"Party's central elections committee has cleared the names of Nirmala Bhuria and Gayatri Raja Puar," Madhya Pradesh BJP chief Nandkumar Chauhan said.
Nirmala Bhuria, a five-time MLA, is the daughter of late Ratlam MP and BJP's tribal face Dileep Singh Bhuria while Gayatri is the wife of the late BJP leader Tukojirao Puar, a former state minister.
The bypolls were necessitated by the death of Dileep Singh Bhuria and Tukojirao Puar.
The last date for filing nominations is November 4.
Congress is yet to announce its candidates. Party sources said that former Union Minister Kantilal Bhuria, who had contested from Ratlam unsuccessfully last time, may get the ticket again.
