On further questions, he said he did not want to comment on the issue.
He also addressed a function of the Bharatiya Janata Yuva Morcha (BJYM), the party's youth wing, at the state BJP headquarters where a portrait of Sardar Patel was installed on the dias for the first time at a party function.
Speaking there, he insisted that he had the highest respect for Sardar Patel.
Before commencement of the function, party workers paid tributes to Patel. Chouhan said: 'I do not want to go into the contents of senior party leader Jaswant Singh's book. I also feel sad about his expulsion from the party, but whatever comments he made in his book regarding Patel were wrong.'
Back from Shimla where he attended the BJP's introspection meeting (chintan baithak), Chouhan has also warned party workers and leaders that he doesn't want a Jaswant Singh like episode in Madhya Pradesh.
'Indiscipline will not be tolerated in the organisation in the name of freedom of expression. The party's thought would be the worker's thought. Deviation from it cannot be allowed'.
