Prerogative power

Those powers formally left with the monarchy in the wake of the United Kingdom Revolution and Bill of Rights of 1688, and that have not subsequently been removed by statute; for example, the conduct of foreign relations and the Royal Prerogative of Mercy.

An inherent power or legal privilege of the Crown, defined in accordance with principles of common law. The prerogative is subject to statute, and today there are very few remaining areas in which the Crown prerogative survives; the vast majority of Crown powers are defined through statute.
