Three former Barclays bankers have been formally charged with conspiring to make false Libor submissions to benefit of the bank at a court in central London.

Jonathan Mathew, 31, Peter Johnson, 58, and Stylianos Contogoulas, 42, all former employees of Barclays, appeared at Westminster Magistrates court on Wednesday and spoke only to confirm their names.

The Serious Fraud Office (SFO) is alleging that Mr Mathew, Mr Johnson, and Mr Contogoulas were involved in a conspiracy to knowingly submit false or misleading US dollar Libor rates between June 1, 2005 and August 31, 2007.
