Police and bailiffs on Tuesday moved to dismantle the anti-capitalist camp which sprang up outside London's St Paul's Cathedral in October last year, according to the City's local authority.
"Today the City of London Corporation has begun to enforce the high court orders for the removal of the tents and equipment outside St Paul's," the corporation said in a statement.
"We regret that it has come to this but the high court judgment speaks for itself and the Court of Appeal has confirmed that judgment.
Occupy London Stock Exchange, which has been camped outside the landmark since October 15 after taking inspiration from protesters in New York's Wall Street, confirmed the arrival of bailiffs.
"Police arrive at St Paul's," OccupyLSX said on its Twitter webpage. "Look to be kettling (barricading) the tents".
