(ANSA-AFP) - BUDAPEST, FEB 16 - US Secretary of State Marco Rubio has arrived in Hungary for talks with Prime Minister Viktor Orban Monday, ahead of elections where the nationalist leader faces a significant challenge from the opposition. Rubio's visit is the final stage of a whirlwind trip to Europe that also saw him address the Munich Security Conference and visit another right-wing ally, Slovakian Prime Minister Robert Fico. US President Donald Trump has made no secret of his high regard for Orban, saying in a social media post on Friday that the prime minister had produced "phenomenal" results in Hungary. But Orban, 62, has a fight on his hands for the April 12 legislative elections in Hungary. Polls suggest his Fidesz party is trailing opposition leader Peter Magyar's TISZA. In a speech on Saturday, Orban insisted he would keep up his fight against "pseudo-civil organisations, bought journalists, judges, politicians" -- a tirade not unlike those favoured by Trump. He also took aim at the "oppressive machinery of Brussels", another jibe at the European Union's leadership, with whom he has long been at loggerheads on a host of issues. Orban is in the firing line of the EU's leadership for what they say is his silencing of critical voices in the judiciary, academia, the media and civil society. They also accuse him of going after minorities. (ANSA-AFP).
