Thousands of people took to the streets of London for anti-capitalist demonstrations.

The protests began with a procession of cyclists from Liverpool Street to King's Cross, bringing morning rush-hour traffic to a standstill on some of the capital's busiest routes.

More than 6,000 police officers were employed to control later protests at Oxford Circus.
