Party leader

In a governmental system, a party leader acts as the official representative of their political party, either to a legislature or to the electorate. Depending on the country, the individual colloquially referred to as the "leader" of a political party may officially be party chair, secretary, or the highest political office.

The party leader is often responsible for managing the party's relationship with the general public and leading the competition against political rivals, similar to the role of a party spokesperson. As such, they will take a leading role in developing and communicating party platforms to the electorate.

In many representative democracies, party leaders compete directly for high political office. It is thus typical in such states (notably in the Westminster system) for the party leader to seek election to the legislature and, if elected, to simultaneously serve as the party's parliamentary leader. In several countries utilizing the parliamentary system, if the party leader's political party emerges with a majority of seats in parliament after a general election, is the leading party in a coalition government, or (in some instances) is the largest party in a minority parliament, that party's leader often serves as the prime minister. In countries using the Westminster system, the leader of the largest political party not within the government serves as the leader of the opposition.
