Speaking to reporters in Jalgaon in north Maharashtra, Raut said Sena chief Uddhav Thackeray would take the final call in case Khadse wished to join the Sena.
"Nowadays, Khadse seems to have become closer to (NCP leader) Ajit Pawar and the latter too is responding to Khadse. This indicates Khadse will not remain with the BJP for long," Raut said.
Meanwhile, Leader of opposition in legislative council Dhananjay Munde of NCP alleged that the BJP came to power with the support of OBCs but is now doing "injustice" with them.
Speaking in Jalna, Munde said the BJP didn't do justice with former minister Eknath Khadse and late Gopinath Munde.

"The NCP is the only party who gave the rightful share to OBC community," he said.
Recalling that NCP chief Sharad Pawar was the "first leader to implement the recommendations of Mandal Commission," Munde said NCP leaders Sunil Tatkare, Jaydutt Kshirsagar, Ganesh Naik, Chhagan Bhujbal were OBC faces "who got an opportunity to serve people due to Pawar".
The BJP is merely doing a lip service, he alleged.
