Ali Modu Sheriff, factional chairman of the Peoples Democratic Party (PDP), has nullified the party’s congress in Plateau state.

Sheriff also dismissed the claim of the Ahmed Makarfi-led caretaker committee that he is working for the APC.

Reacting to this claim at a press conference, he said: “Makarfi should shut up”, threatening to expose the committee chairman, and Ben Obi, its national secretary.

At the meeting with the Plateau delegation, which pledged support for him, the factional leader of the opposition party said he would soon inaugurate a committee that will organise a fresh congress in the state.

Bitrus Kaze, a former member of the house of representatives, who led the pro-Sheriff group, alleged that the process through which the current executive officials in the state emerged was not credible.

At the press briefing, Sheriff alleged that Makarfi and Obi have been paying secret visits to an APC chieftain.

He challenged them to dare him and see how he would allegedly expose them.

“If there are people in the PDP working for the APC, it’s Makarfi and Obi. Makarfi should not force me to reveal details that I should not reveal under normal circumstances,” he said.

“Makarfi and Obi have gone to visit one APC chieftain in his house twice and this particular individual is still in the APC. It would have been better if the man had left the APC to join the PDP.

“They are reserving the 2019 presidential ticket of the PDP for this individual who has been funding their activities. If Makarfi continues to attack my person, I will be forced to reveal further details of their alliance. So, Makarfi should just shut up.”
