Sri Lanka swore in Marxist leader Anura Kumara Dissanayake as new president Monday following an election in which voters rejected the old political establishment blamed for the country’s economic crisis.

Dissanayake, 55, who ran as head of the Marxist-leaning National People’s Power coalition, defeated opposition leader Sajith Premadasa and 36 other candidates in Saturday’s election.

Dissanayake received 5,740,179 votes, followed by Premadasa with 4,530,902.

In a brief speech, the new president pledged to work with others to take on the country’s challenges.

“We have deeply understood that we are going to get a challenging country,” Dissanayake said. “We don’t believe that a government, a single party or an individual would be able to resolve this deep crisis.”

Just before the swearing-in, Prime Minister Dinesh Gunawardena resigned, clearing the way for the new president to appoint a prime minister and a cabinet.

The election came as the country seeks to recover from its worst economic crisis and resulting political upheaval.

He’s the ninth person to hold Sri Lanka’s powerful executive presidency, created in 1978 when a new constitution expanded the office’s powers.

Dissanayake’s coalition is led by the Janatha Vimukthi Peramuna, or People’s Liberation Front, a Marxist party that waged two unsuccessful armed insurrections in the 1970s and 1980s to capture power through socialist revolution.

After its defeat, the JVP entered democratic politics in 1994 and has been mostly in opposition since then. However, they have supported several previous presidents and been part of governments briefly.

The NPP also includes groups representing academics, civil society movements, artists, lawyers and students.

Dissanayake was first elected to Parliament in 2000 and briefly held the agriculture and irrigation minister portfolio under then-President Chandrika Kumaratunga. He ran for president for the first time in 2019 and lost to Gotabaya Rajapaksa.

Dissanayake’s first major challenge will be to act on his campaign promise to ease the crushing austerity measures imposed by his predecessor Ranil Wickremesinghe under a relief agreement with the International Monetary Fund.

Wickremesinghe has warned that any move to alter the basics of the agreement could delay the release of a fourth tranche of nearly $3 billion.

That economic crisis resulted from excessive borrowing to fund projects that did not generate revenue, the impact of the COVID-19 pandemic, and the government’s insistence on using scarce foreign reserves to prop up its currency, the rupee.

It led to shortages of essentials such as food, medicines, cooking gas and fuel in 2022, triggering massive protests that forced then-president Rajapaksa to flee the country and resign.

Wickremesinghe, then prime minister, was elected by Parliament to fill the remainder of Rajapaksa’s term.
