UNP sources say ousted Prime Minister Ranil Wickremesinghe will be reappointed Prime Minister on Sunday. 

This follows a telephone conversation between President Maithripala Sirisena and Ranil Wickremesinghe that took place a short while ago. 

Former President Mahinda Rajapaksa, who was appointed Prime Minister in a surprise move seven weeks ago, triggering the political crisis in Sri Lanka, has said that he will step down from the position. 

He is expected to officially resign tomorrow while making a special address to the nation.
