The announcement was made by President Uhuru Kenyatta who sent a message of condolence to the Kibaki family.
The former First Lady has been in out of hospital for several months now, since going out of the public limelight before former President Mwai Kibaki got out of power in 2013 at the end of his second five year term.
Born in 1940, Lucy Kibaki was Kenya’s First Lady from 2002 to 2013.
She is survived by her husband Mwai Kibaki and four children Judy Wanjiku, Jimmy Kibaki, David Kagai, and Tony Githinji.
She will be remembered for her no-nonsense attitude, having been feared by State House staff, ministers and politicians when she was a tenant at the house on the hill.
Businessman Chris Kirubi has also sent a message of condolence to the Kibaki family.
“I would like to send my sympathy to former President Kibaki and his family at this time of sorrow. It is my prayer that the Almighty God gives them comfort.”
