The following is a list of political parties in Monaco. Traditionally Monaco is a one party dominant state with the National and Democratic Union (now, Rally & Issues) in power. Opposition parties were widely considered nonexistent. However, following the 2003 parliamentary election, the Union for Monaco (now, Union Monegasque), a coalition of two parties, won 21 of the 24 seats in the National Council. Following the 2013 parliamentary election, however, Horizon Monaco, a coalition of, Rally & Issues, Synergie Monegasque and Union for the Principality, held the majority of parliamentary seats. Since 2016 a majority of the former ruling coalition have defected from the Horizon Monaco coalition and formed the New Majority coalition in partnership with Renaissance and this coalition now controls the National Council under the leadership of Christophe Steiner.
