In many democratic republic countries like the Philippines, the ruling party is the party of the elected president that is in charge of the executive branch of government. In parliamentary systems, the majority in the legislature also controls the executive branch of government, thus leaving no possibility of opposing parties concurrently occupying the executive and legislative branches of government.[6] In other systems, such as in an American style presidential system, the party of the president does not necessarily also have a legislative majority.
