Answer:
Monarchy is the oldest form of government in the United Kingdom. In a monarchy, a king or queen is Head of State. The British Monarchy is known as a constitutional monarchy. This means that, while The Sovereign is Head of State, the ability to make and pass legislation resides with an elected Parliament.
Step-by-step explanation:
In the Kingdom of England, the Glorious Revolution of 1688 led to a constitutional monarchy restricted by laws such as the Bill of Rights 1689 and the Act of Settlement 1701, although limits on the power of the monarch ("a limited monarchy") are much older than that (see Magna Carta).
