Colombo was rocked by another wave of mass protests on Saturday. Crowds tore through the barricades surrounding the presidential residence, climbed over the fence and took control of the area. Sri Lankan President Gotabaya Rajapaksa was reportedly evacuated. He is expected to resign on July 13, according to Sri Lankan newspaper Adaderana.
Parliamentary Speaker Mahinda Yapa Abeywardana has informed Rajapaksa of the decisions made at a Saturday emergency meeting of the party leaders, which was convened in response to the mass protests in Colombo. The letter called for the immediate resignation of Rajapaksa and Wickremesinghe and provided for convening the parliament within seven days to appoint an acting president.
