More than 6,500 candidates from different political parties, movements and coalitions are fighting for 466 seats in the bicameral Romanian parliament (Senate and Chamber of Deputies). Polling stations across Romania opened at 7 a.m.
The main contenders are pro-president National Liberal Party and the Social Democratic Party.
The exit polls data shows that the favorite of the elections is the Social Democratic Party, which may gain 40-44% of votes, followed by the center-right National Liberal Party with 18-27% of the votes.
Earlier, the Social Democratic Party was removed from power after its leader Liviu Dragnea was sentenced to two years probation on charges of data falsification about referendum turnout in 2012.
The Romanian parliament consists of two chambers and is elected for four years.
Presently, a technocratic government is in power in the country, which was formed in 2015 after the resignation of Prime Minister Victor Ponta and his cabinet.
Ponta was forced to leave his post on a background of mass protests after a fire in a nightclub in Bucharest, where 64 people died.
