Madhya Pradesh Chief Minister Shivraj Singh Chouhan on Wednesday said Congress leader Ajay Singh’s claim that the state government was responsible for his a dispute in his family was the “height of cheapness”, PTI reported.

Singh’s mother, who is the wife of the late Congress leader Arjun Singh, on Tuesday filed a complaint in the magistrate’s court under the Protection of Women From Domestic Violence Act alleging that her sons and daughter-in-law had harassed and forced her out of her home. Ajay Singh is the leader of the Opposition in the state.

In her complaint, 83-year-old Saroj Kumari said that she had no place to live in since her husband died in 2011. She claimed she was not allowed to live in the bungalow that was registered in her name and the names of her husband and son Ajay Singh.

The Congress leader, however, claimed the Bharatiya Janata Party was behind the dispute. “When we brought a no-confidence motion against the Shivraj Singh Chouhan government in July 2013, the BJP made our deputy leader of opposition Choudhary Rakesh Singh Chaturvedi switch sides,” Ajay Singh said, according to The New Indian Express. “A year later when I contested the general elections, one of our MLAs was made to change sides and now it’s happening again.”

Ajay Singh said he would submit the no-confidence motion with the Assembly secretariat, News18 reported. The Monsoon Session of state Assembly starts on June 25.

The chief minister said he wished Ajay Singh would bring his mother back home and give her due respect. “How can Singh blame the government saying it has done something because of which his mother turned against him?” the chief minister said, according to PTI. “This is the height of cheap behaviour...I am pained to see that the wife of a tall leader is facing such problems at the age of 83. Instead of bringing her back and giving her due respect, he is blaming the government.”
