The WPPE was formed in May 1968. The group had five main principles:
* Serving the people
* Uniting all who can be united against the main enemy
* Active members only
* Maximum initiative for members
* All officials subject to immediate recall by members
The party was led by Paul Noone, a prominent member of the small Medical Practitioners Union. It developed links with the Workers' Party of Scotland (Marxist-Leninist), but suffered a split when a section of members left to form the Committee for a Socialist Programme. The English People's Liberation Army may also have originated in the WPPE.
