Coalition for Reforms and Democracy leaders now want the national voter registration which kicked off on Monday to be extended to 60 days from the 30 days schedule.
The leaders said the 30 days set for the exercise were not enough to register approximately nine million Kenyans eligible to vote.
Speaking in Kisumu where they witnessed the launch of the exercise at Kenyatta Sports Ground, the leaders, Raila Odinga, Kalonzo Musyoka and Moses Wetangula said the exercise is critical and should be treated with the seriousness it deserves.
"I want to appeal to the Parliament to allocate more funds to IEBC as they will be approving the supplementary budget so as to avoid excuses that lack of funds kept off people from the exercise," said Raila.
"There were at least four million people who failed to participate in the 2013 general election because they had no voting cards. Five years later we believe more people have attained the voting age hence there will be a big number of people turning up for the exercise," said Kalonzo.
The leaders also took issue with the commission over what they termed imbalance in the distribution of voter registration kits. They questioned the criteria used by IEBC to allocate the kits, saying such imbalance amounted to rigging before the real election.
"Some counties like Malindi and Mombasa have a very big number of potential voters but have got the least kits while some Counties with few voters got so many votes. The cretaria used by the commission to allocate the machines have to be reviewed," said Raila.
Wetangula urged the national administration which include chiefs and DOs to release the IDs in their custody so as to enable people register in time.
"I take this opportunity to urge Kenyans of good will, patriotic and of good thinking to come out and register so that they have a chance to elect their preferred government come 2017," he said.
The leaders who were accompanied by governors Jack Ranguma (Kisumu), Cyprian Awiti (Homa Bay) and Wickliffe Oparanya (Kakamega), Siaya Senator James Orengo among other leaders vowed to rally Kenyans to register so as to be able to give them victory in 2017.
