Supporters surround Kenya's main political opposition, National Super Alliance (NASA) presidential flag-bearer, Raila Odinga arriving on motorcade to a political rally on September 17, 2017 in the Nairobi suburb of Soweto.

Opposition leader Raila Odinga has vowed to boycott the poll if a list of demands are not met and launched on September 17 a nationwide campaign "against any election" run by the current electoral commission (IEBC), which he accuses of rigging the first poll.
