The party said that Purohit's action "breached" organisational discipline, and asked him to reply to its state president Raosaheb Danve within three days, failing to which action would be taken against him.
"Purohit, a former minister and MLA from Colaba in Mumbai, has been asked to explain his position and give a written explanation within three days," a BJP spokesperson told PTI.
In the video, Purohit is shown to agree with the interviewer, whose identity is unknown, that Modi and Shah are the only ones wielding power in the party and there is no internal democracy in the BJP.
On the Centre's policies, he was shown saying that "Narendra-bhai is doing good work, but he should avoid the mistakes he is making. Some of his decisions are alienating certain groups likes traders, who are the BJP's hardcore supporters.

He is also heard describing Chief Minister Devendra Fadnavis as "helpless" in the face of "pressure from above" and from influential individuals like builder and Malabar Hill MLA Mangal Prabhat Lodha and ridiculing Raj Thackeray as a "bogus" leader.
The sting also shows Purohit claiming that he is the senior most BJP leader after Eknath Khadse (Excise Minister) in the state and "should have been made a minister".
Purohit has claimed that the voice in the video was not his. He has demanded that the video be sent for forensic testing.
"The sentiments which a senior BJP legislator like Raj Purohit has expressed, is shared by many in that party," Pawar said.
