Workers' Institute of Marxism–Leninism–Mao Zedong Thought

The Workers' Institute of Marxism–Leninism–Mao Zedong Thought was a British political organisation based in Brixton, London. It was formed by Aravindan Balakrishnan in 1974 after his expulsion from the Communist Party of England (Marxist–Leninist). Many of its members lived in a commune originally located at its headquarters. In the early 1980s, after a police raid, Balakrishnan decided to move the group's activities underground.

Balakrishnan's control over his followers intensified and the commune moved between several addresses. The group ended in 2013 with the arrest of Balakrishnan and his wife, Chandra, under the suspicion of multiple charges including rape, false imprisonment, and domestic abuse. The three remaining members were taken to safety, including Katy Morgan-Davies who was born into the sect.
