Six candidates sparred in French at the final official debate of the Conservative Party of Canada leadership race on Wednesday. Ahead of the September vote, some say front runners Pierre Polievre, Jean Charest and Patrick Brown are fighting for the soul of the party.

Our question this week: Who should be the next federal Conservative leader? What's at stake for Canada?

Sally Zhou, a University of British Columbia student and president of the campus group UBC Conservatives, shares why she believes Pierre Polievre should be the party's next leader; Former Conservative MPs Lisa Raitt and Peter McKay weigh in on the leadership race thus far; and Zain Velji, a partner at the marketing and communications firm Northweather, and Ken Boessenkool, a fellow at the C.D. Howe Institute, discuss the candidates' campaign strategies.
