By Uditha Jayasinghe COLOMBO (Reuters) -Sri Lankan President Anura Kumara Dissanayake's coalition, the National People's Power (NPP), was set to win a majority in a snap general election, results from the Indian Ocean island's poll body showed on Friday.

Securing a parliamentary majority will be crucial for Dissanayake to implement his agenda fully, as executive power alone does not permit the appointment of a full cabinet or the passage of significant economic policies.

Sri Lankan President Anura Kumara Dissanayake’s leftist coalition is on track for a landslide victory in snap elections, delivering the Marxist-leaning leader a powerful mandate to ease punishing austerity measures in the crisis-stricken nation.
