Gotabaya Rajapaksa has resigned as President of Sri Lanka, after fleeing to Singapore in the face of mass protests at home over his rule.

He is believed to have wanted to leave Sri Lanka before stepping down, in order to avoid the possibility of arrest, under a new administration.

The cost of food, fuel and other basic supplies have soared for Sri Lankans.

In the capital, Colombo, delighted demonstrators, greeted news of the President's departure with dancing.

The resignation letter was sent by email to the Speaker of Parliament, who said he would complete legal processes, and announce it officially on Friday.
