Atiku said PDP would be strengthened to take over power from the All Progressives Congress, APC, in 2023.
He made the declaration during his visit to the Edo State Governor, Godwin Obaseki, at the Government House in Benin on Tuesday.
On his part, Obaseki commended Atiku for his leadership and support during the last election in the state.
He said: “I cannot thank you enough for the leadership that you continue to provide; the counsel you gave me during my electioneering, the private conversations, and the assistance you rendered to me when we joined the party.
“We had challenges, but you stepped up and threw your weight behind the resolution of the issues.”
