The practice acted for 112 institutional investors, as claimants, in seeking damages further to Tesco's admission that its earlier financial statements were overstated by at least £326m as a result of manipulation of its commercial income; the case is one of the first cases to be brought under new legislation that is designed to address serious corporate mis-statements in published statements.Clive Zietman heads the commercial litigation department and the 'ultra-responsive' Ian Gatt QC 'has a good understanding of clients' priorities'. Other highly rated advisers include Marc Jones, Fiona Gillett, Keith Thomas, Sean Upson, Paul Brehony and Andrew Hill. David Hughes was recruited from Dechert LLP, while Fiona Stewart left the firm.
