Facebook page, before launching an attack on Chief Minister
Parkash Singh Badal in another post. Navjot Kaur, who along with her husband,
Navjot Singh Sidhu, had not been enjoying the best of relations with her party's Punjab unit as well as the
SAD leadership, posted a message on 1 April 2016. It said, "Finally I have resigned from the BJP. The burden is over." Navjot Kaur exposed a senior state government medical officer running a private hospital in
