His activism has included Anti-Fascist Action, the Anti-Apartheid Movement, the Campaign for Nuclear Disarmament, and advocating for a united Ireland and Palestinian statehood.

[17][18][19] When Corbyn was seven, the family moved to Pave Lane, Shropshire, where his father bought Yew Tree Manor, a 17th-century farmhouse[20] which was once part of the Duke of Sutherland's Lilleshall estate.

[37] Corbyn was appointed a member of a district health authority and in early 1974, at the age of 24, he was elected to Haringey Council from South Hornsey ward.

[17][39] As a delegate from Hornsey to the Labour Party Conference in 1978, Corbyn successfully moved a motion calling for dentists to be employed by the National Health Service (NHS) rather than as private contractors.

[23] Michael Crick, in the 2016 edition of his book Militant, says that Corbyn was "a member of the editorial board",[47] as does Lansley, Goss and Wolmar's 1989 work The Rise and Fall of the Municipal Left.

[62][63] This was as a member of the City of London Anti-Apartheid Group (CLAAG) who carried out a "non-stop picket" for 1,408 days to campaign for Nelson Mandela's release from prison.

[71] Corbyn supported the campaign to overturn the convictions of Jawad Botmeh and Samar Alami for the 1994 bombing of the Israeli Embassy in London which argued that there was insufficient evidence to tie them to the act, along with Amnesty International, Unison and a number of journalists and other MPs.

[79][80][81][82][83] In 1986, Corbyn was arrested with 15 demonstrators protesting against what they saw as weak evidence and poor treatment during the trial of a group of IRA members including Patrick Magee, who was convicted of the Brighton hotel bombing and other attacks.

After refusing police requests to move from outside the court, Corbyn and the other protesters were arrested for obstruction and held for five hours before being released on bail, but were not charged.

[84] In 1987, Corbyn attended a commemoration by the Wolfe Tone Society in London for eight IRA members who were killed by Special Air Service soldiers while attacking a Royal Ulster Constabulary police station in Loughgall, County Armagh.

He was criticised for appearing on the channel in light of Iran executing and imprisoning homosexuals, as well as Corbyn not questioning contributors who called the BBC "Zionist liars" and described Israel as a "disease".

[108] Corbyn said in response that he used the programme to address "human rights issues" and that his appearance fee was "not an enormous amount" and was used to help meet constituency office costs.

[110] Corbyn was one of 16 signatories to an open letter to Ed Miliband in January 2015 calling for Labour to make a commitment to opposing further austerity, to take rail franchises back into public ownership, and to strengthen collective bargaining arrangements.

Corbyn decided to stand as a candidate, having been disillusioned by the lack of a left-wing voice, and said to his local newspaper, The Islington Tribune, that he would have a "clear anti-austerity platform".

[124] Jonathan Dean characterised Corbynmania as a political fandom, comparable with the enthusiastic followings of popular media stars and other modern politicians such as Bernie Sanders and Justin Trudeau.

Sung in the style of a football chant to the tune of a riff from "Seven Nation Army" by The White Stripes,[136] it attracted special attention at the Glastonbury Festival 2017, where Corbyn appeared and spoke to the crowds.

[143] Corbyn stressed his desire to reduce the "theatrical" nature of the House of Commons, and his début was described in a Guardian editorial as "a good start" and a "long overdue" change to the tone of PMQs.

[146] In July 2016, a study and analysis by academics from the London School of Economics of national newspaper articles about Corbyn in the first months of his leadership of Labour showed that 75% of them either distorted or failed to represent his actual views on subjects.

[149] Corbyn's election campaign was run under the slogan "For the Many, Not the Few"[150] and featured rallies with a large audience and connected with a grassroots following for the party, including appearing on stage in front of a crowd of 20,000 at the Wirral Live Festival in Prenton Park.

[153][154] This was partly attributed to the popularity of its 2017 Manifesto that promised to scrap tuition fees, address public sector pay, make housing more affordable, end austerity, nationalise the railways and provide school students with free lunches.

[161] During the campaign for the upcoming general elections, Corbyn was accused by the Hindu Council UK of promoting anti-Hindu sentiments[162] following his disparaging comments on the caste system[163] & his condemnation of the Hindu-right wing Bharatiya Janata Party led Indian government's revocation of the special status of Jammu and Kashmir.

In response, Corbyn established the Chakrabarti Inquiry, which concluded that while the party was not "overrun by anti-Semitism or other forms of racism", there was an "occasionally toxic atmosphere" and "clear evidence of ignorant attitudes".

[209] Writer Ronan Bennett, who formerly worked as a research assistant to Corbyn, has described him as "a kind of vegan, pacifist idealist, one with a clear understanding of politics and history, and a commitment to the underdog".

[216][217] In July 2016, academics from the London School of Economics published a study of 812 articles about Corbyn taken from eight national newspapers around the time of his Labour leadership election.

The study's director commented that "Our analysis shows that Corbyn was thoroughly delegitimised as a political actor from the moment he became a prominent candidate and even more so after he was elected as party leader".

[225] In an interview with Middle East Eye in June 2020, Corbyn described the media's treatment of himself while he was Labour leader as obsessive and "at one level laughable, but all designed to be undermining".

[239] In 2012, Corbyn went to Mexico to marry his Mexican partner Laura Álvarez,[240] who runs a fair trade coffee import business that has been the subject of some controversy.

They contacted fellow Labour MP Tony Benn for assistance, who introduced them to Corbyn, who met with the police on their behalf and spoke at fundraisers until the girl was located in 2003.

[259] On 19 January 2025, Corbyn, alongside former Shadow Chancellor of the Exchequer John McDonnell, agreed to be interviewed under caution by police following a pro-Palestinian rally in central London.

[266] In 2017 the American magazine Foreign Policy named Corbyn in its Top 100 Global Thinkers list for that year "for inspiring a new generation to re-engage in politics".
