Platform (European politics)

Platforms, in European politics, are openly organized political factions within left-wing political parties. Examples include the Republican Communist Network, the Workers Unity Platform and the Solidarity Tendency, platforms within the Scottish Socialist Party; the Socialist Workers Platform and the Committee for a Workers' International (International Socialists) platform, both Trotskyist platforms formerly within the Scottish Socialist Party and now part of Solidarity (Scotland); and the "plateformes" 1 through 4 of the Revolutionary Communist League (Ligue communiste révolutionnaire - LCR) in France.

Such groups in American left-wing political organizations are usually called tendencies or caucuses.
