Tony Greenstein is a 72-year-old Jewish socialist activist, writer, and trade unionist with a decades-long track record of fighting for social justice and equality, and opposing racism, fascism, colonialism and imperialism.

Tony’s support for Palestine is inseparable from his Jewish identity. He is the son of an Orthodox rabbi who marched against Mosley’s British Union of Fascists in the 1930s. His support for Palestinian liberation emerged not in spite of his Jewish identity, but because of it: immersed from a young age in Holocaust history, Tony internalised its lessons as a mandate to oppose racism and injustice wherever they arise. He has been actively involved in groups such as the Jewish Network for Palestine and Jews for Boycotting Israeli Goods. In 2025, he was invited to speak at the First Jewish Anti-Zionist Congress in Vienna.

In his youth, he co-founded the Brighton and Hove Committee Against Fascism and Racism. In the 1980s, he sat on the executive of Anti-Fascist Action. He then co-founded the Palestine Solidarity Campaign, now the largest national Palestinian solidarity organisation of its kind in Europe.

Through decades of work with the Brighton Unemployed Workers Centre, and as a co-founder and trustee of the Brighton Trust charity, Tony has supported unemployed and homeless people, refugees, LGBTQ+ communities, and children growing up in poverty and war. Through sustained online fundraising, the Brighton Trust currently provides a vital lifeline for the Al-Tafawk Children’s Centre, which helps support Palestinian children from the Jenin refugee camp in the West Bank, one of the communities most violently impacted by Israeli occupation.

Tony is also a prolific political writer and independent blogger whose work spans more than 3,000 published blogs, with contributions to leading outlets including the Guardian, Al Jazeera, Open Democracy and Tribune. He is the author of the only book documenting the Fight against Fascism in Brighton and the South Coast, and of a major recent book on Zionism During the Holocaust.
