William Ruto on Tuesday was sworn in as Kenya's fifth president to deafening cheers from thousands of supporters.
The crowd kept cheering whenever Ruto's name was mentioned.
Wearing a dark grey suit and yellow tie, the President while clutching a Bible as he took the oath of office pledged to "protect and uphold, the sovereignty, integrity and dignity of the people of Kenya".
"I do swear that I will be faithful and bear true allegiance to the Republic of Kenya," Ruto said.
Rigathi Gachagua also took the oath of office as Deputy President.
"I will always truly and diligently serve the people and the Republic of Kenya in the office of the deputy president. I will do justice to all without fear, favour, affection and ill will," he said.
Former President Uhuru Kenyatta handed over the Constitution to Ruto as part of the instruments of power.
Chief of Kenyan Defence Forces Robert Kibochi watched the handing over at Moi International Sports Centre, Kasarani, Nairobi.
Uhuru watched as his blue presidential standard was lowered on one pole while the presidential standard of the new commander was hoisted.
Immediately after receiving the instruments of power, KDF welcomed the new president with the ceremonial 21-gun salute.
The Constitution is handed over as a symbol that the country is governed by the rule of law, which is supposed to be the guide in the choices the President makes.
Ruto's first order as President and Commander-In-Chief of the Defence Forces was to command a break on the Guard of Honour that had been inspected by Uhuru before he handed over power.
The ceremonial sword, made of stainless steel handle and a gold-coated blade, which is traditionally kept at the office of the President in Harambee House, Nairobi, was handed over.
Uhuru on Monday held talks with his successor William Ruto and appealed to him to serve all Kenyans equally as he assumes office.
In his valedictory speech to the country — in which for the first time he congratulated Ruto on his victory — Uhuru wished the President-elect success in his service to Kenyans.
“Mr President-elect, as you walk the path to your inauguration and beyond, you will be President not just for those who voted for you but for all Kenyans,” Uhuru told Ruto.
