N didn't stop supply, but KPK after getting more then it's share still had shortages because of smuggling which had nothing to do with N league. If corrupt officials in KPK are smuggling your share of wheat then why blame N? Do you think there is unlimited supply of wheat in punjab? On top of that it was subsided wheat by punjab government, meaning punjab government was paying more to farmers but selling for less in market. This is why this so called cry of ban by PTI didn't go anywhere once facts and figures were presented. Now I most say in last couple of years smuggling has been taken care of somewhat and that problem no longer exist. It was likely rampant in ANP era who are known for corruption.
