The British Constitution
The constitution of Britain has traditionally been split between royal prerogative statutes, common law, convention, convention and authoritative opinion. But recent external developments such as the European Union (EU) and the European Convention on Human Rights (ECHR) have had a strong influence on Britain.
The Royal Prerogative are a set of privileges that the Royal family since the Middle Ages. However, as the power of the monarchy declined, the power was now with the Prime minister and his cabinet. Some of the Royal Prerogatives include the powers to declare war, make treaties, issue orders to armed forces and dissolve parliament.
