In some common law jurisdictions a distinction is drawn between "corporation aggregate" (such as a company, which is composed of a number of members) and a "corporation sole", which is a public office of legal personality separated from the individual holding the office (both entities have separate legal personality). Historically most corporations sole were ecclesiastical in nature (for example, the office of the Archbishop of Canterbury is a corporation sole), but a number of other public offices are now formed as corporations sole.
