A City trader who lost £1.4bn of Swiss bank UBS's money has been found guilty of two counts of fraud.

Kweku Adoboli denied four charges of false accounting and two of fraud between October 2008 and September 2011.

The prosecution told Southwark Crown Court he was "a gamble or two away from destroying Switzerland's largest bank".

Adoboli said he was encouraged to take risks by his bosses. He was cleared of four charges of false accounting.

The BBC's Emma Simpson examines how he actually came to lose so much money.
