Wiper leader Kalonzo Musyoka has dropped his presidential bid in favour of ODM leader Raila Odinga.
Speaking on Saturday at KICC, President Uhuru Kenyatta said Kalonzo had put aside his ambitions and will now support Raila.
"There are those who are more abled like Kalonzo. But he has put his ambitions aside. Let us all clap for him. We thank him," he said.
Uhuru also exhumed confidence in the former Prime Minister's ability to develop the country and fight corruption.
"I have no doubt that he has the ability and God will help him in ensuring our country develops and moves forward in unity and fighting corruption."
Uhuru said he was confident that Raila will not forget other leaders once he becomes president.
"We will hear of Kalonzo Musyoka, Gideon (Moi), Ngilu (Charity) and other leaders. We will hear representation of all who are here because that is the only way to succeed," he said.
ODM leader who also spoke at KICC admitted that they had unresolved issues with Kalonzo, but that was now a thing of the past.
He added that they have decided to work together, ahead of the August 9 polls.
"Kalonzo and I had some problems but we have discussed and shook hands. We have decided we will walk together."
He also insisted that he is not anybody's project, as widely claimed by his opponents.
"I am not Uhuru's project and he is not my project," Raila said.
Earlier, the coronation of ODM leader Raila Odinga as the presidential candidate of Azimio la Umoja was delayed after Wiper boss Kalonzo Musyoka allegedly issued fresh demands before joining the formation.
The event was scheduled to start at 9 am but five hours later, nothing had commenced.
Sources said the Wiper leader had insisted on a running mate position for him to join the formation.
This position, however, has been reserved for the Mt Kenya region.
