Jubilee aspirants in Uasin Gishu, Nandi, Elgeyo-Marakwet and Baringo counties have vowed not to participate in the nominations until enough ballot papers are provided.
The aspirants held a crisis meeting on Friday to deliberate on the way forward after large-scale anomalies were reported.
In Uasin Gishu, Governor Jackson Mandago, MPs Alfred Keter (Nandi Hills) and Oscar Sudi (Kapseret) led hundreds of supporters through Eldoret town denouncing ill preparations for the nominations.
They had earlier held a crisis meeting at the Eldoret Sports Club, where they agreed not to participate in the voting until enough ballot papers are guaranteed.
“We had been assured of enough ballot papers by the national and county election board. But we have very few ballot papers in various polling stations… this will deny voters chance to elect the leaders they want,” said Mr Keter.
Others who attended the charged meeting included MPs James Bett (Kesses), Silas Tiren (Moiben), Edwin Barchilei (Soy) and Eusilah Ngeny’ (Uasin Gishu woman representative).
“What we are asking is that they postpone the exercise until ... they have enough materials. They will decide on the date,” said Mr Mandago.
He cited a polling station in Langas where a mere 1,000 ballot papers were delivered against 11,000 registered voters.
Mr Mandago and Mr Keter said they had mobilised residents in the region to register in large numbers and wondered why the register had not been updated.
“They are using a register used in 2013 yet we [registered more] residents. In Uasin Gishu, 106,000 new voters were registered - we demand the register to be updated,” said Mr Mandago.
Mr Keter alleged that there was a plot to rig party primaries in favour of certain aspirants.
“Recently, we said there was a plan to influence the outcome of the primaries. We demand that the president and his deputy crack the whip on some individuals giving the party a bad name,” said Mr Keter.
A spot check by the Nation at many polling stations revealed that voters trooped in from as early as 5am but were disappointed on learning that there were not enough voting materials.
“We’ve been here for two hours but nothing is going on. We suspect foul play in all this,” said Stephen Mulinya at the MV Patel Memorial Hall polling station.
At the Race Course and Wareng High School polling centres, some of the residents who had turned up to vote were forced to go back home.
“We came around 6.20am but we are disappointed that there was no voting. We had sacrificed to come to vote,” said Judith Kipande, a distraught resident.
Cases of candidates' names missing were also reported at some polling stations in the region.
