In 2015, a major chunk of Khan's income comprised the gain of a little over Rs 0.2 crore from the sale of an apartment in Islamabad, followed by Rs .98 crore of foreign remittances, the report said. The documents also show Rs .34 crore as his agricultural income, it added.
In 2016, his total income dropped to Rs 1.29 crore of which he earned Rs 0.74 crore from "foreign services" alone.
In contrast, the income of the Leader Opposition of the National Assembly Shahbaz Sharif continued to see an upward trend as his net income rose from Rs 0.76 crore in 2015 and crossed Rs1 crore in 2017.
Former president Asif Ali Zardari's agricultural income that comprises most part of his net income stood at Rs 10.5 crore in 2015. It rose to Rs 11.4 crore in 2016 and surged to Rs 13.4 crore in 2017. He holds 7,748 acres of land.
While Zardari's son Bilawal Bhutto-Zardari appears richer than him in terms of assets he holds in Pakistan and elsewhere, he lags behind the father in terms of income, according to the documents. Bilawal's total income registered over 100 per cent rise in a year, as it surged from over Rs .23 crore to Rs .47 crore in 2016.
