The New Patriotic Party says the Electoral Commission will be engaging in an illegality if it uses the old voters register to organize two impending bye-elections.The EC in accordance with Article 112 of the constitution announced the dates for the two bye elections in Wulensi and Kwabre West following the deaths of two MPs.But the NPP is challenging the EC to state which register it will be using to conduct the bye-elections.The chairman of Electoral Affairs of the NPP Mathew Opoku Prempeh said it will be an act of illegality if the old register is used.He told Joy News’ Beatrice Adu, the old register has been outlawed following a legislation passed in March 25, insisting the NPP will not be part of any illegality if it is the intention of the EC to use the old register.Opoku Prempeh said the EC must use the new biometric voters register and a verification system to organize the two bye-elections.“My party has already taken a position. The EC should come out and tell Ghanaians what register they are going to use for both the Wulensi and Kwabre West constituencies.“If the EC cannot guarantee the biometric register which is the only legal document we can use to vote in a public election then I am afraid the EC cannot dabble in illegality.“…There is nothing like an old register in the system. That has been completely cancelled by a law from the Parliament of Ghana.“That is why I am surprised the EC continues to deceive Ghanaians there is something called the old register. That register has been cancelled as far back as March 25, 2012.Asked if the party will take part in the bye-elections, Opoku Prempeh said the NPP is a party that respects the rule of law hinting no party worth its salt to be part of such an illegal election.
