Former president John Mahama says no politically engineered voters' register can save the governing NPP government from being voted out from power.

His comment comes on the heels of the Supreme Court judgement allowing the Electoral Commission to compile a new voters' register excluding the use of current voters' ID cards and birth certificate as breeder documents.

A private citizen, Mark Takyi-Banson and the opposition NDC filed the case in court asking that it stops the EC from compiling the register or allow the use of the birth certificate and voters ID card by prospective voters as proof of identification.

But the Apex Court in a unanimous decision on Thursday ruled that the Commission has the power to compile a new voters' register.

While expressing disappointment in the court's ruling, Mr Mahama said he is optimistic Ghanaians will vote out the Akufo-Addo government even with a new electoral roll.

"No politically engineered register can save this governing government from the judgement of the people; from the inevitable defeat that awaits them in the next 165 days. With or without the new voters' register the NDC shall win the election by the grace of God," he said.

The NDC flagbearer accused NPP of consistently putting in place measures that will disenfranchise eligible voters.

"We have been very clear in our minds that the decision to compile a new voters register was in pursuit of this long-held agenda, hence our efforts to stop the wholesale attempt to exclude vast sections of our population from the process to determine who leads them," Mr Mahama said.

He also said the EC has allowed itself to be manipulated by government in achieving its parochial interest.

"It is deeply regrettable that the Electoral Commission, which should be independent, has made itself a willing tool in the execution of this most diabolic agenda," Mr Mahama revealed.

The former president, however, urged Ghanaians of voting age to channel their disappointment at the effort to exclude them from the electoral process into an opportunity to have their voices heard.

He said they should turn up in their numbers to register when the process begins.
