Imaan Mazari is only known to PTI supporters because of his mother, Shireen Mazari (of Naya Pakistan fame). She is also known for her ultra-liberal views (you could call her a liberal extremist). She had a squabble with Hamza Ali Abbasi in the past over LGBT rights and other issues.
So you should have a clear picture of her in your head by now, but the most interesting thing is that her mother, who is always outspoken about everything, has never expressed any concern about her daughter’s lifestyle. Though Imaan has complete freedom to live her life as she wishes, as the daughter of a well-known political party, she undoubtedly has an impact on the minds of the younger generation.
