30 July 2013 Last updated at 18:56 BST

Bradley Manning, the US Army private accused of leaking thousands of classified documents, has been found guilty of 20 espionage-related charges - but not guilty of the most serious charge of aiding the enemy.

Pte Manning, 25, had acknowledged leaking the documents to anti-secrecy organisation Wikileaks but said he did so to spark a debate on US foreign policy.

The leak is considered the largest ever of secret US government files and Pte Manning faces a maximum sentence of more than 100 years. His sentencing hearing is set to begin on Wednesday.

The BBC's Gordon Corera explains, in 90 seconds, the background to the case.
