Multiparty political systems are found in many countries that have parliamentary governments. Countries with multiple parties include Belgium, Denmark, France, Italy, Japan, and Sri Lanka. Most multiparty countries have four or five major
parties and, in addition to these, there may be many minority partibs. In most cases, each of these political parties has
particular economic or social goals. Multiparty systems vary from country to country. Most multiparty systems consist of
a few left-wing parties, which hold liberal or radical views, some center parties, which have moderate views, and a few
right-wing parties, which support conservative views. In multiparty countries, one party seldom wins enough seats in the
legislature to form a majority. Therefore, two or more of the parties will join forces and form a coalition government to
direct the nation's affairs. Often the coalition parties fall to agree on policies and programs because of the differences in
their political bellefs; therefore, the government ultimately falls. In the United States, the system of government is
considered a two-party system, where the checks and balances of each party against each other is fairly even; the one
party will win some legislative galns, and then the other will. The multiparty system is not as simplified as that. The
multiparty system tends to produce a less stable government than does the two-party system.
