"Manvendra Singh, who is campaigning against official candidate of the party Sona Ram from Barmer Lok Sabha seat should first leave or quit the party on moral grounds as it attracts his anti-party activities and gross disciplinary action soon," state BJP vice president Onkar Singh Lakhawat told reporters here.
Manvendra, who is son of expelled BJP leader and independent candidate from Barmer LS seat Jaswant Singh, has been attending his father's meeting against the party's official candidate.
"Manvendra is virtually violating the party's guidelines and principles by attending his father's meeting against the party's official candidate, which amounts to gross indiscipline," he said.
Party was expecting a report from the district unit and take decision in respect of Manvendra's alleged activities in the election process soon, the BJP leader added.
