Hungarian Prime Minister Viktor Orbán conceded defeat on Sunday after what he called a ″painful″ election result, ending 16 years in power for a powerful figure in the far-right movement allied with U.S. President Donald Trump and Russian President Vladimir Putin.

“I congratulated the victorious party,″ Orbán told supporters in Budapest. “We are going to serve the Hungarian nation and our homeland from opposition as well.”

Initial official results show opposition leader Peter Magyar’s party dominating the election.
