Kweku Adoboli, the one-time UBS trader who had been accused of gambling away $2.3bn of the Swiss bank’s money, was poker-faced as he was sentenced to seven years in prison yesterday.

The 32-year old Adoboli had earlier in the day been found guilty of two charges of fraud for causing last year's $2.3bn unauthorised trading loss at the Swiss bank, which included concealing real trading positions with fictitious hedges. He was cleared of four lesser charges of false accounting.
