A local TV channel recently aired a programme on the issue of removal of billboards in Lahore. The fact that DG PHA did not want to discuss this issue with the Billboard Advertising Association's representative on air should tell you something about transparency in his department. Rather than meeting behind closed doors, the PHA high officials should let the Lahorites know that they are not making any underhand deals with any mafia as was done in the past. -BABAR NIZAMI, Lahore, via e-mail, September 17.
