Hard-right nationalist George Simion could win Romania’s presidential election run-off on Sunday – a vote being held five months after the original election was annulled.

Here's what to know about Sunday's run-off vote in Romania's presidential election, pitting hard-right eurosceptic lawmaker George Simion against centrist independent Bucharest mayor Nicusor Dan.

Simion opposes military aid to Ukraine, is critical of the EU leadership and supportive of U.S. President Donald Trump. A win for Simion in Romania, an EU and NATO member, would risk isolating the country abroad, eroding private investment and destabilising NATO's eastern flank, political analysts say.
