Budapest: Hungarian Prime Minister Viktor Orban's Fidesz party has lost the two-thirds supermajority it held in parliament since 2010, which allowed it to pass a new constitution and other legislation without input from the opposition.

The National Election Office said yesterday that Zoltan Kesz, an independent supported by the left-wing opposition parties, defeated Fidesz candidate Lajos Nemedi in a district centered on the city of Veszprem.
