Former President John Mahama has challenged his successor Nana Akufo-Addo to rise above propaganda and implement his juicy promises he made to Ghanaians.

Speaking after a unity walk by National Democratic Congress members in Tamale, the former president, who has been accused of using the walk to launch his presidential bid, said Ghanaians are suffering.

And that no amount of propaganda by the president will make the people forget about their economic situation which in his view is worsening.

“No amount of propaganda can make the people oblivious of their own responsibilities because they are living with the prevailing circumstances,” he said.

Prior to the walk, a pro-NDC group, the Action Movement, had warned him that he has no mandate to organise the unity walk.

But the former president used the walk to appeal to NDC supporters to eschew division and work together.

He said the party must provide effective opposition and also represent the voice of the voiceless.
