Bank of England flags up 50 potential cases of market rigging

Mark Carney says 42 cases have been sent to FCA following forex-rigging scandal and new Bank policies for staff to raise suspicions

Bank of England governor Mark Carney has said 50 cases of potential market abuse have been uncovered following the foreign exchange-rigging scandal that led to the Bank's own chief currency dealer being fired last year.

The cases have come to light since March 2014 when the Bank launched an investigation into its own role in the scandal involving the manipulation of the 3.5tn-a-day foreign exchange markets.
