British lawmakers are calling for an independent investigation into how the country's financial regulator treats whistleblowers, following the death of a former City trader who exposed undisclosed business ties between US Commerce Secretary Howard Lutnick and the late sex offender Jeffrey Epstein.
Simon Andriesz, who had worked as a senior employee at the international brokerage BGC Partners, died in Thailand last month. His family confirmed he took his own life on 23 September and said there was no indication of foul play. The death has intensified scrutiny of the Financial Conduct Authority (FCA) and its treatment of individuals who come forward with allegations of misconduct.
Earlier this year, Andriesz approached the FCA, the FBI and other regulatory bodies with evidence he had uncovered suggesting business links between Epstein and Lutnick. According to the source material, that evidence cast doubt on Lutnick's public statements regarding his associations with the disgraced financier, who died in 2019 while awaiting trial on sex-trafficking charges.
The centrepiece of Andriesz's disclosures was evidence that Lutnick had sought to "buy a prince"—in Andriesz's own words—by offering to enter into a business partnership with Andrew Mountbatten-Windsor in 2013. The proposal involved leveraging the former prince's contacts to attract investment in exchange for a £1m loan. BGC has told the BBC that the proposed joint venture never went ahead.
Andriesz also submitted evidence to the FCA supporting allegations of misconduct at Lutnick's former firm. Among the claims was an assertion that cash from a commission pool set aside to pay brokers' bonuses had been "embezzled" for improper purposes. The firm has denied that allegation.
A group of UK MPs has now said the circumstances surrounding Andriesz's death raise "deeply troubling questions" about how whistleblowers are treated when they approach the FCA with concerns about wrongdoing, and about the retaliation they may subsequently face. The lawmakers are pressing for the regulator to fund an independent party to evaluate its handling of whistleblower cases.
John McDonnell, the Labour backbench MP who chairs the All-Party Parliamentary Group on Investment Fraud and Fairer Financial Services, described Andriesz's death as a "profound and preventable tragedy." He argued that whistleblowers serve as "an essential part of the financial regulatory system," and cautioned that the integrity of that system would suffer if people stopped believing they would be "treated properly, protected appropriately and listened to seriously."
Weeks before his death, Andriesz spoke at a public event organised by MPs, whistleblowers and campaigners who are pushing for fairer regulation. He told the gathering he felt "thoroughly let down" and said the FCA had put him through "absolute hell." He had sent the regulator evidence of what he regarded as whistleblower retaliation by BGC and its lawyers.
The FCA had previously informed Andriesz that there was "insufficient evidence" to conclude that retaliation had occurred. He believed that conclusion damaged his prospects of winning a claim against BGC at an employment tribunal.
In July, Andriesz told MPs and campaigners that the FCA had been fully aware of other serious allegations he had raised as far back as 2018, and he accused the regulator of failing to act. The FCA told the BBC at the time that it had acted on his allegations and pointed to a supervision order it had issued on the basis of the information he provided.
Andriesz, however, regarded that measure as little more than a regulatory "slap on the wrist." In his view, it made it harder for him to pursue a whistleblower retaliation claim against BGC at tribunal. Later that same month, he told a meeting of the Transparency Task Force that the FCA was not meeting its obligations to the public and to whistleblowers, accusing it of merely paying "lip service" to rules and regulations.
"It protects the institution and then exposes the whistleblower to extreme retaliation and devastation to their lives and families," he said at the time.
BGC has previously told the BBC that it maintains strong policies designed to protect whistleblowers and has denied retaliating against Andriesz.
The FCA has said it is appointing a new non-executive director to its board—Lea Paterson, a former Bank of England director—to conduct a review into Andriesz's treatment and the regulator's handling of his whistleblower allegations. An FCA spokesperson said: "We are very sorry to hear of Mr Andriesz's death. Our thoughts are with his family and friends."
The case has drawn attention to the broader question of how regulators balance institutional interests against the protection of individuals who report wrongdoing. Advocates for whistleblowers argue that when regulators conclude there is insufficient evidence of retaliation, the effect can be to leave those who speak up isolated and exposed to further pressure. The MPs' call for external scrutiny reflects concern that the FCA's own review, even if conducted by a new board member, may not be sufficiently independent to restore public confidence.
The disclosures made by Andriesz also carry significant political weight on both sides of the Atlantic. Lutnick, who founded and ran BGC Partners before being appointed to his role by US President Donald Trump, has faced questions about the accuracy of his public accounts of his relationship with Epstein. The evidence gathered by Andriesz—including the 2012 photograph discovered in the Epstein files showing Lutnick and Epstein together on Little St James, the financier's private island—has fuelled those questions.
For the FCA, the episode represents a critical test of its credibility as a regulator that depends on insiders coming forward with information. If whistleblowers conclude that the cost of speaking up outweighs any protection they receive, the flow of intelligence on which enforcement action relies could diminish. The outcome of the review into Andriesz's treatment, and whether it satisfies demands for genuine independence, is likely to shape that debate for some time to come.
