Kweku Adoboli, the former UBS trader accused of causing the largest unauthorised trading loss in UK history, could have been a potential future leader at the bank but was at risk of getting “burnt out”, a jury heard today.

Charles Sherrard QC, Adoboli's defence barrister, told Southwark Crown Court today that Adoboli had been a member of UBS's Ascent programme, an initiative that brings together potential future leaders at the bank.
