Answer
Klaus Iohannis, a former mayor of Sibiu, defeated Victor Ponta in the 2014 Romanian presidential election. Ponta, the incumbent prime minister at the time, represented the Social Democratic Party while Iohannis ran as an independent supported by the National Liberal Party and the Democratic Liberal Party. The election marked a significant shift in Romanian politics, as it ended the Social Democratic Party's dominance and brought a center-right coalition to power.
