I really admire the naivety of your answer. The ECP has still not been disclosed the sources of PTIs massive fundings for more than five years now. The matter is still pending on a friendly courts STAY order.The list of funders includes many non Pakistanis of Indian and other origins whos sources are of dubious nature.
I am sure you dont think that the bulk fundings are only provided by Aleem Khan,Jahangir Tareen,Kareem Daddy or Arif Naqvi (abraaj gp). It should be noted that all four of them are local/international convicts with the later just got released on a 20 Million pound bail in UK for massive FRAUD.
