Johannesburg, Mar 10 (IANS): Former wife of the late Nelson Mandela, Winnei Madikizela-Mandela was on Thursday admitted to a hospital for observation, a statement from her family said.
"Mandela went to the hospital for routine medical check up on Wednesday, March 8. A decision was taken to admit her for further observation," enca.com quoted the statement as saying.
Madikizela-Mandela, 80, was in hospital for several weeks last year for back surgery.
