The Serious Fraud Office has upped the stakes in the case of the controversial $3 billion Qatari financing that saved Barclays from a taxpayer bailout in 2008, by extending the charge of ‘unlawful financial assistance’ to the operating company, Barclays Bank plc, as well as the parent, Barclays plc. Four senior former Barclays employees, including the then chief executive John Varley, are already due to stand trial early next year on the same and other fraud-related charges.
