Factbox: Five facts about Viktor Orban of Hungary's Fidesz

BUDAPEST (Reuters) - The Hungarian opposition Fidesz party is forecast to win by a landslide in a parliamentary election Sunday, opinion polls say.

Followings are facts about Fidesz Chairman Viktor Orban, who is poised to become the country's new prime minister.

* Orban, 46, a trained lawyer, will start his second term as prime minister after spending the past eight years of Socialist rule in opposition. He headed a Fidesz government between 1998 and 2002, in coalition with the agrarian populist Smallholders' Party.

* A founder of Fidesz in 1988, Orban rose to fame when he demanded Soviet troops get out of Hungary during a 1989 reburial ceremony of 1956 prime minister Imre Nagy. Orban has been the figurehead of Fidesz since the party was founded.

* As prime minister, Orban advocated a growth-centered economic policy. While maintaining a relatively frugal fiscal regime, his government initiated a program that distributed around 100 billion forints ($500 million) mostly to local small and medium enterprises to invigorate the economy.

* Though the party got into parliament in 1990 on a liberal platform and focused its policies on young voters, Orban subsequently transformed Fidesz into a mainstream conservative group, appealing to the middle class and entrepreneurs.

* Orban himself also appeals to many ordinary Hungarians with his rural preferences and down-to-earth approach. He is a keen amateur soccer player. He is married with five children.
