ISLAMABAD- PTI Chairman Imran Khan today pointed out that no western democratic leader did business while in office as it is a clear conflict of interest. He reminded that Hazrat Abu Bakr (AS) closed down his clothes shop when he became a Khalifa. Khan regretted that the notion of conflict of interest was totally ignored by Pakistani leaders when in power. The Sharifs' entire business has multiplied now and they are one of UK's biggest investors, he added. Khan concluded that going to the steel magnate's house for a cup of tea in New Delhi reflected the priorities of Prime Minister Nawaz Sharif.
