Millions of Europeans have been casting their ballots this week in one of the world's biggest democratic elections. Polls opened in 20 EU countries early on Sunday for the June 6-9 elections for a new European Parliament, the legislative branch of the 27-member bloc. Far-right parties are looking to gain more power amid a rise in the cost of living and farmers’ discontent, while the wars in Gaza and Ukraine are also key topics weighing on the minds of voters.
