Orange Democratic Movement (ODM) leader Raila Odinga is on Sunday expected to make another tour of Kibra constituency as the November 7 mini polls draw nearer.
Raila's party is represented by Imran Okoth in the much-awaited race to fill the vacancy that was left after the death of immediate former lawmaker Ken Okoth.
Raila is expected to campaign alongside Imran with a mega rally set for Laini Saba grounds, beginning 2 pm.
In a poster on Party Director of Communication Philip Etale's Twitter handle, the former Prime Minister will be the chief guest in the function.
In the recent past, ODM has been on the door to door campaigns as opposed to holding rallies.
The party is, however, facing great competition from the ruling Jubilee Party, whose flag is being flown by retired footballer McDonald Mariga.
Also in the race is former Raila ally Eliud Owalo, who has since crossed over to the Amani National Congress (ANC), on whose ticket he is seeking the seat.
