Ekweremadu, who represents Enugu West Senatorial zone, made the declaration on Tuesday morning.
The Enugu West lawmaker said he was persuaded by his people to return to the upper legislative chambers.
His words: “My people, the good people of Enugu West Senatorial District, including the Enugu West Peoples Assembly, Members of the National Assembly, Council Chairmen, members of the Enugu State Executive Council, Enugu State Chapter of Ohanaeze Ndigbo, leaders of the PDP from Enugu West, among others gave me a surprise on Sunday.
“They presented to me the PDP nomination form for the Senate, which they purchased for me, requesting that I return to the Senate in 2019.
“My people, my primary employers have spoken. I have no choice than to humbly accept to run for the Senate again”, he said.
