Her claims came in the backdrop of a war of words between Mann and Navjot Sidhu.
In a series of tweets, Kaur said, "CM, Bhagwant Mann; let me today open out a hidden secret from your treasure hunt. You should know that the very honourable chair you are occupying has been gifted to you by your big brother, Mr Navjot Sidhu. Your very own senior most leader had desired Navjot to lead Punjab."
She claimed that AAP national convener and Delhi Chief Minister Kejriwal had approached Sidhu through various channels to lead the state.
