Its magazine 'Resister' became the leading magazine on South Africa's militarization.

The Commonwealth Secretariat, established in 1965, is the main intergovernmental agency of the Commonwealth, facilitating consultation and co-operation among member governments and countries. It is responsible to member governments collectively.

Based in London, UK, the Secretariat organises Commonwealth summits, meetings of ministers, consultative meetings and technical discussions; it assists policy development and provides policy advice, and facilitates multilateral communication among the member governments. It also provides technical assistance to help governments in the social and economic development of their countries and in support of the Commonwealth’s fundamental political values.

The Communist Party of Great Britain (CPGB) was the largest communist party in Great Britain, although it never became a mass party like those in France and Italy. It existed from 1920 to 1991.
