Germany's parliamentary election is a tight race between the center-left Social Democratic Party and Chancellor Angela Merkel's center-right coalition.
German public broadcaster ZDF says as of 10 p.m. the Social Democrats are expected to gain 26 percent of the vote while the coalition of the Christian Democratic Union and the Christian Social Union is likely to receive 24.5 percent.
ZDF also estimates that the environmentalist Greens will secure 13.9 percent, and the center-right Free Democratic Party will get 11.7 percent.
The election has been drawing keen interest both within and outside Germany as it will decide who will succeed Merkel as chancellor.
Merkel has led the country for 16 years in the post, demonstrating her powerful leadership, both on the domestic and international fronts.
No individual party is expected to win a majority of seats on its own, raising the need for talks to form a coalition government.
