In a statement issued here on Friday, he said irresponsible, envious and arrogatory attitude of Imran Khan was not bearable.
He added the PTI was targeting the PML-N time and again but the PML-N was trying to save the PTI from complete damage.
The minister hoped Imran's politics of ego, stubbornness and conspiracy would fail, adding positive politics and constructive criticism would be better for the PTI.
He said the PML-N was busy in saving Pakistan from issues and politics of Prime Minister Muhammad Nawaz Sharif had strengthened democratic attitude and system.
