PRAGUE — The Czech Republic’s pro-Russia president won a second five-year term Saturday after beating a political newcomer viewed as more Western-oriented in a runoff vote.

With ballots from almost all polling stations counted, the Czech Statistics Office said President Milos Zeman had received 51.5 percent of the vote during the two-day runoff election.

His opponent, former Czech Academy of Sciences head Jiri Drahos, garnered 48.5 percent.

The Czech Constitution limits presidents to two terms. Appearing before supporters Saturday, Zeman, 73, called his win “my last political victory” and said “no political loss will follow.”

He pledged “to work as I have worked so far.”

Drahos conceded defeat and congratulated Zeman on Saturday afternoon. The career scientist and chemistry professor said he planned to stay in politics, but did not provide details.

“It’s not over,” Drahos said.

Zeman, a veteran of Czech politics and former left-wing prime minister, won his first term in 2013 during the Czech Republic’s first presidential election decided by voters, not lawmakers.

Since then, he has divided the nation with his pro-Russia stance, support for closer ties with China, and strong anti-migrant and anti-Muslim rhetoric.

Zeman was one of the few European leaders to endorse Donald Trump’s bid for the White House. He also has proposed a referendum on the Czech Republic’s membership in the European Union like the one held in Britain.

Drahos, 68, who led the Academy of Sciences from 2009 until last year, campaigned on maintaining the country’s ties to the EU and NATO. He ran unaffiliated with a political party.

One of the Czech president’s key responsibilities is picking the prime minister after a general election, power that was on display in the days before the runoff election.

The government led by populist billionaire Andrej Babis since his party placed first in an October election resigned Wednesday after failing to win a confidence vote. Zeman immediately asked Babis, his ally, to try again.

The president had said that even if he lost the election, he would swear Babis in again as prime minister before his term expired on March 8.

The president also appoints members of the Central Bank board and selects Constitutional Court judges with the approval of Parliament’s upper house.

Otherwise, the president has little direct executive power since the country is run by a government chosen and led by the prime minister.
