BUDAPEST, March 29 (Xinhua) -- Hungarian Prime Minister Viktor Orban campaigned hard on Saturday, calling on supporters to vote in the upcoming parliament's election, though the polls showed that he is likely to win the next four-year term.

Orban is the candidate for prime minister of the ruling central-right Fidesz Party and the Christian Democratic People's Party.

Addressing the election rally at Heroes' Square in Budapest to the hundreds of thousands of supporters, Orban voiced his satisfaction with his governance to date, calling the past four years "uNPRecedented" in achievements, and the country has seen its economy growing.

Seeking another four-year term, the prime minister vowed to give more cares to elder population, improve education and boost employment.

In the latest polls, Leftist groups led by the Socialist Party came as the second, winning about 20 percent of support, followed by the far-right Jobbik party which gained about 15 percent of support, while Orban obtained around 50 percent.

Gabor Vona of the far-right Jobbik party said that neither Fidesz nor the Socialists had produced a substantive platform, charging both with unrealistic ideas regarding Hungary's future.

Hungary's parliament election is scheduled to hold on April, 6.
