As well as presenting the electorate with an alternative, it is the Opposition party’s job to hold the Government to account.
The Opposition includes a Shadow Cabinet, which is made up of shadow ministers. These are the politicians who would take up roles like Chancellor of the Exchequer, Home Secretary and Foreign Secretary if their party was to win a general election and get into Government.
The Leader of the Opposition is the leader of the political party with the second highest number of MPs in the House of Commons. The current Leader of the Opposition is Ed Miliband, who is the leader of the Labour Party.
