Hungary's election could end Orban's long rule

Hungary is holding a national election that many see as the most serious challenge yet to Prime Minister Viktor Orban's long rule. His main opponent is Peter Magyar, who has formed a new political movement and is directly challenging Orban's Fidesz party.

Polls suggest Orban's party could lose its majority, which would be a historic defeat. In the final days of the campaign, the two candidates have been trading public accusations.
