BUDAPEST, May 26 (Xinhua) -- In his speech following a landslide victory in the European Parliament elections, Hungarian Prime Minister Viktor Orban said Sunday he would cooperate with everybody in Europe who wanted to stop migration.

"We have a record victory with a record turnout. We know that with the migration a new era had begun. That is why we can say it was a historic victory," Orban told at a press conference.

He thanked the people voting for him in "choosing that Hungary remain to the Hungarians".

Orban said his victory meant a mandate for three things -- to stop migration everywhere in Europe, to protect the "Europe of nations" and to defend the Christian culture.

"The strengthening of the liberals and the greens in Europe mean for Hungary that Orban will have to face fierce adversaries in the European Union, as most critics regarding the Hungarian government from the EU came from these two factions, who became stronger after tonight," Zoltan Somogyi, the founder of think tank Political Capital told Xinhua after the elections.

Somogyi recalled that the report adopted against the Hungarian government by the European Parliament last September had been elaborated by green MEP Judith Sargentini.

"Within Hungary, the fact that DK will send 4 deputies to the second biggest (S&D) faction of the EP will give ammunition to DK in the future," the expert added.

Orban's ruling Fidesz-KDNP party alliance won a landslide victory securing 52.1 percent of the votes and 13 seats of the European Parliament, according to official figures here on Sunday, in line with expectations.

The second winner was the Democratic Coalition (DK), a pro-European party which called for the "United States of Europe" in its campaign. They gained a surprise 16.3 percent (versus around 10 in the polls) that earned them 4 seats in the EP.

The third place went to Momentum, a young liberal formation, also pro-European, they can send two deputies with their score of 9.9 percent.

The alliance of leftist Socialist (MSZP) and green liberal Parbeszed (Dialogue) secured only one seat with 6.7 percent, just like the nationalist Jobbik, with 6.4 percent.
