Contrast the structures of different governments in terms of how many political parties each one allows.

The world's governments differ as to how many political parties they allow. China is ruled by one political party, the Communist party of China. There are other minor parties in China, but they do not actually hold any power. The United States has two major political parties, the Democrats and the Republicans. Other minor parties have evolved in recent years, such as the Green party. Three or more political parties usually leads to a coalition government. Parties must find issues on which to agree. In England, there are three major parties, the Labour, Conservative, and the Liberal Democratic parties. France, Germany, and Belgium also have three or more political parties.
