Chaudhary Sher Ali, father of State Minister Abid Sher Ali, took exception to Sanaullah and other PML-N leaders at a press conference here.
He went on to say that Prime Minister and Chief Minister Punjab Shahbaz Sharif must learn lessons from by-elections in Lahore.
PML-N will be doomed if immediate steps are not taken to save the party, he added.
He termed Punjab Law Minister Rana Sanaullah as the ‘top most law violator of the province’.
He said he would announce his next line of action in couple of days.
