Nobel Peace Prize winner Archbishop Desmond Tutu has announced he is withdrawing from public life.
The former archbishop of Cape Town was a leading campaigner against the apartheid regime in South Africa and has continued to fight injustice across the world.
After his 79th birthday in October, he said, he would reduce his workload to one day a week before retiring.
That work would be devoted to The Elders, a group appointed by former President Nelson Mandela to tackle the world's most pressing problems.
During the 27 years that Mr Mandela was in prison, Archbishop Tutu spoke out against apartheid - and won the Nobel peace prize in 1984 for his efforts, the BBC reports.
He was chosen by Mr Mandela to chair South Africa's Truth and Reconciliation Commission and investigate the crimes committed by all sides during the apartheid regime.
