Kenyan police fired tear gas and arrested several senior opposition politicians as hundreds protested against President William Ruto.
The event, held at the Kasarani Stadium, is Kenya’s fifth presidential inauguration.
Mr Osinbajo on Tuesday departed for Nairobi to represent Nigeria at the inauguration of William Ruto as the fifth president of Kenya.
He said the PDP had finally convinced Nigerians that they were not prepared or interested in building a harmonious, united and progressive country.
The impact of the ICC in Kenya will be a matter of considerable speculation well into the foreseeable future.
Kenya’s Supreme Court has maintained that Ruto emerged victorious at last month’s presidential election, dismissing Odinga’s allegations
Opposition leader Raila Odinga, seeking the presidency for the fifth time, is contesting the result that declared Deputy President William Ruto the winner.
One of the ironies of politics is how easily fiction becomes reality.
In 2017, the Supreme Court overturned the election result and ordered a rerun, which Mr Odinga boycotted, saying he had no faith in the election commission.
Mr Ruto’s victory sparked violent protests in some parts of the country Monday, with demonstrators alleging there were irregularities during the tallying of the votes.
