Anthony Keith Parnes is an English millionaire who was involved with Ernest Saunders, Gerald Ronson, and Jack Lyons in the Guinness share-trading fraud of the 1980s; they collectively became known as "the Guinness Four".
The son of a London gown manufacturer, Parnes started his working life as an office boy with a stockbroker. Parnes started at the bottom, working in the Stock Exchange as a 'blue button' at A. J. Bekhor. He established a reputation for dealing with the big players of the fringe banking world. Because of his success his colleagues nicknamed him "The Animal".
Parnes built up the strategic shareholding in Debenhams for Ronson and Sir Philip Harris during Burton's fiercely contested bid for the department store group. That stake helped win the bid for Sir Ralph Halpern, Burton's chairman, in a cliffhanging finish. The vote went in favour of Burton after the bid had been extended from the 3pm Friday deadline to the following Sunday in a special dispensation by the Takeover Panel. Parnes was a big dealer who acted for some of the biggest names in the share dealing business. After working at stockbrokers A.J. Bekhor, Rowe Rudd and McNally, he became a "half commission" man (that is, an introducing broker) with Alexander Laing and Cruickshank. As well as having dealt for various clients, Parnes' relations include the former chief executive of the major British jewellery company Ratners Group Gerald Ratner and the restaurateur and club-owner Richard Caring. Anthony Parnes' son, Michael Parnes, also became a stock broker. Michael Parnes was chief executive of natural resource focused brokerage Old Park Lane Capital.
Parnes and others had supported the Guinness share price to enable it to merge favourably with Distillers. Described as "flamboyant" by The Scotsman, he was sentenced to two-and-a-half years on charges of false accounting and theft, but had his sentence reduced to 21 months on appeal.
Parnes’ case was that a reasonable man with experience in the City would not at the time have regarded what he did as dishonest. Guinness shares did not reach a price higher than was justified. He did not accept he had any responsibility to make disclosure to the Stock Exchange. The payments he received were for lawful and valuable services. He was not told that the arrangements he made for Guinness plc had not been sanctioned by its board of directors.
