The death of a British former financial industry whistleblower in Thailand last month has sparked urgent calls from UK members of parliament for a full independent investigation into the treatment of whistleblowers by the country’s top financial regulator, the Financial Conduct Authority (FCA).
Simon Andriesz, a one-time senior employee at BGC Partners — the global brokerage firm founded and led by current U.S. Commerce Secretary Howard Lutnick before his appointment to the Trump administration — died by suicide on September 23 in Thailand, according to his family, who confirmed there is no evidence of foul play.
Earlier this year, Andriesz brought forward undiscovered evidence to the FCA, the FBI, and multiple other regulatory bodies that exposed unreported business ties between Lutnick and disgraced late sex offender Jeffrey Epstein, directly contradicting Lutnick’s previous public statements about the nature and extent of his relationship with Epstein. A 2012 photograph from the Epstein files, unearthed during Andriesz’ probe, shows Lutnick alongside Epstein on Little St James, the private island linked to Epstein’s criminal activities.
Among the other explosive allegations Andriesz brought forward was a 2013 proposal that Lutnick made to Prince Andrew, the Duke of York, to enter a joint business venture. In Andriesz’ account, Lutnick offered a £1 million loan to Prince Andrew in exchange for access to the former royal’s network to attract new investments. BGC Partners has confirmed the proposal was never finalized. Andriesz also accused senior leadership at BGC of embezzling funds from a broker commission pool reserved for employee bonuses for inappropriate uses — a claim the firm has repeatedly denied.
In the final weeks before his death, Andriesz spoke openly at a public event for campaigners and MPs pushing for stronger financial regulation, saying he felt completely failed by the FCA and described his experience interacting with the regulator as “absolute hell”. He claimed that after he submitted evidence of retaliation against him by BGC and its legal team, the FCA ruled there was insufficient evidence to support his retaliation claim — a decision that made it far more difficult for him to pursue a legal claim against BGC in employment tribunal.
The FCA has previously countered that it did act on Andriesz’ allegations, pointing to a public supervision order it issued against BGC that drew directly from his submitted evidence. But Andriesz dismissed this action as little more than a trivial “slap on the wrist”, and argued the regulator’s weak response undermined his private legal action. He went further in remarks to the Transparency Task Force campaign group, accusing the FCA of only paying lip service to whistleblower protection rules, saying: “It protects the institution and then exposes the whistleblower to extreme retaliation and devastation to their lives and families.”
BGC has consistently denied all wrongdoing, saying it maintains strict policies to protect whistleblowers and never retaliated against Andriesz.
Now, cross-party UK MPs are throwing their weight behind a full probe, calling Andriesz’ death a “profound and preventable tragedy”. John McDonnell, Labour backbench MP and chair of the All-Party Parliamentary Group on Investment Fraud and Fairer Financial Services, emphasized that whistleblowers are a critical pillar of the global financial regulatory system. He warned that if potential whistleblowers do not trust that regulators will treat them properly, protect them from retaliation, and take their claims seriously, the integrity of the entire UK financial system will suffer lasting damage.
The group of MPs is calling for the FCA to fund an fully independent review of its entire framework for handling whistleblower claims. In response to the growing pressure, the FCA announced it has appointed Lea Paterson, a new non-executive board member and former Bank of England director, to lead a review into its handling of Andriesz’s specific case and identify lessons for future whistleblower interactions. In an official statement, an FCA spokesperson said: “We are very sorry to hear of Mr Andriesz’s death. Our thoughts are with his family and friends. Since expressing our condolences, we’ve asked Lea Paterson, who has just joined our board as a non-executive director, to review how we interacted with Mr Andriesz to learn any lessons for the future.”
