The National Assembly, or the parliament, is Bulgaria's legislative body. It also elects the government by a simple majority, and has a four-year term -- except in certain circumstances such as when it is unable to elect a government.

This is Bulgaria's fifth parliamentary elections in two years. The previous elections were held on Oct. 2 last year, but the legislature was dissolved after the parliamentary parties failed to form a ruling majority.
