Continuing the new series of European investigations in the Correspondent strand. As human-rights concerns push the issue of arms sales up the agenda, the Government continues to claim it has an ethical foreign policy. Yet the single biggest arms manufacturer is a British company. Novelist Will Self looks for the truth behind Britain's continuing involvement in the sale of weapons. Talking to manufacturers, industry spokesmen and attending an arms fair with MoD officials, Self assesses if Britain's defence exports are a source of credit or condemnation.
