Quami Ekta Dal's Ansari, a gangster-turned-politician and four-time MLA from Mau, is currently lodged in Agra jail in the BJP MLA Krishnanand Rai murder case.
"A decision in this regard has been taken at the meeting of Quami Ekta Dal," Mukhtar's brother Afzal Ansari told PTI today.
The step has been taken "to strengthen secular forces and avoid division of votes", he added.
Mukhter, who contested the last Lok Sabha polls on a BSP ticket, lost by a slender margin of 17,000 votes to Joshi.
Later, he was expelled from BSP and formed the Quami Ekta Dal in 2010.
