Belgians are heading to the polls in European Union, national and regional elections Sunday.

Polls opened at 8 a.m. (0700GMT) and the first estimates and exit polls were expected by 6 p.m. (1700GMT). In the national elections Belgians are looking to end months of political limbo after the biggest party in the governing coalition quit over Prime Minister Charles Michel's support for the U.N. migration pact.

Michel has steered a caretaker government doing only day-to-day business since December, but with the country's 8 million voters choosing from more than a dozen parties, chances are that it will prove difficult to quickly form a stable coalition.

Bulgarians are voting in the European Parliament elections after a series of scandals overshadowed the debate on key issues of the EU's future.

Voters on Sunday are casting ballots for their country's 17 seats in the 751-member European Parliament. The vote is seen as a test for the center-right party of Prime Minister Boyko Borissov, which suffered a setback after senior officials were involved in corruption scandals.

Latest surveys show only three parties, belonging to mainstream European political groups, passing the election threshold — the ruling GERB party, the Socialist party, and the liberal MRF.

Projections suggest the nationalist and far-right vote will be split between several smaller parties, which could prevent them from capturing seats in the EU legislature.
