WikiLeaks editor Kristinn Hrafnsson has said that the UK “should never underestimate the ability of Julian Assange to enter into a fight and get the best of his opponents”.
Mr Assange, the founder of WikiLeaks, has been found guilty of breaching his bail and faces a jail sentence of up to 12 months when he is sentenced at Crown Court.
Mr Assange was further arrested on behalf of US authorities having been removed from the Ecuadorian embassy by the Metropolitan Police on Thursday morning.
Mr Hrafnsson told talkRADIO’s George Galloway that with Mr Assange’s arrest “the fight has just begun”.
He said: “Julian Assange is an extraordinary character. The battle is now beginning because now we have everything out of the shadows.
“We know exactly what we are dealing with. The fight has just begun.
“It is going to be fierce and it is going to be fought on every front. You should never underestimate the ability of Julian Assange to enter into a fight and get the best of his opponent.”
The WikiLeaks editor said he had “no doubt in his mind” that the organisation had done the right thing by publishing the confidential documents.
He added: “We have a duty towards the general public to publish information from sources who are whistleblowers.”
