Sozialistische Zeitung used to be a fortnightly paper (founded 1986) published by the then section of the United Secretariat of the Fourth International, the VSP. Since the slow collapse and the final winding-up of the VSP, the paper has gone monthly and is offically not a "party organ". In reality it is published by ex-VSP members who have grouped themselves in another organisation, the ISL, which is a sympathising group of the USec in Germany.
