British Armed Forces
The Commander-in-Chief of the British Armed Forces is the British monarch. Members of the British Armed Forces must swear allegiance that they will obey the orders of the monarch. Under the constitution of the United Kingdom, the armed forces controlled by the Crown, but because of the 1689 Bill of Rights, the British may not have an army during peacetime unless the British Parliament allows it. However, the British Parliament now passes an Armed Forces Act every five years as a formality. The British Prime Minister is the de facto commander of the British Armed Forces, which are managed by the Ministry of Defence.
