Adam Namadi Sambo, a son of former Vice-President Namadi Sambo, has reportedly asked delegates to refund the N2 million each doled out to them before the election.
He is vying for the Peoples Democratic Party (PDP) primaries in Kaduna North Federal Constituency of the House of Representatives.
He had promised to add N1.5 million to the amount given to each of the delegates, secured the least votes among the three contenders.
Delegates across Nigeria reportedly collected millions of naira and hundreds of dollars from the aspirants who appeared in a hurry to outspend one another.
However, Samaila Suleiman, the incumbent defeated Shehu Usman ABG and Sambo.
Suleiman, who recently decamped from the ruling All Progressives Congress (APC) to the PDP, won with 22 votes against Shehu Usman ABG who polled 14 votes.
Delegates told Daily Trust that Suleiman had distributed between N3.5m and N4m to each delegate while ABG gave out N2.5m in cash and Namadi had distributed N2m to delegates.
However, having lost the contest, both ABG and Sambo demanded an immediate refund.
Suleiman, who is the Chairman, House Committee on Special Duties, left the APC following the interest of Governor Nasir el-Rufai’s eldest son in his seat at the green chamber.
