Former First Lady Lucy Kibaki died at a London hospital on Tuesday morning after being unwell for about a month.
Lucy, who was the wife of former president Mwai Kibaki, died aged 76 at Bupa Cromwell Hospital.
The former First Lady fell ill in March and was admitted at the Nairobi Hospital’s Intensive Care Unit.
Lucy had earlier been taken to Gertrude’s Children’s Hospital for emergency care. Her family said she was suffering from age-related complications.
She was flown out of the country over the weekend for further treatment.
In a condolence message on Tuesday, President Uhuru Kenyatta said she will be remembered for her immense contributions to the country’s development.
