Sir: Serious note has to be taken of the foul language used by Imran Khan. His indiscriminate adherence to profanity despite the presence of national television cameras and his audience, including men, women and children of all ages, is becoming atrociously unpalatable. Mr Khan is a party leader carrying the responsibility of acting in a dignified and exemplary manner. It is no wonder that his followers have strewn extremely vile and abusive comments against anyone who so much as breathes a word against their cherished leader.MOBEEN SHAHVia Email
