Upon NCP's recommendation, Gavit was sacked from the ministry two days ago.
State NCP president Bhaskar Jadhav told reporters here that Gavit had been asked to stop his daughter from joining BJP and contesting from Nandurbar against Congress veteran Manikrao Gavit.
"However, he did not do so, which proves that the move was deliberate. He has been given a show-cause notice and the decision to expel him from the party will be taken after we get his reply," Jadhav said.
"Gavit's daughter, Hina, is unmarried, and stays with the father. She could not have taken the decision without the father's approval," Jadhav said.
When asked whether in NCP's view unmarried women cannot take decisions on their own, Jadhav said, "I did not mean to say that."
He also lashed out at the BJP leader Gopinath Munde for creating a divide between the Gavit father-daughter duo. "Because of Munde, Gavit's political career is in peril," he said.
