of the regional cabinet. Political parties can switch sides, end their support for the current president of the regional council and form a new regional cabinet without the need for early elections. Municipal elections Any citizen aged 18 or over can become a municipal councilor. Municipal councilors are elected for four-year terms. Voters can only vote in the municipality where they have registered their permanent address. The number of councilors for each municipality varies from 5 to 55. Each voter has a number of votes corresponding to the number of seats in that particular municipal council, which can be distributed freely across candidates of all political parties. For a party to be eligible for representation, the total number of votes for a party divided by the number of seats in the municipal council and multiplied by the number of candidates nominated by that party must exceed 5% of the total number of valid votes cast in the municipality. The number of votes for a candidate of a party in proportion to the number of all votes cast for that party affects the final order of candidates on the party list. Referendums The Constitution of the Czech Republic mentions referendums only in the context of "a referendum concerning the accession of the Czech Republic to the European Union". There are no other provisions concerning referendums. As such, the only state-wide referendum ever held in the Czech Republic was the Czech European Union membership referendum in 2003. The government of the Czech Republic approved a referendum bill in 2005, but it was never passed by the parliament.
