A former Director General of the Ghana Broadcasting Corporation, William Ampem-Darko, is questioning the paternity of outspoken politician, Dr Sekou Nkrumah – a son of Ghana’s first president, Dr Kwame Nkrumah.

Ampem-Darko appears overwhelmed with certain comments made by the son of the respected pan-Africanist, adding a DNA test will help “prove if Sekou is truly Kwame Nkrumah’s son.”

The former GBC boss’ assertions come on the heels of Dr Nkrumah’s recent concerns about the age and health of two-time flagbearer of the New Patriotic Party, Nana Akufo-Addo.

Dr Nkrumah, who supported the former cabinet minister and legislator, revived the age debate Tuesday when he said: “The age thing cannot be swept under the carpet. Age is becoming a problem for Nana Addo.”

According to the third son of Dr Nkrumah, the NPP must consider going to the 2016 elections with another candidate instead of the former foreign affairs minister.

But the comment appears to have angered the ex-GBC head who once contested as parliamentary candidate for the main opposition party.

He wrote on his Facebook wall: “There should be DNA test to prove if Sekou is truly Kwame Nkrumah's son.”

Akufo-Addo himself has told party supporters that he is fit to contest the presidency.
