More than 30 people have been arrested after anti-capitalist protesters clashed with police in Central London.
There were scuffles after officers surrounded a building in Soho - where a group called "Stop G8" were holding a "Carnival Against Capitalism".
Further demonstrations took place nearby, ahead of the two-day summit of world leaders in Northern Ireland next week.
