Paul "The Plumber" Davidson
Paul "The Plumber" Davidson (born 21 June 1955) is a British businessman and entrepreneur. He became widely known in the UK business press following proceedings brought by the Financial Services Authority (FSA) concerning a spread bet related to the 2002 flotation of biotechnology company Cyprotex. In 2006, the Financial Services and Markets Tribunal determined the references in favour of Davidson and trader Ashley Tatham.
A former pipe-fitter, from which his nickname derives, Davidson was fined £750,000 by the Financial Services Authority for market abuse in 2004, a fine which was subsequently overturned.
