A new trove of confidential documents lays bare the extent to which Anglo-South African group Investec was involved in suspect deals worth hundreds of millions of Euros that resulted in European governments being defrauded through the infamous “cum-ex” withholding tax scam. In doing so, Fin24 reports, the elite bank joins the ranks of lawyers, bankers and financial service outfits from across the world already implicated in what is widely reported to be the largest fraud in history, allegedly costing European revenue services more than EUR55 billion, mostly between 2007 and 2012. Evidence contained in the leak also raises the possibility that senior staff, some of whom still occupy top positions at Investec, may have approved the bank’s involvement in these schemes – laying themselves and the bank open to potential criminal and civil liability.
