Oral questions are usually seen as a procedure designed for political conflict. Yet question time may serve other purposes depending on the institutional setting, the political context and the policy field. By comparing the use of oral questions on the defence issue in the national parliaments of four Western democracies, the paper identifies a specific characteristic of questioning in each lower house: political conflict in Germany, internal dissent in the United Kingdom, reward of policy expertise in Spain and local issues in France. Such diverse uses of questioning procedures impact differently on the quality of the accountability process.
