He was an important member of the PML-N and our close associate, he remarked.

“He was counted among the loyal companions of Mian Nawaz Sharif and the party,” he said, adding, “Irfan Siddiqui’s services to the party will always be remembered.”

His academic services and national insight will remain a beacon of light for future generations. He was a kind, gentle and extremely refined person,” he noted.
