A rogue trader who carried out the UK's largest ever fraud, losing £1.4 billion in bad deals which nearly brought down a major international bank, has been jailed for seven years.
At one point during his run of losses, former rising star City trader Kweku Adoboli, 32, stood to run up losses of 12 billion US dollars (£7.5 billion) for employer UBS.
City of London Police, which investigated his activities after he confessed his losses in an email to colleagues, said he was one of the most sophisticated fraudsters the force had come across.
Adoboli was accused of exceeding his multi million-pound trading limits and failing to hedge trades, faking records to cover his tracks at the Swiss bank's London office.
He admitted the losses but claimed that he was pressured by staff to take risks, culminating in bad deals which wiped £2.8 billion off the bank's share value when they were discovered.
The Ghanaian-born former public schoolboy was sentenced after a trial that lasted more than nine weeks at Southwark Crown Court in London.
The jury convicted him unanimously of one count of fraud linked to the £1.4 billion loss.
He was found guilty of a second fraud charge by majority verdict but cleared of four remaining charges of false accounting after the jury deliberated for 16-and-a-half hours across five days.
Jailing him, trial judge Mr Justice Keith told Adoboli: "There is a strong streak of the gambler in you. You were arrogant to think the bank's rules for traders did not apply to you."
