The Leader of the Labour Party is the senior political figure and principal public representative of the Labour Party in the United Kingdom. The leader acts as the party's chief strategist and spokesperson, guides its parliamentary presence and is the principal individual to whom media, other parties and the public look for the party's position on major issues. Since 4 April 2020 the office has been held by Keir Starmer, who sits for the constituency of Holborn and St Pancras. The role is often described simply as the party's leader or head.

Roles and responsibilities

The leader has a range of political and organisational duties. In Parliament they lead Labour's MPs, set priorities for the parliamentary party and normally select or influence the composition of the frontbench team (shadow cabinet) when in opposition. As the public face of Labour they present the party's programme, take part in national debates and steer campaign strategy at general elections. When Labour is the largest opposition party the leader serves as Leader of the Opposition; when Labour forms the government the party leader normally becomes Prime Minister.

Selection and tenure

Leadership elections are held when a leader resigns, is challenged, or their term otherwise ends. In contemporary practice the outcome is decided by a vote that includes party members, registered supporters and affiliated organisations; the system has evolved from earlier electoral colleges to a more direct voting model introduced in the 2010s. Candidates are usually serving Members of Parliament and must secure nominations from a proportion of Labour MPs to appear on the ballot.

History and development

The office was formally established in 1922. Before that, from the first Labour MPs in 1906 until the early 1920s, the senior parliamentary figure was known as the Chairman of the Parliamentary Labour Party. Over the decades the position expanded from organising MPs to becoming the chief architect of party policy and the principal national representative. Prominent holders of the post have later become Prime Minister or Leader of the Opposition, reflecting the central political significance of the office within British politics.
