Opposition leader Raila Odinga has vowed to reveal what transpired during the August 9 general election.
Raila said they have gathered sufficient evidence as well conducted a thorough research and probe on what saw President William Ruto declared winner.
"We know what they did, how they did it, and who helped them do it. We shall reveal all that on Wednesday at Kamukunji grounds," he said.
The ODM leader made the remarks while addressing his supporters at Utawala in Nairobi.
He said the rally will proceed as planned. Raila at the same time accused Ruto of firing the principal secretaries allegedly to create room to hire his 'own' people.
The PSs, he said, are civil servants and regardless of the administration that forms government, they should not be sent home.
"Principal secretaries are civil servants na ambao haitakikani ati serikali ikibadilika wanafutwa kazi," he said.
"Amefuta principal secretaries karibu wote, halafu yeye analeta ubaguzi. Hawa watu wote ameleta ni kabila yake."
This loosely translates to he has sacked almost all principal secretaries and replaced them with his tribesmen.
