John Edward Palmer (September 1950 – 24 June 2015) was an English gangster, former market trader and gold dealer, involved in various criminal activities including mortgage and timeshare fraud. The police believed that much of his alleged £300 million fortune was the result of swindles, violence, racketeering and money laundering. Palmer owned a complex network of 122 companies, many offshore in the Isle of Man, Madeira and the British Virgin Islands, as well as 60 offshore bank accounts.
