Jeremy Corbyn: British politician and former Labour leader

Overview

Jeremy Bernard Corbyn (born 26 May 1949) is a British politician who served as Leader of the Labour Party and Leader of the Opposition from 2015 to 2020 and has been the Member of Parliament for Islington North since 1983. Often self-described as a democratic socialist, Corbyn rose to national prominence after a grass-roots campaign won him the party leadership in 2015. His tenure reshaped debates within British politics on public spending, foreign policy and the role of organised labour, while also provoking intense public scrutiny and internal party disputes.

Background and early career

Corbyn was born in Chippenham in Wiltshire and was active in local politics from a young age. Before entering Parliament he worked as a trade union representative and in community advocacy, serving on Haringey Council in the 1970s. He later became secretary of the Islington Constituency Labour Party and won the parliamentary seat of Islington North in 1983. Throughout his career as an MP he maintained a profile as a campaigner on human rights, international development and local welfare issues, which earned him recognition from a range of civil society organisations.

Political positions and priorities

Corbyn’s politics emphasise greater public investment and opposition to austerity measures introduced after 2010, with calls to protect public services and social security. He has supported measures to tackle tax avoidance by large corporations and wealthy individuals, and advocated for renationalisation or increased public ownership in sectors such as rail and utilities as a means of ensuring affordable services. On foreign policy, Corbyn has been associated with anti-war activism, opposition to military intervention, and membership in groups campaigning for nuclear disarmament. Those positions reflect a broader platform that prioritises diplomacy, human rights, and multilateral approaches over the use of force.

Labour leadership, elections and parliamentary record

Corbyn entered the Labour leadership contest in 2015 following Ed Miliband’s resignation. Unexpectedly strong support from trade unions and new party members helped secure him the leadership in September 2015. His leadership faced immediate internal challenges: after the 2016 referendum on EU membership, a large number of Labour MPs expressed no confidence in his leadership and many members of his shadow cabinet resigned, precipitating a second leadership election in which he was re-elected with an increased mandate. Under his leadership, Labour performed better than many expected in the 2017 general election, gaining seats and producing a hung parliament, but the party suffered a significant defeat in 2019. Corbyn announced he would not lead Labour into the next general election and was succeeded by Sir Keir Starmer in April 2020.

Controversies and assessments

Corbyn’s leadership provoked strong reactions both inside and outside the Labour Party. Supporters praised his emphasis on inequality, public services and grassroots participation, crediting him with energising many new voters and reinvigorating left-of-centre politics. Critics argued that his leadership was marred by organisational weaknesses and that his stance on certain foreign policy issues and his handling of allegations of antisemitism within the party damaged Labour’s public standing. These concerns culminated in investigations and disciplinary actions; Corbyn was suspended from the party in October 2020 after commenting on the findings of an external inquiry, a suspension that affected his parliamentary party status even after his membership was later restored. Commentators continue to debate his long-term influence on the Labour movement and on British politics more broadly.

Legacy, influence and distinctions

Corbyn’s period as Labour leader marked a clear pivot in proposals and rhetoric for parts of the party, with renewed emphasis on public ownership, redistribution, and participatory politics. He remains a divisive figure: to some he represents a principled and consistent activist-politician who broadened debate about economic inequality and foreign policy; to others he is associated with a period of electoral decline and internal turmoil. After stepping down as leader, he continued to sit in Parliament and to engage in political campaigns and public debates on domestic and international issues.
