The group was based in Earlsfield, and provided office services to several Black Power and Liberation movements - especially those with sympathies for China.
The group had five main principles: The party was led by a team with a Chairman Alexander Tudor-Hart, who was a prominent if difficult former-CPGB doctor in Tooting, a Secretary Paul Noone, a prominent member of the small Medical Practitioners Union, based in Islington, who was replaced by a South London power station worker, a Guianan Jonny James as Foreign Relations Secretary with a young Deputy Secretary from South London who managed direct relationships with the Legation and largely edited the foreign news content of the newspaper.
South London, Bristol, Birmingham, Dagenham and Oxford branches left to form the "Serve the People" Group and paper, and took with them the close relationship with the Chinese Legation.
The rump of the WPPE split again in 1972 when a section of membership left with Tudor-Hart to form the Committee for a Socialist Programme.
In 1985, it again changed its name, to the Workers' Association (not to be confused with the group linked to the British and Irish Communist Organisation ), but it appears to have disbanded the following year.
