About 300,000 people participated in the march, demanding a ceasefire in the Israel-Gaza conflict, making it the UK's largest rally since the conflict began.
The protests led to 126 arrests, primarily of counter-protesters, including far-right groups, to prevent breaches of the peace. Clashes were reported at London's Cenotaph and Chinatown. Sunak emphasized that all criminal actions must be met with the law's full force.
The Metropolitan Police faced confrontations and aggression from some counter-protesters. Despite the tension, a two-minute silence at the Cenotaph for Armistice Day was observed respectfully.
The pro-Palestinian march, organized by the Palestine Solidarity Campaign, extended about 2.5 miles with chants of "free Palestine" and calls for a ceasefire.
Labour leader Sir Keir Starmer and London Mayor Sadiq Khan have criticized the Home Secretary's handling of the situation, with calls for her resignation. The Met praised their officers' efforts in managing the protests and ensuring the safety of sites like the Cenotaph, and reported on hate crime arrests related to the protests.
