Jonathan Toroitich Moi will be buried on Saturday in Baringo County.
Toroitich, who was retired President Daniel Moi's eldest son, succumbed to cancer on April 20 while receiving treatment at Nakuru War Memorial Hospital.
President Uhuru Kenyatta and Opposition Chief Raila Odinga will not be in attendance as they are in China. But Deputy President William Ruto will attend the burial ceremony that begins at 10am at Kabarak University.
Kabarak University vice chancellor Henry Kiplagat, the burial committee chairman, on Friday said Toroitich will be laid to rest in his Kabimoi home in Baringo County.
"The main burial service will be held at Kabarak University. All mourners are invited to attend," he said at Kabimoi, Eldama Ravine. The body is lying at Lee Funeral Home.
Toroitich, who was popularly known as JT, was a celebrated rally driver. He has left behind a widow, Sylvia, and four children.
His sons Clint and Wayne thanked everyone who condoled with them. "It has been difficult for us after we lost our father, but we appreciate the immense support we have received so far from friends, neighbours and leaders," Clint said.
Those who visited the family on Friday at Kabimoi include businessman Jackson Kibor and governors led by Kakamega's Wycliffe Oparanya.
