ODM leader Raila Odinga is expected to address a rally at Kamukunji grounds in Kibra from 2 pm.
Raila had earlier said it will be a day of prayers for peace in Kenya, though politics is expected to dominate.
The former Prime Minister has been spearheading BBI campaigns recently in Kilifi, Mombasa and Sambur.
His visit to Kamukunji comes a day after Siaya Senator James Orengo warned “politicking” civil servants to keep off politics.
“There is a cabal of civil servants inside the government who have already decided who will rule Kenya in 2022. We are going to expose them,” said Senator Orengo
ODM politicians among them George Aladwa, Nairobi Women rep Esther Passaris, MP Babu Owino, and former MP Reuben Ndolo had earlier this morning accompanied Raila to Woodley PAG Church.
