Viktor Orban, the European Union's longest-serving leader, conceded defeat on Sunday after 16 years in power as Hungarians voted in record numbers for a pro-European course spearheaded by centre-right rival Peter Magyar.
With more than 98% of votes counted, Magyar's Tisza party is projected to win 137 seats in the 199-member parliament, a crucial two-thirds majority that will allow the new government to reverse Orban's controversial reforms and rewrite the constitution.
