The Met police tweeted that they have removed the officers who have stood guard outside the embassy since Assange sought refuge in June 2012, citinga “strengthened overt plan at [the] Ecuadorian embassy”.
Assange was arrested on a European Arrest Warrant in December 2010, and ordered to face criminal charges for rape in Sweden, but he skipped bail and has been in the embassy since.
As of June, the bill for guarding Assange 24/7 was £11.1m.
The Met said in a statement it had discussed the decision with the Home and Foreign Offices and had to balance the interests of justice with the safety of Londoners and “investigating crime and arresting offenders wanted for serious offences”.
It said it “remains committed to executing the arrest warrant and presenting Julian Assange before the court, [but] it is only right that the policing operation to achieve this is continually reviewed against the diplomatic and legal efforts to resolve the situation... And there is no imminent prospect of a resolution to this issue.
“The operation to arrest Julian Assange does, however, continue and should he leave the Embassy the MPS will make every effort to arrest him. However, it is no longer proportionate to commit officers to a permanent presence.”
