Lawrence Nginyo Kariuki, a veteran politician and a champion for multiparty democracy, has passed on at the Aga Khan University Hospital, the family has announced.
Mr Kariuki, who was also a businessman, had been ailing for some time until his death in the wee hours of Monday morning.
He was also the founding member of The National Alliance (TNA), a political party that was at the helm of power between 2013 and 2017.
The family and hospital remained tight-lipped about what was ailing the former politician, but he looked frail in his last public appearances such as in late 2018 when opposition leader Raila Odinga paid him a visit at his home in Kiambu.
Politicians took to social media to mourn the death of the veteran politician.
