The lawsuit brought by JB Drax Honoré against Darren Williams centered on his March 2025 resignation from the London derivatives broker, a roughly £400,000 loan the firm wanted repaid, and six-month post-termination restrictions it sought to enforce. The High Court granted an interim injunction in July 2025 keeping Williams out of a competitor, and the parties settled on undisclosed terms on 31 October 2025, before the scheduled November trial.1ICLR.

What the Dispute Was About
Williams, a sales broker at the firm, resigned on 12 March 2025. He claimed a fundamental breakdown of trust and confidence and alleged constructive dismissal. JB Drax rejected that account and treated the departure as a standard resignation on notice, placing his termination date at 12 September 2025 and his six-month non-compete running until 12 March 2026.1ICLR.

The money at the heart of the case was a loan JB Drax made to Williams in November 2024, valued by Law360 at roughly £400,000 (about $542,000). The loan would have been forgiven had Williams stayed for three more years. Once he resigned, the firm demanded repayment. Williams countered that the loan was tied to what he called an unfair demotion and that his bonuses had been reduced to claw the amount back. JB Drax also argued Williams’ access to sensitive client information exposed the firm to unfair competition if he moved to a rival.3Law360.

The July 2025 Injunction Ruling
On 21 July 2025, Her Honour Judge De Bertodano, sitting as a High Court judge in the King’s Bench Division, heard JB Drax’s application for interim relief. She found a “serious issue to be tried” on both the constructive dismissal claim and the enforceability of the restrictive covenants, citing TFS Ltd v Gamberoni & Ors [2017] IRLR 698 for the proposition that six-month post-termination restrictions are not unusual in derivatives brokerage.1ICLR.

The balance of convenience went to JB Drax. If Williams won at trial, the judge reasoned, his losses from being kept out of work could be measured and paid. If the injunction were refused and JB Drax was right, the damage from a competitor gaining his expertise and client relationships would be much harder to quantify. The court barred Williams from working for or providing services to any competitor pending a full trial set for early November 2025.1ICLR. JB Drax Honore v Darren Williams [2025] EWHC 2233 (KB)

Where Williams Went Next
By December 2025, Williams had joined Marex, another London broker, as global head of relative value trading. He was the second senior trader sued by JB Drax to end up at Marex. As of May 2026, Marex listed him as heading its relative value execution desk. Available reporting does not indicate that JB Drax sued Marex directly over either hire.5FN London.
