Former Nigerian vice president, Atiku Abubakar, has been elected the presidential candidate of the county’s main opposition party, the Peoples Democratic Party (PDP).
Mr Abubakar, a retired Customs officer was vice President between 1999 and 2007 under President Olusegun Obasanjo.
He would be challenging President Muhammadu Buhari of the ruling All Progressives Congress (APC) in the presidential election in February.
Mr Abubakar defeated 11 aspirants at a PDP national convention in Port Harcourt, Rivers State, held on Saturday and Sunday.
Other aspirants included the President of the Senate, Bukola Saraki, and the Governor of Sokoto, Aminu Tambuwal.
Abubakar, a chronic presidential candidate who has been vying for the presidency since 1992, scored 1,532 votes to beat all others.
His closest rival, Governor Tambuwal, scored 693 votes while Senate President Saraki came third with 317 votes, according to reports in multiple Nigerian outlets.
On Saturday, the ruling All Progressives Congress confirmed President Buhari at its own convention in Abuja. It was a non competitive convention and Mr Buhari was easily chosen.
Mr Abubakar dumped APC for the PDP last year and in series of interviews and statements has said that President Buhari has failed Nigerians in virtually all areas from security to the economy.
He has said that Mr Buhari has crumbled the economy and left Nigeria more divided than united. Millions have lost their jobs under him and the country should not afford four more years with him as President, Atiku has been preaching.
