Following the Argentine surrender at the end of the Falklands War, the British Governor returned and it was decided that the Government of the Falkland Islands should be modernised. In 1985 the Constitution of the Falklands came into force which greatly reduced the power of the Governor, making the office more accountable to the Executive Council of the Falkland Islands and creating in law a new post of Chief Executive, to which many powers of the Governor were delegated. In 2009 a new constitution was established which further defined the role and powers of the Governor.
