Julian Assange loses court battle to stop US expanding extradition appeal

Judges say psychiatric expert report can form part of Washington's full appeal

The WikiLeaks founder, Julian Assange, has lost a high court battle to prevent the US government expanding the grounds for its appeal against an earlier refusal to allow his extradition to face charges of espionage and hacking government computers.

On Wednesday, judges said the weight given to a misleading report from Assange's psychiatric expert that was submitted at the original hearing in January could form part of Washington's full appeal in October.
