Uhuru Kenyatta is set to be sworn in as Kenya’s new president, following his victory in March against Raila Odinga.
His first-round victory was recently upheld by the Supreme Court.
Mr Kenyatta and his deputy, William Ruto, face charges at the International Criminal Court relating to post-election violence five years ago.
Sudanese President Omar al-Bashir, who faces an ICC arrest warrant over the conflict in Darfur, will not be in Nairobi for the inauguration.
Mr Kenyatta is the son of Kenya’s founding father, Uhuru Kenyatta, and is heir to one of the largest fortunes in Kenya.
He served as deputy prime minister, minister for trade, and finance minister under outgoing President Mwai Kibaki.
The 51-year-old will be Kenya’s youngest president.
According to official results, he beat Mr Odinga by 50.07% to 43.28% in March, avoiding a run-off by just 8,100 votes.
- Born October 1961, son of founding President Mzee Jomo Kenyatta
- Heir to one of the largest fortunes in Kenya, according to Forbes magazine
- Groomed by former President Daniel arap Moi to be his successor, but heavily lost 2002 election to Mwai Kibaki
- Second African president to be indicted by ICC, after Sudan’s Omar al-Bashir
Mr Odinga challenged the result, but said he would respect the Supreme Court ruling in Mr Kenyatta’s favour.
After the ruling, Mr Kenyatta said his government would “work with and serve all Kenyans without any discrimination whatsoever”.
“Above all, let us continue to pray for peace in our country,” he said.
The election was Kenya’s first after a disputed poll in 2007, which led to violence that left more than 1,200 people dead.
Mr Kenyatta is due to appear at the ICC for his trial in The Hague later this year, accused of crimes against humanity. He denies the charges.
Kenya is a party to the Rome Statute, the treaty which established the ICC in 2002.
But like most African countries, it has refused to enforce the ICC warrant for Mr Bashir’s arrest.
Earlier, Kenyan government spokesman Muthui Kariuki told the BBC that Mr Bashir had been invited and would not be arrested if he accepted the invitation.
After Mr Bashir visited Kenya in 2010, a Kenyan court ruled that the government must arrest him if he returned, in line with its international obligations under
The government is appealing against the ruling.
