Jeremy Bernard Corbyn is a British politician serving as Leader of the Labour Party and Leader of the Opposition since 2015. He has been the Member of Parliament (MP) for Islington North since 1983. Ideologically, Corbyn identifies as a democratic socialist. He advocates reversing austerity cuts to public services and welfare funding made since 2010, and proposes renationalisation of public utilities and the railways. An anti-war and anti-nuclear campaigner since his youth, he broadly supports a foreign policy of military non-interventionism and unilateral nuclear disarmament.
Corbyn began his career as a representative for various trade unions. His political career began when he was elected to Haringey Council in 1974; he later became Secretary of Hornsey Constituency Labour Party, and continued in both roles until elected MP for Islington North. As a backbench MP he was known for his activism and rebelliousness, frequently voting against the Labour whip, including when the party was in government under Tony Blair and Gordon Brown. Corbyn was also the national chair of the Stop the War Coalition from 2011 to 2015.
