The Financial Services Authority has charged four men – including a former banker at some of the biggest institutions in the City – with insider dealing as part of Operation Tabernula, a joint investigation between the regulator and the UK’s Serious Organised Crime Agency.

Martyn Dodgson, Benjamin Anderson, Iraj Parvizi and Andrew Hind have all been charged with conspiracy to insider deal between November 1, 2006 and March 23, 2010, and have been bailed to attend Westminster Magistrates' Court on October 19, 2012.
