this is the house of commons, where Members of Parliament take their seats on the green leather benches according to their party and position. One of them is chosen to be the Speaker, who acts as a chairman of the debates. In front of him on his right the MPs of the biggest party, which forms the government, and facing them sit the MPs of the parties who oppose them, the Opposition. The leaders of these two groups sit at the front on each side. MPs without special positions in their parties sit behind their leaders at the back. They are called backbenchers. The leader of the government, the Prime Minister, sits on the government bench next to his or her ministers. The most important ministers form the government. The minister responsible for the relations with other countries and security is called the Foreign Secretary. The one responsible for law and security is called the Home Secretary. The one who deals with financial matters is called the Chancellor of the Exchequer. Opposite this group sits the Leader of the Opposition and the Shadow Cabinet, each member of which specializes in a particular area of government.
