Assange has been in custody at Belmarsh prison in south-east London since April 2019,following his expulsion from the Ecuadorian embassy,where he lived as a fugitive for seven years to avoid extradition to Sweden on sexual assault charges.
The decision means Assange’s legal team will be able to challenge US assurances over how his prospective trial would be conducted and whether his right to free speech would be infringed.
Dame Victoria Sharp,the president of the King’s Bench Division of the High Court,and Justice Johnson granted leave to appeal on those points. A date has not yet been set for the appeal hearing.
Assange was not in court because of his deteriorating mental and physical health,but among his supporters present were his wife,Stella,and his father,John Shipton.
Speaking to thousands of supporters gathered outside the court after the hearing,Stella Assange said Biden had the opportunity to drop the 13-year-legal pursuit of her husband before the presidential election in November.
“We are relieved as a family that the courts took the right decision today,but how long can this go on for? Our eldest son just turned seven,” she said.
