"Shatrughan Sinha and Ramkishore Singh's remarks have made it amply clear that a larger section within the BJP does not accept Narendra Modi as party leader," Bihar Congress media in-charge Prem Chand Mishra said in a statement here.
"When people within BJP are not accepting Modi, how come the citizens of the country will accept him?" Mishra asked.
The voices against the party indicates "possibility of the BJP breaking", he said.
Ramkishore Singh expressed doubt over leadership quality of Modi and praised Nitish Kumar, claiming at least 35 BJP MLAs won the last Assembly polls due to him.
