Sixty-eight-year-old David Greenhalgh and 48-year-old Christos Farmakis, from Surbiton, acted as middlemen for the black-market supply of ex-Soviet jets, surface to air missile systems, anti-tank missiles and thousands of assault riffles to be sent to countries including Sudan and Libya between 2009-2016.
Greek national Farmakis fled the UK while on bail and was sentenced in his absence.
