LONDON

A report led by former Labour leader Jeremy Corbyn recommended that UK ministers face investigation by the International Criminal Court (ICC) over alleged “complicity” and “participation in genocide” in Gaza.

The report aimed to “uncover the full scale of British complicity in genocide.”

The Tribunal heard testimony from witnesses including journalists, medics, academics, survivors, international law experts, lawyers, and whistleblowers.

The report concluded that the British government has “failed in its fundamental obligation to prevent genocide,” has been complicit in atrocity crimes, and in some instances actively participated in them.

It calls on the ICC to investigate UK officials involved in maintaining economic ties, arms sales, and intelligence sharing with Israel.

Corbyn said the Tribunal aimed to serve as “a landmark contribution to the campaign for justice and as a historical repository of evidence for generations to come.”

He highlighted Britain’s strategic role, noting: “Britain is not the biggest arms contributor to Israel… but Britain is a crucial part of it, because of the RAF base in Akrotiri, because of the sharing of intelligence information and because of the way the US has significant military presence in Britain.”

"This whole process has eroded Britain's standing in the world, eroded Britain's commitment to international law, to the UN to human rights, to international justice through the ICJ and the ICC," he added.

Co-author Shahd Hammouri warned that humanity has crossed a “red line of genocide,” accusing top UK officials of lying, manipulating the law, and protecting “the interests of foreign governments and big businesses, not the British public.”

She warned that unchecked complicity could fuel further conflicts in Gaza, the West Bank, Lebanon, and Iran.

Professor Neve Gordon said the UK government’s actions set a “very dangerous precedent” and called for ministerial accountability to prevent repetition of atrocities. “Accountability is the most effective guard against the repetition of such crimes in the future,” Gordon said, noting that British military bases continue to support operations targeting civilians abroad.
