Jeremy Bernard Corbyn (/ˈkɔːrbɪn/; born 26 May 1949) is a British politician who has been Member of Parliament (MP) for Islington North since 1983. He currently sits as an independent, and is the interim leader of Your Party, which he co-founded with Zarah Sultana in July 2025. Corbyn had previously been a member of the Labour Party from 1965 until his expulsion in 2024, and served as Leader of the Opposition and Leader of the Labour Party from 2015 to 2020 and was a member of the Socialist Campaign Group parliamentary caucus. He identifies ideologically as a socialist on the political left.
Born in Chippenham, Wiltshire, Corbyn joined the Labour Party as a teenager. Moving to London, he became a trade union representative. In 1974, he was elected to Haringey Council and became Secretary of Hornsey Constituency Labour Party until elected as the MP for Islington North in 1983. 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. As a backbencher, Corbyn routinely voted against the Labour whip, including New Labour governments. A vocal opponent of the Iraq War, he chaired the Stop the War Coalition from 2011 to 2015, and received the Gandhi International Peace Award and Seán MacBride Peace Prize. Following Ed Miliband's resignation after the party had lost the 2015 general election, Corbyn won the 2015 party leadership election to succeed him. The Labour Party's membership increased sharply, both during the leadership campaign and following his election.
