Last night almost all TV channels were showing interviews of prominent leaders of PML-N and MQM. I was stunned and astonished to hear the language used by Mustafa Kamal from MQM, and also Zaeem Qadri from PML-N. There are a lot of issues, where political parties do not agree with each other. But they ought to express their views politely. Mostly the people who viewed the show and the manner in which they were having conversation were not happy. I request all political parties and their leaders to exercise caution and restraint. SH ZAMEER UD DIN SHAKEEL
