Zauberformel

In Swiss politics, the magic formula (German: Zauberformel, French: formule magique, Italian: formula magica) is an arithmetic formula for dividing the seven executive seats of the Swiss Federal Council between the four ruling parties. The formula was first applied in 1959. It gave the Free Democratic Party (now FDP.The Liberals), the Christian Democratic People's Party and the Social Democratic Party each two seats, while the Party of Farmers, Traders and Independents (now the Swiss People's Party) received one seat.

The formula is not an official law, but rather an agreement amongst the rather large coalition of four parties. After the 2003 general elections, the formula was modified, giving two seats to the SVP/UDC at the expense of the Christian Democrats. This was because the Swiss People's Party received 29% of the votes during the election of the parliament making it Switzerland's largest party by votes.

After the election of Eveline Widmer-Schlumpf to the federal council in Autumn 2007, she was expelled from the SVP/UDC, because she took the seat of Christoph Blocher, the unofficial leader of the SVP. The SVP's other councilor, Samuel Schmid followed her, as he, too, was no longer supported by his own party. They led the establishment of the new Conservative Democratic Party of Switzerland (BDP/PBD). Due to this change, the two seats from the SVP/UDC now belonged to the PDB, although it had only a handful of seats in the parliament.
