National People's Power Party wins two-thirds majority in Sri Lanka ...

The party of Sri Lanka's new Marxist-leaning President Anura Kumara Dissanayake won a two-thirds majority in parliament, according to official election results on Friday, providing a strong mandate for his program for economic revival.

Mr Dissanayake's National People's Power Party (NPP) won 159 of the 225 seats, according to the Elections Commission.

The size of the victory will enable Mr Dissanayake to carry out sweeping reforms, including the enactment of a new constitution which he promised during the presidential campaign, without having to rely on other parties.

Mr Dissanayake was elected president on September 21 in a rejection of traditional political parties that have governed the island nation since its independence from British rule in 1948.

He received just 42 per cent of the votes, fuelling questions over his party's outlook in Thursday's parliamentary elections. But the party received a large increase in support less than two months into his presidency.

In a major surprise and a big shift in the country's electoral landscape, his party won the Jaffna district, the heartland of ethnic Tamils in the north, and many other minority strongholds.

The victory in Jaffna represents a great dent for traditional ethnic Tamil parties that have dominated the politics of the north since its independence.

Colombo-based political analyst Veeragathy Thanabalasingham said northern voters chose the NPP because they could not find a local alternative to traditional Tamil political parties, with which they were disillusioned.

"The Tamil parties were divided and contested separately, and as a result the Tamil people's representation is scattered," he said.

Of the 225 seats in parliament, 196 were up for grabs under Sri Lanka's proportional representative electoral system which allocates seats in each district among the parties according to the proportion of the votes they get.

The remaining 29 seats — called the national list seats — are allocated to parties and independent groups according to the proportion of the total votes they receive countrywide.

The election comes at a decisive time for Sri Lankans, as the island nation is struggling to emerge from its worst economic crisis. It declared bankruptcy after defaulting on its external debt in 2022.

The country is now in the middle of a bailout program with the International Monetary Fund, (IMF) with debt restructuring with international creditors nearly complete.

Mr Dissanayake said during the presidential campaign that he planned to propose significant changes to the targets set in the IMF deal, which his predecessor Ranil Wickremesinghe, signed.

He said the deal placed too much burden on the people.

However, he has since changed his stance and says Sri Lanka will go along with the agreement.

Sri Lanka's crisis was largely the result of economic mismanagement combined with fallout from the COVID-19 pandemic, which along with the 2019 militant attacks devastated its important tourism industry.

The government also slashed taxes in 2019, depleting the treasury just as the virus hit. Foreign exchange reserves plummeted, leaving Sri Lanka unable to pay for imports or defend its currency.

Sri Lanka's economic upheaval led to a political crisis that forced then-President Gotabaya Rajapaksa to resign in 2022. Parliament then elected Mr Wickremesinghe to replace him.

The economy was stabilised, inflation dropped, the rupee strengthened and foreign reserves increased under Mr Wickremesinghe.

Nonetheless, he lost the election as public dissatisfaction grew over the government's effort to increase revenue by raising electricity bills and imposing heavy new income taxes on professionals and businesses as part of the government's efforts to meet the IMF conditions.

Voters were also drawn by the NPP's cry for change in the political culture and an end to corruption, because they perceived the parties that ruled Sri Lanka so far caused the economic collapse.

Mr Dissanayake's promise to punish members of previous governments accused of corruption and to recover allegedly stolen assets also raised much hope among the people.

Jeewantha Balasuriya, a businessman from the town of Gampaha, said he hopes Mr Dissanayake and his party will use their resounding victory to rebuild the country.

"People have given them a strong mandate. I am hopeful that the NPP will use this mandate to uplift the country from the present pathetic situation," he said.

He expressed confidence that Mr Dissanayake and his party would curb corruption and mismanagement and establish law and order, which he said were vital for resuscitating the economy.
