Rumen Radev's Progressive Bulgaria party looks set to win Sunday's Bulgarian Parliamentary election - the eighth general election in five years.
Exit polls put his Progressive Bulgaria on 37%, more than double the score of the closest runner-up, former prime minister Boiko Borisov's GERB on 16%.
Three or four other parties look set to cross the 4% threshold and enter Parliament.
The election was called after the previous government tried to push through a controversial budget last December, prompting mass demonstrations which Radev, as president, supported.
"People rejected the self-satisfaction and arrogance of old parties and did not fall prey to lies and manipulation. I thank them for their trust," Radev said, in his victory speech.
