resigns (merely four incumbent members were voted out of the office in over 150 years); this member is almost always replaced by someone from the same party (and often also from the same linguistic group). The Federal Chancellor is the head of the Federal Chancellery of Switzerland, which acts as the general staff of the Federal Council. The Chancellery is divided into three distinct sectors. The Chancellor, currently Walter Thurnherr, is the formal head of the Federal Chancellor Sector, comprising the planning and strategy section, the Internal Services section, the political rights section, the federal crisis management training unit of the Federal Administration and the Records and Process Management section. Two sectors are headed by the Vice-Chancellors: the Federal Council sector headed by Viktor Rossi manages the agenda of the Federal Council's meeting. This sector comprises the Section for Federal Council Affairs, the Legal Section, the Official Publications Centre and the Central Language Services. The Information and Communications Sector is led by Vice-Chancellor André Simonazzi; this role also has expanded to become the official spokesman for the Federal Council in 2000. This sector includes the e-Government Section, the Communication Support Section and the Political Forum of the Confederation. The federal government has been a coalition of the four major political parties since 1959, each party having a number of seats that roughly reflects its share of electorate and representation in the federal parliament. The classic distribution of 2 CVP/PDC, 2 SP/PS, 2 FDP/PRD and 1 SVP/UDC as it stood from 1959 to 2003 was known as the "magic formula". This "magic formula" has been repeatedly criticised: in the 1960s, for excluding leftist opposition parties; in the 1980s, for excluding the emerging Green Party; and particularly after the 1999 election, by the Swiss People's Party, which had by then grown from being the fourth-largest party in the National Council to being the largest. In the 2003 federal election, the Swiss People's Party received (effective 1 January 2004) a second seat in the Federal Council, reducing the share of the Christian Democratic Party to one seat. Legislative branch Switzerland has a bicameral parliament called the Federal Assembly, which is composed by: the Council of States (46 seats, 2 seats per canton, except for six cantons which only have 1), also known as the upper chamber the National Council (200 seats, split between the cantons based on population), also known as the lower
