Members may seek clarification of the answer to an oral question or attempt to obtain further information through the use of supplementary questions. A supplementary question is posed immediately following a response to an initial question.
The Speaker retains the authority to determine when supplementary questions may be permitted. The guidelines that apply to initial questions also apply to supplementary questions.
A supplementary question is meant to flow from or to be based on the response of the Minister or Parliamentary Secretary to the initial or preceding question.
However, the Speaker will not insist that a supplementary question be related to the main question. It is acceptable for a Member to direct a supplementary question on a different topic to a different Minister or for a party to split a round of questioning between two Members, with each one asking a different question to a different Minister.
