Scotland Yard are reviewing the 24 hour operation to guard Julian Assange after the UK’s most senior officer admitted it is “sucking resources”.
Metropolitan Police Commissioner Sir Bernard Hogan-Howe told LBC radio the force is assessing its options after it was revealed the operation has reached the £10 million mark.
He said: "We won't talk about tactics but we are reviewing what options we have. It is sucking our resources."
The WikiLeaks founder has been avoiding extradition to Sweden by claiming asylum in the Ecuadorian Embassy in Knightsbridge since 2012.
Australian Mr Assange came under intense scrutiny after WikiLeaks began releasing a selection of more than 250,000 classified US diplomatic cables passed to the whistle-blowing website back in 2010.
Mr Assange's supporters last year pondered whether he was to end his self-imposed embassy stay amid concerns over his long-term health.
