Vice-President Yemi Osinbajo is currently meeting with members of the new Peoples Democratic Party (PDP).
The meeting is holding at Akinola Aguda House, the official residence of Osinbajo in the presidential villa, Abuja.
Lawal Shuaibu, deputy chairman of the All Progressives Congress (APC), and Abubakar Malami, attorney-general of the federation (AGF), are present at the meeting.
The nPDP members in attendance are Senate President Bukola Saraki, Yakubu Dogara, speaker of the house of representatives; Abdulfatai Ahmed, Kwara governor; and Rabiu Kwakwanso, former Kano governor.
Others are senators Barnabas Gemade, Danjuma Goje, former Adamawa Governor Murtala Nyako and some members of the house.
