Her Show was on Friday 23 October 2012 but she refused to do that show. Sources in geo news have confirmed that her resignation was because she refused to do the show on asghar khan case because of her favoritism towards PML-N.
When i asked her about this on twitter she said she has resigned long before the asghar khan case.
