Great Britain

How power is divided:
The united kingdom is considered a constitutional monarchy, this means that the head of the state is the monarch (King or Queen) but his/her power is limited by the constitution. This means that not only the head of state gets a say in the government of the united kingdom. The prime minister who is appointed by the queen holds alot of the power in the government. Just below the queen sits the house of lords and the house of commons. Comparing to the United States government it is similar in the sense that if a bill or law is going to passed it needs to pass through both houses before it is sent to the monarch for his or her approval. The House of Commons hold more legislative power than the House of Lords. The house of Lords responsibility is making laws and checking government actions.
How one gains power:
To gain power in the House of Commons you need to be elected in by the people.The house of commons is the lower house of the bicameral parliaments. Originally to be in the House of Lords it was heredity meaning passed down in the family, but more recently the queen herself has been appointing the Lords. There are two sections of the House of Lords one which is a birth rights and the other is where the Queen of Prime Minister can appoint people.
Political System:
Currently the Prime Minister holds most of the political power. Since there is in fact no written Constitution it falls under a weird category. The legislative branch is represented by Parliament, meaning the Houses. The executive power is held by the prime minister. Who has taken in a role similar to the president of the United States. The judicial power is represented by the Supreme Court. The House of Commons is perhaps the most important because without having an written constitution it makes it hard to control.
