Hungarians vote Sunday in parliamentary elections that are expected to produce a landslide victory for conservative Prime Minister Viktor Orban party, dpa reported. Since the last elections in 2010, Orban and his Fidesz party have governed with a more than two-thirds majority in parliament. According to opinion polls, the only uncertainty is whether Orban will again have the same strong backing in parliament. Surveys have tipped Fidesz to win 47 per cent of the votes, the opposition Socialist Party 23 per cent and the far-right Jobbik party 21 per cent.
