On Sunday, Azimio leaders led by Raila Odinga attended a church service in Donholm ahead of their planned mega rally.
The leaders included Narc Kenya leader Martha Karua, Kalonzo Musyoka, Eugene Wamalwa, and former Kakamega governor Wycliffe Oparanya.
Embakasi East MP Babu Owino who is their host was also present.
The leaders fellowshipped at Jesus Teaching Ministries church.
"Earlier today, we joined the congregation of Jesus Teaching Ministry (JTM) Church in Donholm Nairobi and fellowshipped together. @RailaOdinga @skmusyoka @GovWOparanya @EugeneLWamalwa @HEBabuOwino," Martha Karua tweeted.
During the rally, Raila is expected to give "directions" to his supporters over what he claims to be evidence of how he was rigged out in the August 2022 general election.
He claims a whistleblower who works with the IEBC had provided them with proof of how he was rigged out.
In the evidence, he claims to have won by over 8 million votes while Ruto had 5.9 million votes.
