Anna Di Carlo is National Leader of the MLPC. Anna has played an active role in elaborating the MLPC's program of democratic renewal since 1989. An expert in the party-dominated system of representative democracy, she represents the MLPC on the Elections Canada Advisory Committee of Registered Political Parties and prepares briefs on behalf of the MLPC to the government regarding changes to the electoral laws. She has consistently opposed electoral reforms which have strengthened the power and privilege of the political parties of the establishment and argued out the position of the MLPC that the starting point of electoral reform must be to bring about changes which will guarantee that all members of the polity can exercise the Charter-recognized right to elect and to be elected. She is dedicated to eliminating the inequalities that currently exist based on a person's status in the society in terms of wealth and access to the levers of political power.

Anna has been a member of the Party since 1978.

Sandra L. Smith is President of the MLPC and Director of the Party's institute of ideological studies and editor of its papers and theoretical journals. 

A founding member of the Party, Sandra has played a leading role in all its main work throughout the years. She is particularly known nationally and internationally for her work on the modern definition of rights and their defence. She has put forward the thesis that people have inviolable rights by virtue of being human, that modern definitions of economic, political, social, cultural and collective rights stem from this reality, and that society must harmonize the rights of the individual with those of their collectives, and those of individuals and their collectives with the general interests of society. This thesis is central to the call for the working class to constitute itself the nation and vest sovereignty in the people. The aim is to open society's path to progress by recognizing the claims of all its members upon it. On the basis of this work, Sandra champions the recognition of the right of Quebec to self-determination, the hereditary rights of the First Nations, and the affirmation of the collective rights of women, youth and students, the working class, national minorities, the impoverished, the disabled, and all others.
