The prosecution in the trial of Kweku Adoboli told a London court today – as it began delivering its closing statement – that "the finger of blame" for last year's $2.3bn trading loss at UBS "pointed directly" to the former trader.

Sasha Wass QC this morning began her closing speech on behalf of the prosecution in the criminal case against Adoboli, who faces two counts of fraud and four of false accounting. Adoboli has pleaded not guilty to all of the charges in the case, which began in September at London's Southwark Crown Court and is in its 36th day.
