Bulgaria’s presidential election is heading for a run-off on 1 November after incumbent Iliana Yotova led Sunday’s first round but fell well short of the majority required to win outright. The result was closer than pre-election polling had indicated, leaving her challenger, former caretaker prime minister Andrey Gyurov, within reach of the presidency.

An Alpha Research exit poll put Yotova and her running mate, Kiril Valchev, on 35.3 per cent, and Gyurov and his running mate, Georgi Kandev, on 32.4 per cent. Other agencies produced slightly different estimates, but all placed the two tickets in the lead and showed a narrow gap. These figures are preliminary; Bulgaria’s Central Election Commission has yet to confirm the official result.

The outcome contrasts with pre-election surveys that gave Yotova a sizeable advantage. A Market Links poll published before voting put her well ahead of Gyurov. The first-round estimates instead suggest that the contest has tightened as voters weighed the candidates’ positions on foreign policy, domestic economic pressures and the direction of the government.

Yotova became president in January after Rumen Radev resigned to enter parliamentary politics. She had served as his vice-president for nine years and is now seeking a five-year mandate in her own right. Her candidacy is backed by Radev’s Progressive Bulgaria party and the Bulgarian Socialist Party. The election is the first nationwide test of Radev’s influence since Progressive Bulgaria won April’s parliamentary election. A Yotova victory would leave the presidency and government in the hands of political allies.

Gyurov, an economist and former deputy governor of the Bulgarian National Bank, served as caretaker prime minister earlier this year. He is supported by pro-Western reformist parties. During his premiership, his government signed a security co-operation agreement with Ukraine, and he has argued for closer co-operation with Western allies.

Their foreign-policy differences have been a defining feature of the campaign. Yotova has called for negotiations to end Russia’s war against Ukraine and for better relations with Moscow. Gyurov has taken a more supportive position towards Kyiv. The choice reflects a longstanding debate in Bulgarian politics over how the country should balance its relationship with Russia against its EU and NATO commitments.

The war’s impact on the Black Sea has given that debate a direct security dimension. Drone attacks on commercial vessels near Bulgaria’s coast have raised concerns about shipping safety and the conflict’s potential to spread. The government has sought support from its partners to strengthen maritime security. Both leading candidates condemned the attacks, while their differences over the wider war have kept Bulgaria’s response and its ties with Moscow in focus. The attacks on merchant shipping were a prominent issue during the campaign.

Rising energy prices and inflation have also featured in the campaign, as households face pressure from the cost of living. Those concerns may matter to voters who backed neither of the two leading tickets. The second round will require Yotova and Gyurov to appeal beyond their first-round supporters, while also persuading voters who did not participate to return to the polls.

Revival party leader Kostadin Kostadinov placed third. His ticket with Petar Volgin received 12.6 per cent in the Alpha Research exit poll, though other estimates were higher. Kostadinov has opposed military support for Ukraine; Ukraine imposed a ten-year entry ban on him in 2022. His supporters could influence the run-off, but their votes should not be treated as a single bloc: some may back Yotova, others Gyurov, and some may stay at home.

Turnout was exceptionally low. Alpha Research estimated participation at 22.3 per cent by 7pm, with other agencies reporting similarly low figures. The Bulgarian constitution requires more than half of eligible voters to participate and a candidate to receive more than half of valid votes for a first-round victory. Neither threshold was met. Polling analysis cited election fatigue after April’s parliamentary vote and the fact that the presidential election was held separately.

The low participation makes Sunday’s estimates an uncertain guide to the run-off. A higher turnout could change the balance, particularly if one candidate succeeds in mobilising voters who stayed away or attracting supporters of eliminated candidates.

The presidency is largely ceremonial, with executive authority resting mainly with the prime minister and parliament. It nevertheless carries political weight: the president leads the armed forces, can veto legislation, signs international treaties and appoints ambassadors. The 1 November vote will decide whether Yotova secures a mandate of her own and consolidates the governing camp’s position, or whether Gyurov can turn his stronger-than-expected first-round showing into a change at the top of the state.
