You could almost hear the rejoicing in Whitehall on Friday morning when the High Court cleared the way for Julian Assange to be extradited to the US, rejecting a plea that he was too mentally frail. The man has, after all, been a thorn in the administration’s side for 11 years: 18 months contesting his rendition to Sweden, followed by seven embarrassing years holed up in the Ecuadorian embassy, and then two-and-a-half years in Belmarsh fighting extradition to the US on espionage charges.
