LAHORE-Pakistan Tehreek-e-Insaaf central Information Secretary Omar Sarfraz Cheema has vehemently condemned the un-parliamentary language and hurling of personal abusesat each other by PML-N and MQM leaders. In a press statement issued on Thursday, the PTI spokesperson said that PML-N had been a past master at scandal mongering and concocting baseless allegations against political leaders is the cornerstone of their politics. In 1997, he continued, when Imran Khan was talking of principled politics, PML-Nmedia cell was busy concocting personal scandals against him. Though PTI is well aware of the personal exploits, escapades and scandals of the PML-N leadership, but it did not believe in the politics of vicious scandal mongering. Cheema accused PML-N leaders of being devoid of political vision who were trying to shore up their sagging political fortunes through vicious and deplorable slandering. He said that they even went to the extent of labelling Imran Khansformer wife as a Zionist agent and cooked up a groundless, infantile case of smuggling of tiles against her. He further said that Imran Khan earned money abroad for 18 years and brought back his income through legalized channels unlike Nawaz Sharif who laundered illegitimately amassed money and built empire outside Pakistan. He said Mr Khan sold his Flat in London and bought the land for his house in Islamabad. All the funds for this purpose were transferred through legitimate banking channel and its record is available, he said. The PTI leader challenged Nawaz Sharif to apprise the nation through a public debate with him about the actual and real sources of his income through which he has built palatial estate at Raiwind, bought expensive properties at MAYFAIR and other posh areas of UK; and banking on which his sons was investing billions of Pounds abroad. He demanded that the mode of transfer of money for these businesses should also be revealed in front of media.
