Millionaire businessman James McCormick, 56, has been convicted at the Old Bailey of three counts of fraud after selling fake bomb detectors.

The Advanced Detection Equipment was based on a golf ball finder device and sold for up to $40,000 (£27,000) in Iraq, Georgia, Saudi Arabia and Niger.

McCormick, of Langport, Somerset, marketed the detectors to military, governments and police and the UN, making an estimated £50m.
