ODM leader Raila Odinga was on Tuesday taken ill after checking himself into the Karen Hospital for treatment.
Doctors at the health facility diagnosed Mr Odinga with food poisoning.
He was treated and discharged on Wednesday afternoon.
Oding’a spokesperson, Dennis Onyango, said he was recuperating well ahead of his flight to South Africa to visit his daughter, Rosemary Odinga.
“Mr Odinga was to close the Devolution Conference in Naivasha on Thursday, March 9, but he won’t attend. Instead, NASA co-principal Moses Wetangula will represent him,” Dennis Onyango told Citizen Digital.
“Mr Odinga will leave for South Africa tomorrow (Thursday, March 9) at midday to visit his ailing daughter, Rosemary Odinga,” added Mr Onyango.
Rosemary Odinga, the elder daughter of Opposition leader Raila Odinga, was on February 28 flown to South Africa for further check up after 11 days of hospitalization in Nairobi.
