had comprised 2 Free Democrats, 2 Christian Democrats, 2 Social Democrats, and 1 Swiss People's Party, but in 2004, the Swiss People's Party took one seat from the Christian Democrats. In 2008 the Conservative Democratic Party split from the SVP, taking both of their Federal Council seats with them. However, the SVP eventually retook both seats, in 2009 and 2015 respectively. The Swiss Federal Constitution limits federal influence in the formulation of domestic policy and emphasizes the roles of private enterprise and cantonal government.

According to Freedom House, an American NGO, Switzerland is among the freest countries in the world, with a 2020 score of 39/40 on political rights and 57/60 on civil liberties (for a combined score of 96/100).

On 18 May 2003, two referendums regarding the future of nuclear power in Switzerland were held.
