[1] Activist Brian Haw launched the campaign at the site on 2 June 2001, initially as an around-the-clock protest in response to the United Nations economic sanctions imposed on Iraq.
[2] His protest grew broader following the war in Afghanistan and 2003 invasion of Iraq.
[3] He was joined by Barbara Tucker in December 2005, and stayed at the site day and night for nearly a decade.
Tucker carried on the campaign following Haw's death in June 2011.
The London Evening Standard reported in January 2013 that Tucker had started a hunger strike after protesting in the square for a total of eight years.
