Voters in 21 EU countries, including France and Germany, will wrap up a four-day European Parliament election on Sunday.
This election is expected to shift the assembly to the right and increase the number of eurosceptic nationalists.
The outcome will influence how the EU, a bloc of 450 million people, addresses challenges such as a hostile Russia, competition from China and the U.S., climate change, and immigration.
The voting began on Thursday in the Netherlands and continued in other countries through Saturday, with most votes being cast on Sunday.
An EU-wide exit poll will be released at around 20:30 CET, followed by provisional results after 23:00 CET, NBC News reported.
Opinion polls suggest that pro-European liberals and Greens will lose seats, weakening the center-right and center-left majority and complicating the passage of new EU laws and further integration.
Many voters are concerned about the cost of living, migration, and geopolitical tensions, including the war in Ukraine.
