A 'party congress' is a general conference of a
political party. The congress is attended by delegates who represent the party membership. In most parties the party congress is the highest decision making body of the organisation and elects the party's leadership bodies such as the
National Executive Committee in the case of the
British Labour Party or the
Central Committee in the case of
Communist parties. Party congresses are also responsible for making policy decisions for the party and deciding the party's general direction.
In the
United Kingdom, the term
party conference is used instead. In the United States and Canada,
political convention is the preferred term.
