"I will contest from Patliputra," Yadav, who was a close confidant of Prasad and had resigned from all party posts on Saturday after denial of ticket from the seat, told reporters on arrival from Delhi here.
The Rajya Sabha MP, however, did not elaborate whether he would enter the fray as a nominee of any political party or as an Independent.
He said he would announce his decision in a day or two.
Yadav was denied a ticket from RJD following which he quit the party
There is speculation that both the ruling JD(U) and BJP ae in touch with the sulking RJD leader, who had lashed out at RJD at the selection of Misa Bharti from Patliputra and had spurned her attempt at rapprochement.
Chief Minister Nitish Kumar is reported to have himself talked to Yadav. JD(U) Bihar President Basistha Narayan Singh said that if Yadav, a popular leader known for his integrity and hard work, decided to join his party he was welcome.
There were also reports of Yadav being in touch with several BJP leaders.
