(ANSA-AFP) - BUCHAREST, MAY 17 - The European Union is bracing for yet another far-right politician to join the 27-nation club of leaders, with George Simion the favourite to win Romania's presidential election on Sunday. Yet, while many in Brussels are wary of Simion's brand of politics -- the nationalist eurosceptic is a big fan of US President Donald Trump -- there is also a keenness not to overplay the impact of a potential victory. "It wouldn't be good news to have a Europhobe but that doesn't mean it's going to bring the (EU) machine to a standstill," said one European diplomat. The vote will be closely watched internationally following the rare annulment of last November's election in the key NATO country of 19 million people. "Naturally we all keep an eye on that," said another European diplomat. Simion gained almost 41 percent of votes in the contest's first round -- double the score of his rival in Sunday's run-off, pro-EU centrist candidate Nicusor Dan. His victory would boost the EU's nationalist camp, already championed by the likes of Hungary's Viktor Orban, Slovakia's Robert Fico, and Italy's Giorgia Meloni. "The populist side will rejoice in having a new unruly kid on the block," said Florent Parmentier, a political analyst at the Jacques Delors Institute, a think-tank. (ANSA-AFP).
