The senior pastor of the Jesus House for All Nations Parish in Brent Cross, London, made the error during church service.
Introducing Obi, Irukwu said: “And we have the president, ah, the presidential candidate of the Labour Party, Mr Peter Obi.
“We always appreciate Mr Peter Obi. God will appreciate him, we appreciate him.”
In spite of their leader’s slip of the tongue, the congregation erupted in cheers and many church members got up for an ovation, as reported by Daily Post Nigeria
The former Anambra governor, who remained seated, joined the pastor and hundreds of worshippers in laughter over the error.
Obi is in court to challenge the outcome of the February 25 presidential election won by the candidate of the All Progressives Congress, APC, Bola Tinubu.
