Sir: The Punjab chief minister has learnt his lesson. He made a promise to sacrifice anything to reach the truth about the Model Town affair. And as a first instalment he has sacrificed his law minister and principal secretary. Whether they are guilty or not is not his concern. He has a dozen more to save his skin. But the Pakistan Tehreek-e-Insaaf chief does not appear to be satisfied with this ‘sacrifice’; he wants the removal of the chief minister along with his elder brother. Whether this demand is justified or not is not the PAT chief’s concern.Mir Tabassum MairajIslamabad
