Raila-Kalonzo are expected to hold a first joint rally at Mkuru Kwa Njenga in Nairobi, on Thursday.
This comes just one day after Kalonzo stated that he would make a huge political declaration in two days.
There has been an intense lobby to woe Kalonzo back to Azimio coalition after the fallout with Mr. Odinga after missing out on the running mate position.
And Raila-Kalonzo political rally may mark his return to the Azimio La Umoja One Kenya Alliance, two weeks after his exit.
Speaking at the burial of former diplomat Joseph Katithi in Kyawango village in Mwala, Machakos, on Wednesday, 1, June, Kalonzo promised to give political direction urging the Kamba community to bear with him and support his political move.
“I will give a political statement within two days’ time. That’s why I am requesting the Kamba community to support my political move,” Kalonzo said.
Dennis Onsarigo, press secretary, Raila Odinga campaign secretariat, in a media invite also indicated that Kalonzo will be officially returning to Azimio today at 11 am.
Azimio Coalition secretary General Junet Mohamed also announced that the coalition is set for the big rally.
“Azimio la Umoja one Kenya coalition party will address the nation tomorrow at 2 pm from Mukuru Kwa Njenga,” Junet tweeted.
