stared at him.

'He was with a young woman who she now knows was Virginia Roberts.

'She remembers that Prince Andrew was smiling and seemed to be happy and Virginia was not. Virginia not smiling made an impression too.'

Ms Bloom added: 'I don't want to go in to too much detail at this stage but both of them are credible witnesses.

'We are at the stage where we are investigating and corroborating and then we will take them [the witnesses] to the FBI. The problem Prince Andrew has is that people meet him, or even see him, and it's very memorable for them.

'It's not memorable for him because he meets people every day but people remember meeting a member of the Royal Family.'

Ms Roberts, who now goes by her married name of Giuffre, claims she was 17 when she was 'trafficked' to Prince Andrew by Epstein and the financier's then girlfriend, British socialite Ghislaine Maxwell.

Backlash: The prince has been forced to withdraw from public life due to his connection with Epstein

In a BBC Panorama interview broadcast last week, the now 35-year-old mother of three told how the Prince was 'pouring with sweat' on the dance floor and said she felt 'horrified and ashamed' when she was forced to have sex with him when they returned to Ms Maxwell's Belgravia mews house.

'He knows what happened. I know what happened. And there's only one of us telling the truth. And I know that's me,' she added.

Prince Andrew says her claim that he was 'raining with sweat' on the dance floor cannot be true because he did not perspire at the time due to a medical condition brought on by a surge of adrenaline after being shot at during the Falklands War.

Asked if either of the two new witnesses saw the Prince sweating, Ms Bloom said: 'I'm not going in to specific details at this time as our investigation is ongoing.'

Buckingham Palace has repeatedly and categorically denied Ms Roberts's claims, which they describe as 'demonstrably false and untrue'.

However, a backlash that followed the Newsnight interview forced Prince Andrew to step back from his public duties. Epstein killed himself in jail in August as he faced multiple child sex charges.

More than 80 women have now come forward to claim he sexually assaulted them.
