Wife of the President, Aisha Buhari on Sunday condemned the irregularities that marred the primaries of the ruling All Progressives Party (APC), across the nation, taking a swipe at the party's National Chairman Comrade Adams Oshiomole under whose watch the primaries were conducted.
Abubakar, 71, won 1,532 votes, trouncing his main rival Aminu Tambuwal, the governor of northern Sokoto state who scored 693 votes at the party's convention in the southeastern oil hub of Port Harcourt.
He has long enjoyed support from the business elite in Nigeria's commercial capital Lagos for his conservative-capitalist ideals and, as vice president in a PDP administration from 1999-2007, implemented a programme of liberalisation in areas including the telecoms sector.
The meeting with Buhari was attended by Eight Governors and lasted for over an hour.
"We are expecting a very good convention, we are working very hard to deliver a process that is credible, free, fair and acceptable", he said.
Ifeanyi Okowa, Governor of Delta State and Chairman, PDP National Convention Planning Committee declared former vice president Atiku Abubakar victor and Presidential candidate of PDP after he polled 1532.
"The event in Port Harcourt between yesterday and today was a victory for Nigeria and for democracy".
The governor who spoke during a visit to the Lagos State PDP Secretariat, told party members that the country is highly complex to be managed by politician who is not well grounded on developments in the country.
Some Nigerians have however criticised the choice of candidates by saying none of those mentioned deserves to fly the party's flag at the presidential race.
Dubbed "Baba Go Slow" because he took six months to appoint Cabinet ministers, he has also faced attacks for his handling of the economy, which plunged into recession in 2016.
They will be deciding who shall represent the party ahead of the presidential election in February 2019.
