BUCHAREST (Reuters) - Romania's hard-right presidential frontrunner George Simion will win the May 18 run-off vote against centrist Bucharest Mayor Nicusor Dan, an opinion survey showed on Wednesday, as the two clashed over worldviews and deficits in a debate.

The front-runner in Romania's presidential election, George Simion, accuses the current government of attacking democracy and says he is the only candidate who hasn’t been tainted by holding power.

Romania's previous presidential election was cancelled over allegations of campaign fraud and Russian interference.
