The east side of the square, lying opposite one of the main entrances to the Palace of Westminster, has historically been a common site of protest against government action or inaction.
Reclaim the Streets On
May Day 2000 the square was transformed into a giant
allotment by a
Reclaim the Streets guerrilla gardening action.
Parliament Square Peace Campaign Brian Haw staged a continual protest there for several years, campaigning against
British and American action in
Iraq. Starting on 2 June 2001, Haw left his post only once, on 10 May 2004 – and then because he had been arrested on the charge of failing to leave the area during a security alert – and returned the following day when he was released. The alleged disruption caused by Haw's protest led Parliament to insert a clause into the
Serious Organised Crime and Police Act 2005 (SOCPA) making it illegal to protest in Parliament Square (or, indeed, in a large area reaching roughly half a mile in all directions) without first obtaining the permission of the
Metropolitan Police Commissioner. As well as sparking a great deal of protest from various groups on the grounds of infringement of
civil liberties including the
European Convention on Human Rights, the Serious Organised Crime and Police Act 2005 was initially unsuccessful in accomplishing its goals: Brian Haw was held to be exempt from needing authorisation in a High Court ruling, as his protest had started before the act came into effect (though any new protests would be covered); Haw remained in Parliament Square. Later, the Court of Appeal overturned this ruling, forcing Haw to apply for police authorisation to continue his protest. The provisions of that act relating to Parliament Square were repealed by the
Police Reform and Social Responsibility Act 2011, which provides for a different regime of "prohibited activities". The
Parliament Square Peace Campaign was a
peace campaign started by
Brian Haw in 2001 and carried on by
Barbara Tucker until 2013.
Democracy Village In May 2010, a peace camp known as Democracy Village was set up on the square to protest (initially) against the British government's involvement in invasions in the
Middle East, which became an eclectic movement encompassing left-wing causes and anti-globalisation protests. The
Mayor of London Boris Johnson appealed to the courts to have them removed and, after demonstrators lost an appeal in July 2010,
Lord Neuberger ruled that the protesters camping on the square should be evicted. The final tents were removed in January 2012.
Palestine Action On 9 August 2025, a large demonstration in support of
Palestine Action was held at Parliament Square. When
Big Ben chimed 1 p.m. during the protest, large numbers of demonstrators revealed signs which read "I oppose genocide. I support Palestine Action", leading to the arrest of 532 people—the largest made by the
Metropolitan Police on a single day in the previous 10 years. ==Statues==
