Sri Lankan President Gotabaya Rajapaksa's government on Tuesday faced more trouble after the newly-appointed Finance Minister Ali Sabry resigned and dozens of lawmakers walked out of the ruling coalition amid nationwide protests over the country's worst economic crisis. President Rajapaksa had appointed Sabry after sacking his brother Basil Rajapaksa, who was at the centre of anger within the ruling Sri Lanka Podujana Peramuna (SLPP) coalition. In a letter to the President, Sabri said that he took up the job as part of a temporary measure. "However, after much reflection and deliberation and taking into consideration the current situation, I am now of the view for Your Excellency to make suitable interim arrangement to navigate the unprecedented crisis fresh and proactive, and unconventional steps needs to be taken including the appointment of a new finance minister,” Sabry said in the letter. He was among the four new ministers appointed by the President who dissolved his cabinet on Monday and sought to form a unity government.
