Former UBS trader Kweku Adoboli accused of unauthorised trading that cost the Swiss bank $2.3 billion (£1.5 billion) was due to enter a plea for the first time on Tuesday.
In a case that led to the resignation of UBS's chief executive, Adoboli 31, who worked as a director of exchange traded funds, has been charged with two counts of fraud and two of false accounting and will appear at Southwark Crown Court at 2:00 p.m.
UBS said it had uncovered rogue trades that took place between October 2008 and December 2010.
