Metropolitan Police officers had been in place since Mr Assange sought asylum to avoid extradition to Sweden over a rape allegation, which he denies.
Julian Assange, the founder of the international whistleblowing website WikiLeaks, will no longer have overt 24-7 police surveillance at London's Ecuador embassy.
It's been revealed guarding the 44 year-old Australian in central London has cost British taxpayers more than 20-million (AU) dollars.
Swedish prosecutors say they want to question Mr Assange about a rape claim, which carries a 10-year statute of limitations that expires in 2020.
Mr Assange, who sought sanctuary in 2012, denies the allegation and insists the sexual encounter was consensual.
He fears Sweden will extradite him to the United States where he could be put on trial over WikiLeaks' publication of classified military and diplomatic documents in 2010, one of the largest information leaks in US history.
Mr Assange's Swedish lawyer, Per Samuelson, says guarding the embassy has been a waste of British taxpayers' money.
"If he leaves the embassy, he stands the risk to be extradited to the United States. They can't afford to do that. So he will stay in the embassy and he's happy, of course, that there are no guards around the clock any more. But he congratulates the UK citizens because it's been a waste of money and I think that the UK can use the money otherwise."
A statement from the Metropolitan Police Service says its emphasis will shift to a covert plan to arrest Julian Assange if he leaves the embassy.
London-based human rights lawyer Geoffrey Robertson, who in the past has represented Julian Assange, has told Sky News the WikiLeaks founder has had no intention to escape.
"It was absurd to have that police presence because Mr Assange wasn't going anywhere. He didn't want to flee the embassy because he would be arrested and he would be subject to an extradition request from America."
Earlier this year, Julian Assange told Radio New Zealand British news coverage suggesting he was trying to avoid actual charges in Sweden are misleading.
He said he sought refuge in the embassy for fear of facing extradition to the US.
"My political asylum in this embassy relates to a very large pending prosecution in the United States for espionage; it's not in relation to Sweden. The UK also has additional cases as well, in relation to Sweden. There's no charges. There's a 'preliminary investigation' and that matter, I have already been cleared in, already found to have committed no crime."
He also stated his belief he'd been abandoned by the Australian government.
"Australia is famous for abandoning Australian citizens generally who are involved in any kind of political conflict, it's not just me, they've done it to a number of others. It's only when there's extreme outrage developed in relation to say, death penalties in Indonesia. But they make sure it's done too late or occasionally in relation to a state like Egypt, but those are smaller states. They're not the United States."
In August, Swedish officials said they hope to reach a judicial cooperation deal with Ecuador by year's end that would pave the way for prosecutors to question Mr Assange.
Britain has made a formal protest to Ecuador over Julian Assange through its ambassador in Quito.
