International Third Position was a group formed by Nick Griffin and Derek Holland as a continuation of the Political Soldier movement. With a very small membership the ITP preached a form of "left-wing" fascism that attacked capitalism and looked to the Strasser brothers and writers like Hilaire Belloc and G.K. Chesterton for inspiration. Apart from organising a few public meetings for David Irving, and a visit by Griffin and Holland to Libya, the group had minimal impact and was gone by the early 1990s.
International Third Position is also the name of an ideology (after which the British ITP was named) that combines nationalist and socialist elements. They are very similar to the left side of the national socialist movement. This includes such phenomena as National Bolshevism, National Anarchism and Strasserism.
