Sri Lankan President Gotabaya Rajapaksa has declared victory in the country’s parliamentary election.

His brother Mahinda Rajapaksa is expected to be installed as prime minister, having held the role as caretaker since November.

The brothers’ party, Sri Lanka People’s Front, has secured a two-thirds “super majority” of seats needed to carry out its promised constitutional changes.

The party won 145 of the 225 seats, plus five more seats from its allies.

Mahinda Rajapaksa earlier tweeted that Indian Prime Minister Narendra Modi had called to congratulate him.
