The Orange Democratic Movement (ODM) party has cancelled nominations for parliamentary seats in Kisii County.
Aspirants were called to the ODM headquarters on Wednesday night.
Some of them told the Nation that they had not received any communication from the party and therefore did not travel.
"We are not holding the parliamentary nominations. The aspirants are already in Nairobi. The party has seen it wise to use consensus for the positions,” said Kisii County ODM Chairman Kerosi Ondieki.
The cancellation of parliamentary nominations caught some aspirants off guard, with a few claiming that it was a scheme by the party to hand direct tickets to preferred names.
"We will not allow this. We thought ODM will this time round be democratic. But what has happened today is unacceptable. Our supporters were at polling stations by 6am ready to cast their votes," said Mr Laban Chweya, who is eyeing the Nyaribari Masaba seat.
Mr Chweya accused the party of open discrimination, saying it is repeating the mistakes it had committed over the years that led to its failure to win even a single MP seat in Kisii.
He said aspirants who travelled to Nairobi had betrayed the people, democracy and the common good.
Complaints also marred nominations for ward seats, with most supporters not sure which wards were to conduct primaries.
Polling materials also left the tallying centre at KIHBT late, with transport and fuel challenges affecting the distribution of materials.
In Bomachoge Borabu constituency, presiding officers protested their redeployment to neighbouring constituencies.
"We are being told to go to South Mugirango, yet we come from Bomachoge. We are unsure of our security there," said Mr Alex Aika.
Mr James Nyamasege said that they were not familiar with the terrain in neighbouring constituencies and criticised the party for lack of organisation.
