Which of the following is NOT a role of MPs in the House of Commons?

Members of Parliament (MPs) in the House of Commons have distinct roles, primarily aimed at representing their constituents, participating in the legislative process, and holding the government accountable. Questioning ministers allows MPs to scrutinize government actions and policies, providing a check on executive power. Debating bills is a fundamental aspect of the parliamentary process, where MPs discuss proposed legislation, share their views, and contribute to lawmaking. Raising issues for constituents involves MPs advocating for the concerns and needs of their local communities, ensuring that their voices are heard in broader political discussions.

Conducting judicial reviews, however, falls outside the responsibilities of MPs in the House of Commons. Judicial reviews are performed by the judiciary to evaluate the lawfulness of actions taken by public bodies, and they are not within the remit of parliamentary duties. This distinct function underscores the separation of powers in the UK government, where the legislative, executive, and judiciary branches have separate roles and responsibilities. Therefore, identifying judicial reviews as not being a role of MPs correctly highlights the specific functions that MPs are tasked with in their legislative capacity.
