Campaign Against Antisemitism
Campaign Against Antisemitism is a British non-governmental organisation established in August 2014 by members of the Anglo-Jewish community. It conducts litigation, runs awareness-raising campaigns, organises rallies and petitions, provides education on antisemitism and publishes research. While the campaign describes itself as being "dedicated to exposing and countering antisemitism through education and zero-tolerance enforcement of the law"; critics have described the organisation as being "pro-Israel lobbyists".
History
CAA was set up in early August 2014, after an increase in antisemitic incidents that accompanied the 2014 Israel–Gaza conflict. A grassroots campaign, it grew largely out of social media activity among those who felt more should be done to promote the Jewish community's concerns after a meeting to discuss responses where a campaigner had her concerns dismissed by Board of Deputies of British Jews president Vivian Wineman. Its co-founder was Joseph Cohen.In January 2015, the then-UK Home Secretary, Theresa May, praised CAA for its work and undertook to ensure that the law against antisemitism is "robustly enforced". On 1 October 2015, it was registered as a charitable incorporated organisation. Its chief executive is Gideon Falter and its first director of communications was Jonathan Sacerdoti.
In November 2025, the Charity Commission issued CAA with a remedial action plan, in relation to an article about the British government's banning of the sale of certain weapons to Israel. In the commission's view, elements of the article did not further the CAA's stated objective of opposing antisemitism and the charity's inability to keep accurate records of the process by which the article was published amounted to "mismanagement". The CAA stated that it would legally challenge the decision.
Publications
CAA publishes primary and secondary research based on opinion polling and Freedom of Information Act 2000 requests. CAA's annual Barometer measures antisemitic sentiment in the UK and also surveys the effect of antisemitism on the Jewish community. Further, its National Antisemitic Crime Audit collects and analyses antisemitic crime data from all police forces in the United Kingdom. CAA uses the report to assess trends in antisemitic crime and to make recommendations to the British government. CAA also monitors antisemitism in political parties and the adoption of the IHRA definition by universities and local authorities in the UK.Rallies and petitions
CAA's first demonstration was in 2014 against the Tricycle Theatre in London, which had cancelled its hosting of that November's UK Jewish Film Festival due to the contemporaneous conflict in Gaza, unless the festival rejected funding from parties involved in the conflict, specifically a £1,400 sponsorship from the Israeli embassy, which the Tricycle Theatre offered to replace.Later that same summer, CAA led a demonstration outside the Royal Courts of Justice, attracting an estimated 5,000 people in the largest protest against antisemitism in a generation following a spike in antisemitic incidents. Attendees heard from Chief Rabbi Ephraim Mirvis, Maajid Nawaz, Douglas Murray, representatives from the Board of Deputies and others.
In August 2018, CAA organised a demonstration outside Labour Party's headquarters to protest against the handling of antisemitism in the Labour Party, and to condemn the-then party leader, Jeremy Corbyn. That same month, the organisation launched a Change.org petition titled "Jeremy Corbyn is an antisemite and must go"; it featured a Labour slogan modified to read "For the many not the Jew", which was signed by over 30,000 by 30 August 2018. A counter-petition against CAA with the title "To Get the Charity Commission to Deregister the Zionist Campaign Against Anti-Semitism" was signed by almost 7,500 and sent to the Charity Commission for England and Wales, which said in response that it was "assessing concerns raised about the Campaign Against Antisemitism's campaigning activities". In October 2018, the Charity Commission said that charities must be independent of party politics and insisted that CAA reword its petition.
In November 2018, CAA asked the Equality and Human Rights Commission to investigate the Labour Party. In May 2019, following complaints submitted by CAA, the EHRC launched a formal investigation into whether Labour had "unlawfully discriminated against, harassed or victimised people because they are Jewish". Following the referral to the EHRC by CAA, the Jewish Labour Movement and Labour Against Antisemitism Ltd also made submissions in support of the referral. The investigation ultimately found that the Labour Party had committed unlawful acts of discrimination against Jews under Jeremy Corbyn. Keir Starmer, leader of the Labour Party, responded to the findings when they were published in October 2020, saying at a press conference that it was a "day of shame" for the Labour Party.
In December 2019, CAA held a demonstration outside Parliament under its subsidiary brand Together Against Antisemitism. 3,200 attendees heard from speakers such as Tom Holland and Robert Rinder.
On 26 November 2023, following several pro-Palestinian marches in London during the Gaza war, the CAA organised the March Against Antisemitism, starting at the Royal Courts of Justice. The event was supported by mainstream Jewish organisations and figures, including the Chief Rabbi and the Jewish Leadership Council. Estimates from police indicate that between 50,000 and 100,000 people attended the march; it was claimed by the organisation to be "the largest gathering of its kind since the Battle of Cable Street". One month prior, CAA held a smaller demonstration outside the Scotland Yard Headquarters, to protest against what they deemed police inaction in the face of an uptick in antisemitic hate crimes.
Polling
CAA regularly conducts polling on both the Jewish community and wider British population. They produce an annual Antisemitism Barometer surveying both, which has regularly produced notable findings including, for instance, that 84% of British Jews considered Jeremy Corbyn to be a threat to the Jewish community in 2019. The 2019 survey is believed to be the first survey ever to suggest that antisemitism on the far-left had overtaken that on the far-right.Contributions to terrorist proscriptions
CAA were among those calling for organisations to be proscribed under the Terrorism Act 2000, including the neo-Nazi National Action and Islamist groups such as Hizb ut-Tahrir, which are both now proscribed. After the direct action group Palestine Action was implicated in the destruction of military equipment at RAF Brize Norton, CAA called for it to be proscribed and submitted a dossier on the group to Home Secretary Yvette Cooper. Palestine Action was proscribed on 5 July 2025.Litigation
CAA has used the process of judicial review in English law to scrutinise and reverse decisions made by the government and authorities. For example, in March 2017, CAA forced the Crown Prosecution Service to quash a decision not to prosecute an alleged far-right leader over a speech in which he issued a call to "free England from Jewish control". Whereas the CPS was sceptical that a crime had been committed, once the case reached a jury the defendant was found guilty and given a one-year custodial sentence.In 2021, Tahra Ahmed, a prominent Grenfell Tower volunteer aid worker, was reported by The Times to have claimed that the victims of the Grenfell Tower fire were "burnt alive in a Jewish sacrifice" and that the inferno profited Goldman Sachs. The CAA alleged that she was propagating antisemitic conspiracy theories to her thousands of Facebook followers, and reported her to the police. In January 2022 she was found guilty on two counts of publishing written material in order to stir up racial hatred, and was sentenced to eleven months in prison.
In early 2018, CAA began a private prosecution against Alison Chabloz, a Holocaust denier who released three YouTube videos of self-written antisemitic songs characterising Auschwitz as a "theme park" and the Holocaust as the "Holohoax". The case was taken over by the CPS and Chabloz was convicted. She was subsequently imprisoned for breaking the conditions of her suspended sentence.
In July 2018, Gilad Atzmon was forced to apologise to CAA chairman Gideon Falter and pay costs and damages after being sued for libel. Atzmon acknowledged that he had falsely stated that Falter had personally profited from fabricating antisemitic incidents.
In 2019, the CAA was sued by Tony Greenstein for libel in relation to CAA having published articles about him calling him a "notorious antisemite". In 2017, Greenstein had launched a petition asking the Charity Commission to deregister the organisation, claiming its purpose was to limit freedom of speech by calling opponents of Israel antisemitic. Greenstein's libel claim was dismissed.
In 2022, the Charity Commission confirmed that it had opened an investigation into the National Union of Students' charitable arm, following a letter calling on the regulator to do so from Robert Halfon, then the Chair of the Education Select Committee, and CAA. CAA also contributed to a separate investigation into NUS that found that the union had tolerated a "hostile environment" for Jewish students.
The CAA claimed in July 2025 that it was preparing a private prosecution against singer-songwriter Roger Waters under the Terrorism Act after he publicly declared his support for Palestine Action, which had been declared a terror organisation earlier that year.
In December 2025, attempted litigation against Reginald D. Hunter by CAA was quashed, with the presiding judge stating that the CAA had deliberately misled him and that the filing had been "abusive" with the CAA attempting to use the criminal justice system for "improper reasons".
