Communications Director of the opposition New Patriotic Party (NPP), Nana Akomea, has drop hints that his party will still challenge the results of last December election despite the investiture of President John Dramani Mahama.

Speaking on Joy FM in Accra on Monday, Nana Akomea brushed aside suggestions that the presence of the NPP at the ceremony would have enhanced consensus building between the two main political parties.

“The NPP showing up at the ceremony wouldn’t have made any difference. We all witnessed what transpired in parliament this morning, and I think that was enough to show that the two parties were not [fighting] if people are talking about consensus building,” Nana Akomea added.

President John Dramani Mahama was earlier in the day sworn in by the Chief Justice, Georgina Theodora Wood, as President of the Republic of Ghana and became the sixth President under the Fourth Republic.

Official results of the election gave President Mahama 50.7% of the vote, enough to avoid a run-off against the NPP's Nana Akufo-Addo, who won 47.7%.

The NPP after the declaration by the Electoral Commission (EC) rejected the results, claiming the elections were rigged in favour of President Mahama and indicated its resolve to challenge the results at the highest court of the land, the Supreme Court.

Leaders of the party insisted there was ample evidence of widespread irregularities, which favoured the president and the National Democratic Congress (NDC).
