The United Kingdom's island possessions fall into two constitutional categories—neither is part of the UK proper, but both fall under British sovereignty.
Self-governing; UK handles defense/foreign affairs; not EU/UK parliament.
Constitutionally distinct; King as head of state; UK appoints governors; most have elected governments.
