The French equivalent, ultra-gauche, has a stronger currency, as it is a more positive term in that language and is used to define a movement that still exists today: a branch of left communism descending from theorists such as Amadeo Bordiga, Otto Rühle, Anton Pannekoek, Herman Gorter and Paul Mattick, and continuing with more recent writers, such as Jacques Camatte and Gilles Dauvé.
