Hungarian opposition leads Orban's Fidesz, poll shows

Hungary's center-right Tisza party is leading Prime Minister Viktor Orban's ruling Fidesz ahead of parliamentary elections scheduled for Sunday, a poll published by the Nepszava newspaper showed on Friday.

Nationalist-leaning Orban faces the biggest challenge to his rule in 16 years, although a large number of undecided voters means the outcome of the election remains uncertain, Reuters reports.

The survey, conducted on a sample of 1.000 respondents, showed that Tisa has the support of 38 percent of all voters, while Fidesz has the support of 29 percent. About 25 percent of respondents said they had not yet decided how they would vote.
