Sri Lankan Parliament Speaker Mahinda Yapa Abeywardena said President Gotabaya Rajapaksa has not yet sent him a letter of resignation.
Gotabaya Rajapaksa had previously announced that he would resign on July 13.
Rajapaksa, who fled the country yesterday after anti-government protests, is believed to be in the Maldives.
It was reported that the flight of the passenger plane that will take Rajapaksa to Singapore was delayed at midnight for security reasons.
In Sri Lanka, Prime Minister Ranil Wickremesinghe was appointed as the Interim President yesterday, and protesters reacting to this decision stormed the Prime Minister’s Office and occupied some government offices despite the declaration of a state of emergency.
The protesters agreed to withdraw from the government offices they occupied.
Hospital officials announced that one person died and at least 80 others were injured in yesterday’s protests.
Demonstrators say Wickremesinghe, who was appointed prime minister in May, also played a role in the economic crisis.

Wickremesinghe said, “We cannot tear up our constitution. We cannot allow fascists to come to power. We must end the fascist threat to our democracy.”
