The country is made up of 26 cantons or states, which form the confederation. The leader of the government is the president. Both the president and vice president are elected by the Federal Assembly from the Federal Council. They serve a one-year term. Elections are usually held in December. Representatives of the cantons are elected to the assembly for four-year terms.
