The UK Parliament meets in Westminster, London. It has two parts – the House of Commons and the House of Lords.
The House of Commons is made up of MPs and the Lords in the House of Lords are sometimes known peers.
Members of Parliament (MPs) are elected every five years at a General Election. For the purposes of the General Election, the country is divided into 650 constituencies or areas. Each constituency elects one MP to Parliament. The last General Election was in 2015.
At the 2015 General Election Scotland returned 59 MPs. 56 of the 59 MPs elected were from the Scottish National Party (SNP).
One role of MPs in the UK Parliament is to represent their constituents in areas where the UK Parliament takes decisions eg immigration or defence. MPs either debate or ask questions in the House of Commons or they work in smaller groups known as committees.
Other important roles of MPs in Parliament are to help make laws and to scrutinise (check-up on) the work of the government or investigate issues. The most senior MPs in the governing party (or parties, if there is a coalition) form the Cabinet, of which the Prime Minister is the leader.
