hmmm, this as a whole is very bad. Amarinder is from Congress and him not coming means even congress wants to follow the footsteps of BJP, there is Sidhu but he is termed more as friend of Imran than someone from Congress. But I don't think it's that bad for them, Sushma not coming already cleared the BJP stance. Now, I don't exactly know the internal strength of Khalistan movement, but inviting some leader who is mildly proponent of Khalistani movement would have been a smart choice. My recommendation would been inviting some Sikh from AAP, since both PTI and AAP have same moto, to help the poor, at-least this way it would have shaken Indian politics a little bit and forced other to make a more positive response.
