Mugabe in Singapore Again For Medical Reasons Amid ConcernsZimbabwe's President Robert Mugabe is still in Singapore for medical reasons, prompting opposition figures to question whether the 93-year-old still has the stamina to run the country.\n\nState media, quoting an information ministry statement, says the world's oldest head of state who left Friday for "a routine medical check-up" will be back later this week. This is Mugabe's third Singapore visit this year.\n\nMugabe had been scheduled to address a campaign rally on Friday, but organizers say that has been cancelled due to the trip.\n\nThe opposition, which has called him a "non-resident president" due to his frequent foreign travels, has expressed concern over his health, saying he should retire.\n\nMugabe has said he will contest next year's election, claiming he is still fit. He has been in power since 1980.
