JD Wetherspoon chairman Tim Martin has turned his sights on one of London's most successful property entrepreneurs in his fight against what he describes as "greedy" property agents. The pub chain, which Mr Martin set up, filed a writ at the High Court against property entrepreneur Antony Lyons, over his alleged part in the "fraudulent and dishonest" sale of pubs to Wetherspoon by the company's then adviser Van de Berg. In 2009 Wetherspoon successfully sued property agent Van de Berg and its founder, Christian Braun, for fraudulently and dishonestly advising on property transactions over a number of years.
