Wikileaks founder Julian Assange has won the right to ask the Supreme Court to block his extradition to the US.
The High Court ruled on Monday he could have raised a legal point that Supreme Court justices may want to consider.
The ruling means Mr Assange can petition the UK’s highest court for a hearing, stalling any extradition from the UK for now.
He is wanted in the US over the publication of thousands of classified documents in 2010 and 2011.
In December, the US won an appeal against a previous UK court ruling that he could not be extradited due to concerns over his mental health.
The Wikileaks documents revealed how the US military had killed hundreds of civilians in unreported incidents during the war in Afghanistan, while leaked Iraq war files showed the 66,000 civilians had been killed and prisoners tortured by Iraqi forces.
The US says the leaks broke the law and endangered lives, but Mr Assange says the case is politically motivated.
