Sarah Ferguson visited Jeffrey Epstein twice at the office of a bogus firm he had set up while he was still serving time in jail for a child sex offence. 

Emails buried deep in the Epstein Files reveal the former Duchess of York travelled to Palm Beach in Florida once in April 2009 and again in May that year. 

The meetings took place at the office of Epstein's fake company, the Florida Science Foundation, which he invented to secure work release while in prison. 

Fergie appears to have discussed how she could make money at one of the visits - and even planned to return on a third occasion but those plans fell through at the last minute.  

It has also been revealed that Lord Peter Mandelson phoned and video-called Epstein at the office while he was staying at the financier's New York mansion. 

Epstein victims have alleged he abused them inside Florida Science Foundation's headquarters while he was supposed to be in jail at the nearby Palm Beach County Stockade. 

The sex offender was involved in a generous work release programme following his conviction for procuring a minor for prostitution in June 2008, which allowed him to leave jail for up to 12 hours a day, six days a week to work from his office. 

He was supervised by off-duty Sheriff's deputies.

But despite the fact he was still serving jail time, Ms Ferguson asked the paedophile whether she could see him during a stopover in Palm Beach.

On April 4, 2009, she sent him an email saying: 'Hello Jeffrey. I am landing in Palm Beach in a couple of hours. Is there any chance on my quick layover that I can get to have a quick cup of tea...'

Ferguson signed off the email: 'Love Sarah The red Head.!!' 

Epstein responded, telling her she could visit him and gave her the address of his office in West Palm Beach which he said was 'ten minutes from the airport'.

Following the meeting, which appears to have mainly been about her business Mothers Army, Epstein emailed her saying 'you look great' and telling her 'I read everything you gave me, too many pictures... not enough substance i.e. numbers'.

He gave her advice on how to get a £10million sponsorship deal and instructed her to get women like Michele Obama involved in the business.

She replied to thank him for his advice, saying: 'My dear spectacular and special friend Jeffrey. 

'You are a legend, and I am so proud of you... for being such a great friend.'

More emails from that period also suggest she tried to visit him again later in April, which ultimately did not happen.

Then, in May, when he was still in prison, she emailed him: 'I am coming into Palm Beach to see you on Wednesday I land at 9.30am. 

'Can your brilliant [driver] pick me up, bring me to you, The Great one!! And then take me to Miami!??? Please with roses on top!'

Epstein told his staff to 'please coordinate' her request.

Later emails also suggest that Ms Ferguson walked past a Sheriff's deputy to get into Epstein's office in the April visit as the paedophile needed to be monitored when on day release from prison.

During the same week as one of Ferguson's visits, Lord Mandelson called Epstein at his Palm Beach office from London, The Telegraph has reported. 

The then-business secretary told Epstein things were 'still riotous here politically' amid the fallout from the MPs' expenses scandal in 2009. 

The following month, Lord Mandelson video-called Epstein at the Florida Science Foundation's office while he was staying at the paedophile's townhouse in New York.

This was four weeks before Epstein was formally released from jail. 

Lord Mandelson, who has been stripped of his titles over his links to the paedophile, has maintained he never saw any evidence of wrongdoing during his time spent with Epstein. 

A spokesman for Ms Ferguson previously told the BBC: 'The Duchess spoke of her regret about her association with Epstein many years ago, and as they have always been, her first thoughts are with his victims.

'Like many people, she was taken in by his lies. As soon as she was aware of the extent of the allegations against him, she not only cut off contact but condemned him publicly, to the extent that he then threatened to sue her for defamation for associating him with paedophilia.'

The Daily Mail has approached Lord Mandelson's representatives for comment.
