An exclusive interview with one of Britain's leading investigative journalists and a former insider, the Trail of the Dove reveals the extent of surcharges, commissions and the $100 millon secret fund used by the UK's leading arms firm, BAE Systems, to grease the wheels of the biggest arms deals in British history. Al-Yamamah 'The Dove' is the name of a series of massive arms sales by the United Kingdom to Saudi Arabia. It is Britain's largest ever export agreement, and the prime contractor has been BAE Systems and its predecessor British Aerospace, which earned £43 billion in 20 years.
