Indonesians have begun voting for new national and regional parliaments in an election being seen as a test run for a presidential race in July.
Some 19,000 seats are being contested across the country including the 560 seats in the national parliament.
Parties wishing to field candidates in the presidential poll must secure either 20 percent of the seats in the main parliament or 25 percent of the total vote.
Voting is taking place across three different time zones and officials have warned of delays.
Opinion polls predict the opposition Democratic Party of Struggle will do well.
Their candidate Joko Widodo is seen by many in the country as Indonesia’s next president.
The ruling Democratic Party of the current leader President Susilo Bambang Yudhoyono is expected to see its support fall amid several corruption scandals.
