Singh is serving a life sentence for murdering Gopalganj district magistrate G Krishnaiah in 1994.
Yadav, a sitting MP, who is seeking re-election from Madhepura parliamentary constituency in the flood prone Kosi region, visited Panchchgachia and met Singh’s mother Gita Devi.
Yadav told media persons that he is related to Singh’s wife Lovely Anand, a former MP.
Yadav even claimed that it was he who asked Samajwadi Party chief Mulayam Singh Yadav to field Singh’s wife Lovely Anand from Sheohar Lok Sabha seat.
It is said that Singh has a strong hold over his castemen-Rajput, who have sizeable vote share in Madhepura. "Yadav visited Singh's village to send a message that his family’s blessings are with him," a JD-U leader said.
Yadav is contesting against RJD candidate Pappu Yadav, a controversial former MP.
