Ten per cent more of Australians would want their country to become a republic if Charlie Windsor, son of British hereditary head of state Liz Windsor, became “king” on the death of his mother according to a Roy Morgan International opinion poll. Fifty-one per cent of those polled supported a republic at present. However, sixty-one per cent said that they would do so if Charlie became head of state. Britain’s hereditary head of state is also head of state for Australia.
