The activities of Parliament in Britain are more or less the same as those of the parliament in any western democracy. It has legislative power, which means it makes laws, gives authority for the government to raise and spend money, keeps a close eye on government activities and discusses these activities.

The British Parliament works in a large building called the Palace of Westminster (popularly known as the Houses of Parliament). This contains offices, committee rooms, restaurants, bars, libraries, and even some places of residence. It also contains two larger rooms. One of these is where the House of Lords holds its meetings. The other is where the House of Commons holds its meetings. The British Parliament is divided into these two ´houses´, or chambers, it means it is bicameral and its members belong to one or other of them. However, only members of the Commons are known as MPs (Members of Parliament). The Commons is by far the more important of the two.
