what is the role of the king and queen in england
Monarchy of the United Kingdom The monarch and his or her immediate family undertake various official, ceremonial, diplomatic and representational duties. As the monarchy is constitutional, the monarch is limited to non-partisan functions such as bestowing honours and appointing the Prime Minister. The monarch is commander-in-chief of the British Armed Forces. Though the ultimate formal executive authority over the government of the United Kingdom is still by and through the monarch's royal prerogative, these powers may only be used according to laws enacted in Parliament and, in practice, within the constraints of convention and precedent.
Kingdom of England The standard title for monarchs from Æthelstan until John was Rex Anglorum ("King of the English"). Canute the Great, a Dane, was the first to call himself "King of England". In the Norman period Rex Anglorum remained standard, with occasional use of Rex Anglie ("King of England"). From John's reign onwards all other titles were eschewed in favour of Rex or Regina Anglie. In 1604 James I, who had inherited the English throne the previous year, adopted the title (now usually rendered in English rather than Latin) King of Great Britain. The English and Scottish parliaments, however, did not recognise this title until the Acts of Union of 1707.
