Jubilee Party Aspirants Forum has asked the party to expel politicians allegedly involved in bribing party employees.
Forum secretary Duncan Mathenge said the party must deal with corruption within its ranks by kicking out aspirants involved in the scandal.
"It is not right for the party to claim elections will be free and fair yet they are allowing corrupt politicians implicated in bribing party officials to receive extra ballot papers to remain on the ballot box," Mr Mathenge said.
He said party security officers had failed to maintain order.
