ISLAMABAD: Pakistan Tehreek-e-Insaf (PTI) leader Usman Dar on Thursday said Defence Minister Khawaja Asif lied regarding his Iqama [contract].

Addressing the media in the federal capital, the PTI leader termed Asif as part of the 'mafia' in Sialkot. 

He also questioned how the defence minister's wife is able to invest millions in a housing scheme. 

Dar further said that if Asif's money trail is questioned, he will also present a letter from an Arab country. 

PTI Spokesperson Fawad Chaudhry, also in attendance, said the PTI will submit references against federal ministers in the Election Commission of Pakistan (ECP). 

Chaudhry also alleged that Prime Minister Nawaz Sharif is the chairman of a company in Dubai. 

Asif is a senior PML-N leader who is also reportedly tipped to be the interim premier in case Prime Minister Nawaz Sharif is sent packing by the Supreme Court in the Panama Papers case.

Responding to the allegations, Asif had earlier said the salary he received through the Iqama has been declared with the ECP and Federal Bureau of Revenue for the last 27 years.

Dar, who lost the 2013 General Elections to Asif in the NA-110 constituency, said Asif did not declare his Iqama [contract] and employment with the company in the nomination papers he filed with the Election Commission of Pakistan (ECP).
