The group, upon formally repudiating Trotskyism, renamed themselves the International Leninist Workers Party and later the Economic and Philosophic Science Review.

The ILWP/EPSR are avowedly Marxist-Leninist and supportive of the Soviet Union model but critical of its party's revisionism which they attribute to Joseph Stalin's political errors.

They are also very strongly supportive of Sinn Féin (and until its dissolution, of the Irish Republican Army) and many Third World national liberation movements.

This gathered steam such that by the 1990s it was mainstream policy among far-left publications; the EPSR rejected the stance in 1999 outright as anti-social, saying homosexuality had "obvious disadvantages for any species in evolutionary terms".
