Britain May Day Protest
Communist Party supporters hold a portrait of Soviet dictator Josef Stalin during a rally to mark May Day in central London, Sunday, May 1, 2011. Thousands of workers marched through the centre of the capital Sunday for a rally to mark May Day and a series of speakers denounced Government cuts and called for a fightback against them. Organisers put numbers for the event at 10,000, however the Metropolitan Police at Scotland Yard did not give a figure. (AP Photo/Lefteris Pitarakis)
