The Gaza Tribunal Report, a non-governmental and unofficial inquiry organized by civil society, was published on March 16, and concluded that the British government has been complicit – and in some cases an active participant – in genocide.
The inquiry also called for British government ministers and officials who are complicit to be investigated by the International Criminal Court (ICC).
It is the outcome of the Gaza Tribunal, held in Westminster on September 4-5 2025, chaired by former Labour MP Jeremy Corbyn and co-chaired by Dr. Shahd Hammouri, a lecturer in international law at the University of Kent and Neve Gordon, a professor of human rights law at Queen Mary University of London.
During the two-day Tribunal, which aimed to “uncover the full scale of Britain’s complicity in war crimes, crimes against humanity and genocide”, Corbyn and the co-chairs heard from “whistleblowers, experts, scholars and political figures to examine Britain’s complicity in Israeli war crimes in Gaza.”
The Tribunal also heard from witnesses who described in detail the human and social reality of displacement, ethnic cleansing, and genocide.
The new report outlines four key aspects of what has happened in Gaza: the destruction of the healthcare system, the destruction of the education system, the targeting of journalists, and the production of famine.
It suggests that Britain, as a member of the UN Security Council, a High Contracting Party to the Geneva Conventions, a party to the Genocide Convention and Rome Statute of the ICC, and due to its diplomatic, military, and economic ties with Israel, has numerous responsibilities with regards to Israel’s conduct in Palestine.
Britain’s failure in carrying out these responsibilities “has contributed to the mass killing of Palestinian civilians,” making it complicit and even an active participant in atrocity crimes.
As well as calling for investigation into individual government ministers and officials by the ICC, the report outlines seventeen recommendations for the UK government, including ending military co-operation with Israel, imposing economic sanctions, and joining the Hague Group.
It also calls for the government to “stop the criminalisation of anti-genocide protest and de-proscribe Palestine Action”, which remains illegal to support despite a High Court ruling that the proscription is “unlawful”.
During the launch of the report, Corbyn stated that he would present a copy of the report to the House of Commons library so that every MP would have access to it.
For Dr. Hammouri, the publishing of the report serves as a watershed moment, a call for collective action to uphold “the international legal system that has died in Gaza”, and work towards its “resurrection”.
