 Guided by socialist principles, Manley was not a doctrinaire socialist.PNP socialism during the 1940s was similar to British Labour Party ideas on state control of the factors of production, equality of opportunity, and a welfare state, although a left-wing element in the PNP held more orthodox Marxist views and worked for the internationalisation of the trade union movement through the Caribbean Labour Congress.In those formative years of Jamaican political and union activity, relations between Manley and Bustamante were cordial.
