The Syndicalist Party was a left-wing political party in Spain, formed by Ángel Pestaña in 1932. Pestaña, a leading member of the Confederación Nacional del Trabajo (CNT) trade union, formed the party in response to the growing influence of the Iberian Anarchist Federation over the CNT. He and other notable members of the CNT had previously signed a Manifest dels Trenta, which had got them expelled.
