Sri Lankan President Gotabaya Rajapaksa dissolved parliament late on Monday, and also the election commission declared a general election for April 25.
Rajapaksa – a former defense secretary – won the presidency last November and termed his own elder brother Mahinda Rajapaksa as interim Prime Minister.
The election might assist the Rajapaksas, famous for its savage defeat of separatist Tamil rebels, to strengthen their grip over the island of 22 million people.
The president is permitted by Sri Lanka’s constitution to dissolve parliament any time after it finishes four-and-a-half decades of its last-minute term – that it did on Monday.
The new parliament will meet on May 14, the election commission said in a statement.
