You don't accidentally broker deals for surface-to-air missiles and Soviet fighter jets. It takes calculation, a web of front companies, and a blatant disregard for international law. David Greenhalgh and Christos Farmakis learned this the hard way at Southwark Crown Court, where they each received 16-year prison sentences for running an elaborate, multi-million-pound illicit weapons network between 2009 and 2016.
If you've been following how international arms trafficking works in the modern era, this case shatters any illusions that illegal weapons trade relies purely on shadowy figures operating out of cargo ships at midnight. Instead, it relies on white-collar professionals wearing suits, exploiting advisory boards, and forging paperwork while sipping coffee in corporate offices.

The Anatomy of a Global Black Market Ring
The scale of the operation revealed by Her Majesty's Revenue and Customs (HMRC) investigation is staggering. Greenhalgh, a 68-year-old businessman from Croydon, used his Airservices group of companies—strategically registered across the UK, Greece, North Macedonia, and South Sudan—to move lethal hardware. His partner, 48-year-old Greek national Christos Farmakis, served as an adviser to Greater London Enterprise (GLE), a government-funded quango.
They didn't deal in small arms alone. While thousands of assault rifles formed part of the inventory, the pair brokered trades involving: Similar coverage regarding this has been provided by NPR.
- Former Soviet aircraft and fighter jets
- Surface-to-air missile systems
- Anti-tank missile networks
- Heavy weaponry destined for volatile conflict zones like Sudan, South Sudan, and Libya
Judge Sally-Ann Hales KC didn't mince words during sentencing. She noted that their crimes were "deliberate, sophisticated, financially motivated and persisted over many years."
How They Evaded Detection for Years
How do you sell fighter jets to embargoed nations without triggering red flags? The answer is forged end-user documentation and calculated bribery.
According to prosecutors, Greenhalgh and Farmakis routinely fabricated end-user certificates. They made it look like military hardware was heading to legitimate, un-sanctioned nations, while the cargo actually went straight into active war zones. Corrupt payments to public officials lubricated the wheels of this illicit supply chain.
Farmakis used his position within GLE as a respectable corporate shield. He even brandished credentials from UK Trade & Investment to project an aura of absolute legitimacy to buyers and suppliers alike. Meanwhile, Greenhalgh brushed off direct warnings. Back in January 2012, HMRC explicitly briefed Greenhalgh that his British nationality meant he was bound by UK trade controls regardless of where he operated in the world. He ignored the warning, dubbed his illegal shipments "sensitive projects," and kept routing transactions through overseas subsidiaries to dodge detection.
The Crackdown and Accountability
The operation finally collapsed under the weight of an intensive nine-week trial that ended in convictions at Southwark Crown Court. When the legal net tightened, Farmakis chose to flee. He was granted bail during proceedings, skipped the country, and was tried and convicted in absentia. He is believed to be hiding in Greece, while Greenhalgh faced the dock alone to hear his 16-year sentence.
Defense teams pointed to Greenhalgh's age and lack of previous convictions, attempting to frame him as a wheeler-and-dealer who dabbled in everything from second-year clothing exports to sugar refineries and theme parks. The court, however, drew a hard line. International trade controls exist for a distinct reason: to stop high-grade military equipment from fueling devastating conflicts across the globe.
