Guernsey and Jersey are both administered by parliaments known as the States. These parliaments are independent of the British Government but legislation in both islands is subject to approval by the Privy Council on behalf of the reigning monarch.
Although the systems of government in each island are broadly similar, there are differences in some areas, and the role and function of the States of each island has evolved gradually over hundreds of years.
Alderney's parliament is also known as the States. It has a degree of autonomy in some matters but is subject to control from Guernsey on others.
