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.

A George Simion victory could isolate Romania, erode private investment and destabilise NATO's eastern flank, where Ukraine is fighting a three-year-old Russian invasion, political observers say.

George Simion, leader of the hard-right Alliance for the Unity of Romanians, emerged as the clear frontrunner in Romania ’s presidential election redo, securing 40.5 per cent of the vote with nearly all ballots counted. The vote followed last year’s annulled election marred by allegations of fraud.
