 Although the bailiwicks of Jersey and Guernsey are often referred to collectively as the Channel Islands, the "Channel Islands" are not a constitutional or political unit.Jersey has a separate relationship to the Crown from the other Crown dependencies of Guernsey and the Isle of Man, although all are held by the monarch of the United Kingdom.Jersey is a self-governing parliamentary democracy under a constitutional monarchy, with its own financial, legal and judicial systems, and the power of self-determination.
