Tens of thousands of people marched through central London on Saturday in what organisers described as the largest anti-far-right demonstration in British history. The Together Alliance, supported by around 500 groups including trade unions, antiracism organisations and Muslim representative bodies, led the rally that converged on Whitehall near the Houses of Parliament. Organisers claimed half a million participants, while police estimated about 50,000. The event was met by a much smaller group of counterprotesters waving Israeli and pre-1979 Iranian flags.

Speakers and participants said the march aimed to counter the rise of racism and Islamophobia in mainstream politics, citing figures such as Reform leader Nigel Farage and far-right activist Tommy Robinson. Demonstrators described the atmosphere as inclusive and festive, comparing it to the Notting Hill Carnival. Several left-wing politicians, including Jeremy Corbyn, Zarah Sultana, Dianne Abbott, and Andy Burnham, joined the crowds, while Amnesty UK praised the event as a call for dignity, compassion and human rights.

The protest took place amid warnings from the group Hope Not Hate that the British far right is becoming “bigger, bolder and more extreme than ever before.”
