By having legislatures, the Marxist–Leninist parties try to keep ideological consistency between supporting representative institutions and safeguarding the leading role of the party. The seek to use the legislatures as a linkage between the rulers and the ruled. These institutions are representative and usually mirror the population in areas such as ethnicity and language, "yet with occupations distributed in a manner skewed towards government officials." Unlike in liberal democracies, legislatures of communist states are not to act as a forum for conveying demands or interest articulation—they meet too infrequently for this to be the case. This might explain why communist states have not developed terms such as delegates and trustees to give legislature representatives to vote according to their best judgement or in the interest of their constituency. Scholar Daniel Nelson has noted: "As with the British parliament before the seventeenth-century turmoil secured its supremacy, legislative bodies in communist states physically portray the 'realm' ruled by (to stretch an anaology) 'kings'. Members of the assemblies 'represent' the population to whom the rulers speak and over whom they govern, convening a broader 'segment of society' [...] than the court itself." Despite this, it does not mean that the communist states use legislatures to strengthen their communication with the populace—the party, rather than the legislature, could take that function.
