During the prayer meeting, Raila demanded that the Kenya Kwanza government lowers the cost of basic commodities or face mass action within 14 days.
"We’ve talked about the rising cost of basic commodities like unga, electricity, fuel, sugar and milk among others for far too long. We have complained about rising taxes and talked about children dropping out of school for lack of fees," Raila said.
He also demanded that IEBC servers be opened, "failure to which, we shall lead the people to restore their authority and voice".
This is the first time the former Prime Minister is leading other opposition luminaries and a legion of supporters for a prayer rally in the city CBD.
He was accompanied by Narc leader Martha Karua, Wiper leader Kalonzo Musyoka, former defence CS Eugene Wamalwa, former Kakamega governor Wycliffe Oparanya, Roots party leader George Wajackoya among other leaders.
