The Bailiwick of Guernsey is a separate jurisdiction in itself, and is in turn also three separate sub-jurisdictions. It does not form part of, and is separate from (but is not independent of, or from) the United Kingdom. The two Bailiwicks of Jersey and Guernsey together make up the Channel Islands. The Islanders have never had formal
Bailiwick of Guernsey government. All three legal jurisdictions need Royal Assent from the Privy Council on its primary legislation. Each jurisdiction raises its own taxation, although in 1949 Alderney transferred its rights to Guernsey. The island of Guernsey has a population of around 63,000 in and forms the legal and administrative centre of the Bailiwick of Guernsey. The parliament of Guernsey and of the nearby inhabited islands of Herm, Jethou and Lihou is the States of Guernsey. With a population of around 1,900 in , Alderney has its own parliament, the States of Alderney, which has ten elected members and an elected president.
