Sri Lankan President Anura Kumara Dissanayake’s coalition won a historic parliamentary supermajority in the country’s election, underscoring the depth of the support for the leftist leader who pledges to combat corruption and change the terms of an unpopular International Monetary Fund bailout.

Anura Kumara Dissanayake’s National People’s Power Party won at least 123 of the 225 seats in parliament, according to partial results released by the Elections Commission.
