Al Jazeera’s Investigative Unit uncovers the true story behind the “crisis of anti-Semitism” that engulfed the British Labour Party under Jeremy Corbyn. It made him appear unfit to govern and led to a crushing electoral defeat. An analysis of internal party documents, social media data and covert recordings reveals how senior Labour officials used the party’s procedures to undermine support for Jeremy Corbyn and to silence debate about Israel’s treatment of Palestinians. The files also show how pro-Israel groups ask the party to distance itself from the Boycott Divest and Sanctions campaign, a protest movement that seeks to end Israel’s occupation of Palestinian lands, and how - in response - the Jewish Board of Deputies was assured that Labour would “never accept attempts to exceptionalise and deligitimise Israel.”

Al Jazeera’s I-Unit reveals how a British political party that claims to embrace progressive values created a hierarchy of racism that discriminated against its Black, Asian and Muslim members. Interviews, internal documents and social media messages shared by the most senior staff in Britain’s Labour Party betray a racist culture where abuse was aimed at their own colleagues, councillors and political leaders.

CORRECTION: An earlier version of this film reported that some WhatsApp messages about MP Diane Abbott suffering illness came after she announced that she had diabetes. In fact, some of the messages were written before her condition became publicly known.

In the final episode of The Labour Files – The Spying Game – Al Jazeera’s Investigative Unit tells the sinister story of how The Labour Party used hacked data from a journalist to investigate their own members who were critical of the party. Despite questionable ethical and legal issues, and with the knowledge of the party’s leadership, the hacked emails were used as evidence to discipline Labour councillors and activists in a London borough. The Spy Games lifts the lid on underhand tactics inside the Labour Party to impose order on party rivals using stolen confidential data.

Martin Forde, the independent barrister who produced a report on racism and factionalism in the British Labour Party, speaks publicly to Al Jazeera’s Investigative Unit about his report and The Labour Files. He reveals he has heard almost nothing from the Labour Party since the report was published. And he says he resisted pressure from the BBC to remove criticism of its 2019 Panorama documentary, Is Labour Anti-Semitic? Forde said he felt “vindicated” by the I-Unit investigation, The Labour Files, which he found fascinating.
