Philippine President Rodrigo Duterte does not have cancer, an official said on Tuesday, after the 73-year-old leader missed two official evets last week and underwent a series of tests for the disease, Al-Jazeera reports. The controversial leader, who’s presiding over a deadly war on drugs that has killed thousands since he took office in June 2016, has long complained of suffering from Barrett’s oesophagus – an inflammation of the tube connecting the mouth to the stomach – from alcohol use when he was younger, according to The ASEAN Post. In the event of Duterte resigning over illness, among those positioning themselves for leadership include Vice President Leni Robredo and former senator Ferdinand Marcos, writes Raissa Robbles for South China Morning Post.
