Tanzania President John Magufuli has called for prisoners to be made to work long hours, and to be punished if they are lazy.
John Magufuli was speaking at the inauguration of a new prisons chief.
He also called for conjugal visits to be stopped.
“A man is in prison, leaving his wife outside, and a prison official receives this woman and authorises the prisoner to do things he is not supposed to do during his detention. I don’t want to hear talk of that anymore,” he said.
Magufuli said the underemployment of inmates led to drug use and homosexuality in jails.
“I don’t want to hear about this. I want reforms in the management of prisons,” he said.
The leader, whose nickname is The Bulldozer, has been accused by detractors of becoming increasingly authoritarian – a charge he denies.
