What titles should you use to address the President of the meeting?

Addressing the President of a meeting correctly is essential in parliamentary procedure, as it reflects respect for the authority and role of the presiding officer. The titles "Madam President" or "Mr. President" are the appropriate forms of address recognized in formal settings. Using these titles acknowledges the individual's position in a traditional and respectful manner that is consistent with parliamentary norms.

Other options may not provide the same level of recognition or respect. While "Sir / Madam" is a polite form of address, it is too generic and does not specifically acknowledge the role of the President in the context of a meeting. Similarly, "Mr. / Ms. Leader" is not a standard title for the presiding officer and may not convey the specific authority associated with the position. The titles "Chair / Secretary" refer to other roles within the meeting structure and may confuse the hierarchy being addressed. Thus, "Madam / Mr. President" is clearly the correct choice.
