The Pakistan Tehreek-e-Insaf (PTI) said on Tuesday that the documents proving Prime Minister Nawaz Sharif as Maryam Safdar’s custodian have been submitted in the Supreme Court (SC). PTI Spokespersons Fawad Chaudhry and NaeemulHaq – while talking to media persons outside the SC – revealed that the prime minister’s children had expenditures more than their incomes but on the other hand, Maryam’s income tax, utility bills and other expenses were zero.“The behaviour and trends of the prime minister’s family has given enough information to the court regarding the matter,” PTI’s spokespersons claimed.They said that Maryam imported a used BMW in 2006 but paid no tax and her tax returns revealed that she had no income. However, her travelling expenditures were over Rs 3.6 million during the last two years, the PTI officials added.“So, where did her travelling funds came from?” the spokespersons questioned.They said that during 1999, Hussain Nawaz was living in a flat with student status but during his interview, he revealed that the flat’s rent came from Pakistan.They hammered on the point that Hussain had no income till 1999, ‘so from where did the amount to purchase the flat come from?’Naeem stated that the documents submitting in the SC proved that Prime Minister Nawaz is guilty in the Panama case and Maryam has been living in the Prime Minister House – under Nawaz’s guardianship – contradicting her claim of being independent.
