Pakistan Tehreek-e-Insaaf (PTI) leader Jahangir Tareen on Saturday said his party would approach the Lahore High Court (LHC) to seek disqualification of Punjab Chief Minister Shehbaz Sharif on corruption charges. Speaking to media here, , Tareen said that the PTI and PML-N will be major parties competing in next elections in Punjab. To a question regarding Panama Papers case, he said: "It seems difficult that Prime Minister will get clean chit in Panama leaks case".
