The UK public elects 650 Members of Parliament who are called MPs. They are elected to represent the people’s interests and concerns in the House of Commons. MPs consider and propose new laws, rights and issues and can scrutinise government policies by asking ministers questions about current problems either in the Commons Chamber or in Committees.

Once the MPs are elected, they will spend much of their time in Westminster, where the parliament is located. MPs will take their seats in the House of Commons where they will meet to debate new laws and make decisions about how the UK is run. One of an MP's most important roles is to help make and change the laws governing the UK.

The main difference between the House of Lords and the House of Commons is that the House of Commons is made up of about 650 elected Members of Parliament while its counterpart is made up of 700 members. It makes laws, controls the government's finances, and keeps a close eye on government administration.

It is a form of government with a monarch at the head. Monarchy is the oldest form of government in the United Kingdom. In a monarchy, a king or queen is Head of State. The British Monarchy is known as a constitutional monarchy. This means that, while The Sovereign is Head of State, the ability to make and pass legislation resides with an elected Parliament.

The Lords started off as advisors to the king. In 1215, King John was forced to sign the Magna Carta, sharing power with the nobility with the people. By the 14th century Edward III had two groups of advisors divided into chambers, the Lords and the Commons, made up of knights and merchants. In recent times the Commons became increasingly dominant and the King became less powerful this is why the queen today has barely any power compared to parliament who run the country.

The House of Lords has three main functions. To question and challenge the work of the Government, to work with the House of Commons to shape laws and to investigate issues through committees and debates to help improve the way the country is governed.

The house of lords is laid out so the Government party on the one side, the opposition on the other. Members who don’t belong to any political party are known as cross-benchers.

The House of Lords Chamber spends about 60% of its time on legislation; the other 40% is spent on scrutiny – questioning Government and debating issues and policy. Committee work takes place outside the Chamber. 

This is the case in the United Kingdom. In the UK, the executive comprises the Crown and the UK Government, including the Prime Minister and Cabinet Ministers. The executive formulates and implements policy. The legislature, Parliament, comprises the Crown, the House of Commons and the House of Lords.
