Jeffrey Epstein illegally supplied Peter Mandelson with drugs while he was a government minister, The Mail on Sunday can reveal.

Bombshell emails also expose how the paedophile financier arranged for the Labour peer to have cosmetic Botox injections while he visited him in New York.

The astonishing exchanges came while Epstein was under house arrest after his conviction for soliciting sex from a 14-year-old girl. And in the most shocking message, Mandelson tells the sex offender that drugs thought to be Xanax sedatives are ‘all very well but you need someone to use them on…’

Epstein is known to have got his victims – including Virginia Giuffre – hooked on Xanax to make them dependent upon him, and more pliant. It is a controlled drug in both the US and the UK, meaning it is illegal to possess it without prescription. The NHS does not prescribe it due to high risks of addiction.

Yet in one email Mandelson boldly asks Epstein where he will get more ‘triangles’.

Xanax pills come in different shapes depending on their dosage, with the most potent being green and triangular. Last night, Mandelson’s lawyers did not deny that the ‘triangles’ in the messages referred to Xanax.

The tranche of damning emails unearthed in the Epstein Files show that Mandelson was so close to the sex offender that he repeatedly asked for medical advice and medication.

They will heap further pressure on Sir Keir Starmer over his decision to appoint Mandelson as US ambassador, despite his known ties to the paedophile. Last week, it was revealed the Prime Minister was warned in writing that Mandelson continued his ‘particularly close’ friendship with Epstein for years after his sex offence convictions in 2008.

Last night, Shadow Home Secretary Chris Philp said: ‘These revelations are jaw-dropping. If Mandelson was being provided with restricted drugs and Botox from Epstein, it shows the depths to which he had become dependent on this evil paedophile. The police should immediately investigate.’

Epstein arranged for Mandelson to get Botox while he was on a taxpayer-funded visit to New York in March 2010. Even though Epstein was under house arrest at the time, Mandelson – who was then Business Secretary and Gordon Brown’s de facto Deputy Prime Minister – saw him twice. Ahead of the trip, Epstein asked Mandelson, ‘do you need me’ on March 3, to which the politician replied: ‘Always need you… have an official dinner on 3rd then fly back. What about the injections??’

In response, Epstein asked him whether Wednesday afternoon would work. The next day, Epstein asked ‘Wed face and neck?’ with Mandelson saying, ‘do you think I should’, to which Epstein replied: ‘Botox first step.’ They went on to arrange times, but it is unclear whether the procedure went ahead. The MoS did find an invoice for ‘Lipokit’, a brand of cosmetic fat transfer injection, dated the same day Mandelson visited Epstein – but this is different from Botox.

Mandelson made an apparent reference to Xanax in an email sent on December 5, 2009, asking ‘One triangle or two??’ and Epstein replied saying ‘one’.

Later that month, Epstein asked Mandelson, ‘feeling better?’, to which the politician replied: ‘How will I get more triangles?!’ And this was not the only drug Mandelson asked Epstein for.

On the day before his New York visit in 2010, he mentioned he was down to his last Niaspan pill – a prescription-only medication that lowers cholesterol and blood fat levels – and asked for more. Epstein confirmed he could get some, replying: ‘Already done with triangles’, to which Mandelson said: ‘yippie’.

In June 2010, Mandelson appears to have asked about getting more Niaspan before adding: ‘Triangles are all very well but you need someone to use them on…’ Niaspan is not known to be a recreational or cosmetic drug, but Epstein was evangelical about its benefits. He told Mandelson to take it ‘every day’ and also to ‘have your doctor give you a prescription… it will change your life’.

In March 2010, Epstein emailed Mandelson saying: ‘After the election, we should change your meds. it causes dry nose and baggy eyes… there are much newer more effective pills with less side-effects.’

Mandelson replied: ‘Haven’t got dry nose! Rash lasted for hour, face, hands and body. So if doing morning press conference had better take after.’

Mandelson also told Epstein he was taking the antidepressant, Dosulepin, after revealing he was having ‘major face rash’.

It is not clear where Mandelson obtained Dosulepin, as NHS guidance says it should not be prescribed for depression because it can be highly toxic and comes with significant cardiac risks.

But it is evident Mandelson trusted Epstein enough to seek his medical advice. As late as February 2011, the politician asked him when to take his medication when crossing time zones.

While it is known that Epstein’s victims were given drugs, today’s revelations are thought to be the first time they have been linked to his friends. It also appears that Epstein gave Mandelson clothes during his New York visit. Days after the trip, the Labour grandee emailed: ‘Wearing new jumper with new shoes and belt. Thanks!’

Mandelson’s lawyers last night refused to comment on any point raised in the MoS’s investigation.

The peer – who remains under investigation on suspicion of misconduct in public office – has previously expressed his regret over his links with Epstein and called their friendship a ‘most terrible mistake’ and ‘misplaced loyalty’.

‘I got a bonus for massaging Andrew and Mandelson…’ 

A former employee of paedophile Jeffrey Epstein has told how she was told to massage Andrew Mountbatten-Windsor and Peter Mandelson.

Christine Kenneally spoke out after an extraordinary picture emerged of Andrew and Mandelson, both wearing bathrobes, sitting with Epstein during the trip to Martha’s Vineyard, an island off Cape Cod in Massachusetts.

Ms Kenneally said she was flown to the island in 1999 by Epstein and his girlfriend Ghislaine Maxwell.

Describing Andrew and Mandelson as ‘perfect gentlemen’, she said nothing inappropriate happened. She was paid for the trip and given a bonus for the ‘important people’ she massaged.

Meanwhile, a leaked email shows how Andrew and his business associate Jonathan Rowland joked about ‘getting a massage’ amid the furore that followed an MoS interview in February 2011 with Virginia Giuffre, the Epstein trafficking victim and masseuse pictured with the former Prince.

Two months later, Mr Rowland told Andrew he was in China with a banker, saying they were ‘considering getting a massage… What do you think?’

Andrew replied: ‘Ha ha. F*** you too!’

The Crown Prosecution Service ‘failed’ when it declined to bring a case against Andrew Mountbatten-Windsor 10 years ago despite being given compelling evidence, the lawyer for his accuser has claimed.

David Boies, who represented Virginia Giuffre, said that the decision by the CPS and the Metropolitan Police in 2016 was ‘clearly erroneous’.

Mr Boies said that there was ‘substantial evidence’ that Andrew had sex with Ms Giuffre in London in 2001 when she was 17 after being taken there by the paedophile Jeffrey Epstein.

Instead the Metropolitan Police and the CPS said in 2016 they were not the right authorities as much of the conduct was not in Britain.

Now, after the release of three million files about Epstein by the US Department of Justice, the Metropolitan Police is one of 11 UK police forces investigating the operation of Epstein’s sex trafficking ring in Britain.

The claims by Mr Boies, one of the most prominent lawyers in the US, come days after Andrew was arrested for misconduct in a public office for allegedly passing sensitive information to Epstein.

The former Prince was questioned for 11 hours on his 66th birthday before being released from a police station in Aylsham, Norfolk.

He has not been charged with sex offences so far but Ms Giuffre, who committed suicide last April at the age of 41, claimed she was loaned to Andrew by Epstein three times in 2001.

Andrew has always denied her claims and said in his 2019 interview with BBC’s Newsnight he never met Ms Giuffre.

However in 2022 he settled a battery case she brought against him in a US court for a reported £10million.

In an exclusive interview, Mr Boies said that in 2016 he and his team spoke to American prosecutors after filing a defamation lawsuit in New York against Epstein’s ‘madam’ Ghislaine Maxwell.

According to Mr Boies, the US prosecutors relayed the claims against Andrew to their British counterparts but he ‘didn’t get any response’.

Instead, in November 2016, the Metropolitan Police and the Crown Prosecution Service issued a joint statement saying no further action could be taken because the allegations were largely focused on conduct outside the UK.

The Metropolitan Police said it was ‘not the appropriate authority’ and so would not be taking any further action.

Mr Boies called that decision not to investigate in 2016 ‘clearly erroneous’.

He said: ‘There was photographic evidence: the photograph of Andrew and Virginia in Maxwell’s (London) house, that was published in 2011.

‘The idea that they didn’t know it was happening in the UK is not sustainable.

‘Prosecutors generally have failed to pursue sex trafficking even when the evidence of it was presented and even when much of the evidence was public.’

Mr Boies said that even back in 2016 the evidence that Andrew had sex with trafficked women was compelling and there was ‘no significant room for doubt’ that Ms Giuffre was loaned to him by Epstein.

He said: ‘There’s substantial evidence based on Andrew’s presence at Epstein’s various residences, his interactions not just with Virginia but other victims as well that Andrew certainly should have known what was going on.’

Mr Boies praised King Charles and said that he had imposed ‘ever greater sanctions’ on his brother as the allegations against him grew more serious.

The blame did not lay with the Royal Family, as Mr Boies saw it, because Andrew was telling them the same lies he was telling the public.

Mr Boies said: ‘Everything I’ve heard…was Andrew was saying the same thing to his mother and brother and other people as he was saying publicly: ‘I didn’t do it, this is extortion, I’m innocent.”

Since Andrew’s arrest, his ex-wife Sarah Ferguson has not been seen publicly and Mr Boies said it was time for her to return to the UK and face the music.

But now she ‘absolutely’ had to go back to the UK and speak to the police because she was an ‘important’ witness, Mr Boies said.

He said: ‘The circumstances under which she gives her evidence I think can depend on what her exposure is but everybody (with evidence) ought to give it.’

Mr Boies worked with Ms Giuffre for several years through a series of bitter legal cases with Epstein, Maxwell and other powerful men.

The mother-of-three committed suicide last year at the age of 41.

Her not being alive to see Andrew arrested is ‘very, very sad’, Mr Boies said.

He said: ‘Had it not been for Virginia I would have never been involved. If it had not been for her we wouldn’t have had cases against Maxwell then Epstein that built an evidentiary record that helped with the prosecution in the US.

‘Had it not been for Virginia the focus would never have been on Andrew. She was the one that first outed him, she was the person who persisted year after year enduring enormous abuse and attacks from Epstein and his cohorts.

‘If it had not been for her the lawsuit against Andrew would never have been filed, and this thing could have easily died. She was a woman of enormous courage, commitment and I think not to have her alive when people are even partially being held to account is very sad’.  

As for Andrew, Mr Boies said that ‘if he doesn’t get it now, he never will’.

He said: ‘This might be enough of a shock to get him to understand he is not above the law.’

In its statement issued on Friday, the Metropolitan Police said that it was ‘assessing’ the Epstein Files released by the DOJ.

In addition, the force is ‘actively seeking further detail from law enforcement partners, including those in the United States’, the statement said.

The statement said: ‘While we are aware of the extensive media reporting and commentary about this matter, as of today, no new criminal allegations have been made to the Met regarding sexual offences said to have occurred within our jurisdiction. We continue to urge anyone with new or relevant information to come forward. All allegations will be taken seriously and, as with any matter, any information received will be assessed and investigated where appropriate.’

Ella Marriott, central specialist crime commander at the Metropolitan Police, added: ‘Our thoughts will always be with Ms Giuffre’s family and friends following her death.

‘In 2015, the Metropolitan Police Service (MPS) received allegations relating to non-recent trafficking for sexual exploitation involving Jeffrey Epstein and Ghislaine Maxwell. These allegations primarily concerned events outside the United Kingdom, with one allegation of trafficking to central London in March 2001.

‘Officers assessed all available evidence at the time, interviewed the complainant, Ms Virginia Giuffre as well as contacting several other potential victims. This did not result in any allegation of criminal conduct against any UK-based nationals. 

‘The MPS sought advice from the Crown Prosecution Service (CPS) and liaised with United States authorities, who were leading investigations into related matters involving US nationals.

‘Following this legal advice, it was clear that any investigation into human trafficking would be largely focused on activities outside the UK and perpetrators based overseas. 

‘Officers therefore concluded, in consultation with the CPS, that other international authorities were best placed to progress these allegations. 

‘Officers maintained close liaison with the United States and other relevant authorities throughout their investigation to ensure any UK matters could be identified and to consider any support requested.

‘A decision was made in November 2016 not to proceed to a full criminal investigation. That decision was reviewed in August 2019 and again in 2021 and 2022; in each instance, the position remained unchanged, and Ms Giuffre and her legal representative were informed.

‘Following recent reporting suggesting that Mr Andrew Mountbatten-Windsor asked his Met Police Close Protection Officer to carry out checks on Ms Giuffre in 2011, the MPS has carried out a further assessment. This assessment has not revealed any additional evidence of criminal acts or misconduct.

‘The Met remains committed to thoroughly assessing any new information that could assist in this matter. To date, we have not received any additional evidence that would support reopening the investigation. 

‘In the absence of any further information, we will be taking no further action. As with any other matter, should new and relevant information be brought to our attention, including in any information resulting from the release of material in the US, we will assess it.’

The Daily Mail has contacted the CPS for comment. Andrew and Sarah Ferguson have both been approached for comment.
