Hisham al-Kabbani, the khalifah of the late Nazim al-Haqqani, of Cyprus. I believe he is based in the USA somehwere, though I can't recall where.
You have tahirs fanboys attending this anyway. Kazim pasha is a big fan and his son is part of MUQ. Plus you have folk from Jamia nizamia attending who are also responsible for supporting and spreading fitna e padri.
Hafiz Ehsan has declined attendance. His email is attached. Update* Sorry I deleted the image as his phone number was included in the email. I will ask him for permission before uploading the image. He basically declines acceptance on the grounds that an invitation was extended to padri sahib.
I think its a made-up rumour. I've heard this going around a little but it would have been massive news if he was attending.
Sufi conferences should have staunch sunni ulama attending. Otherwise, awaam will think these are sufis whereas hisham allows women kissing his hands and mixed gatherings. Khushtar noorani should take note.
Some say he is nothing to confirm thou Hmm. I wonder if the ulema of India such as Shaykh ul Islam Sayyid Madani Miyah or Huzur Taajush Shaariah Mufti Akhtar Rida Khan will get invites
