Voting in Kitui West by-election kicked off at 6am Monday amid low voter turnout attributed to a heavy downpour Sunday night.
By 7am, only a few people had turned up in most polling centres with the number of those who had voted ranging between five and 10.
Most candidates had, however, cast their votes by midday.
Wiper party candidate Edith Nyenze cast her vote at Kyondoni Primary School at 9.30am, while Mutiso Leli of Narc-Kenya voted at 8am at Matinyani AIC Day Secondary School.
Dr Fridah Mutui of Kenya Social Congress cast her vote at 8.30am at Kikanga Primary School.
