The main objective behind the parliamentary practice of Question Period is to ensure that the government is held accountable to the people. Rather than being a political accountability tool and a showcase of public discourse, these deliberations are most often displays of vitriolic political rhetoric. I will be focusing my research on the ways in which incivil political discourse permeates the political mediascape with respect to one instance in Canadian politics - the acquisition of the F-35 Lightning II Joint Strike Fighter. I believe that incivility in the political discourse of Question Period must be understood within the mechanics of the contemporary public sphere. By interrogating the complexities of how political discourse is being mediatized, produced and consumed within the prevailing ideological paradigms, I identify some of the contemporary social, cultural and political practices that produce incivility in parliamentary discourse.
