Jonathan Moi, eldest son of retired President Daniel Moi, has died in Nakuru, Press Secretary Lee Njiru has confirmed.
Njiru has said a detailed statement of Jonathan's death will be issued later.
His brother Baringo Senator Gideon Moi mourned Jonathan for his "daring exploits in the racing tracks, in muddy and dusty tracks, during this time of Easter".
"He was amiable, social and down - to - earth and industrious human being. We are distraught as family and we ask for your prayers and seek your understanding and indulgence to allow us mourn privately," said
"We will continue to inform Kenyans on need basis and further arrangements."
