A main opposition party in Tanzania has urged the government to “fully explain the mystery surrounding” President John Magufuli’s nearly three-week absence, saying the public has the right to know about his whereabouts and who is running the country. Al Jazeera reports that a vocal COVID-19 sceptic, Magufuli last appeared in public on February 27 and in recent days, speculation has been rife that the 61-year-old is ill with the coronavirus – though the prime minister said last week the president was healthy and hard at work. The party also called for the “unconditional” release of several people arrested in the country since last week for allegedly spreading false information about the sickness of political leaders.
