The Labour Party Conference, or annual national conference of the Labour Party, is formally the supreme decision-making body of the Party.
In the United Kingdom, each major political party holds an annual party conference during the party conference season. In the Labour Party, Conference is the supreme body, although the party leadership has made clear, particularly in recent years, that it will ignore the conference's decisions where it does not agree; constitutionally, a British government must be free to make decisions on behalf of the whole population and cannot be bound by any private body.
Delegates to the conference are elected by Constituency Labour Parties, affiliated trade unions and socialist societies. Currently, affiliated trade unions hold 50% of the votes at the conference – down from 80% in the era before Tony Blair. Some 40% of the votes are wielded by the three largest trade unions (Unite, GMB, UNISON).
