This is with reference to the most embarrassing news discussed on a TV channel in its program called Kal Tak telecast on April 30. It has been disclosed that in the Higher Secondary School Examination, someone impersonated on behalf of a sitting MNA Haji Pervaiz. This incident has disgraced PML-N, the party to whom he belonged, a lot. I think Haji Pervaiz must be punished. -ENGR MUNAWAR HUSSAIN, via e-mail, May 1.
