WikiLeaks founder Julian Assange has been jailed for 50 weeks at Southwark Crown Court for a bail breach offence.

The Australian 47-year-old appeared for sentencing at Southwark Crown Court on Wednesday morning.

He was found guilty of breaching the Bail Act at a hearing at Westminster Magistrates' Court earlier this month after being arrested at the Ecuadorian Embassy.

Assange was accused of sexual offences in Sweden in 2010, and after exhausting his legal options against an extradition order, went to the Ecuadorian Embassy on June 19 2012.

A warrant for his arrest was issued 10 days later.

At the hearing on April 11 District Judge Michael Snow remanded Assange in custody and branded him a "narcissist who cannot get beyond his own selfish interests".

The judge said: "This is a case which merits the maximum sentence, which is 12 months in the Crown Court."
