ISLAMABAD - Pakistan Tehreek-e-Insaf (PTI) on Friday claimed that it would submit more proofs in the Supreme Court that Maryam Nawaz, daughter of Prime Minister Nawaz Sharif, was still dependent on his father.

The party also said that it would also proof the timeframe during which Sharif family purchased London properties.

Vice-President PTI Shah Mehmood Qureshi along with senior party leaders including Jehangir Khan Tareen and Asad Umar, while addressing a press conference at Bani Gala said that wrong impression was being given by the ruling PML-N that perhaps the PTI had no proofs against the Sharif family in connection with Panama leaks.

He said proofs gathered by PTI negate the PM’s claims that in 2005, he shore up revenue for his children to start business after selling a steel mill in a Gulf country.

"We have proofs that Sharif family got the offshore companies registered and made millions of rupees in investments [from] these firms before 2005," Secretary General PTI leader Jehangir Khan Tareen said.

In 1993, 1995, 1996 and 2004 five flats were purchased in Mayfair through three offshore firms, he said adding the properties were than pledged to obtain loan.

"It can be verified through detailed judgment of Al-Toufeeq case in London High Court," he said.

Tareen said the companies owned by the family during the period 2001-2005 had a clear mention of one of the Mayfair's flats as residential address of Hasan Nawaz.

According to statements submitted by the PM's children before the SC, Maryam Nawaz had been receiving money as gift from his father and his father in receiving gift money from his son, he said.

The income in returns shown by Maryam does not match her expenses, Tareen said.

Qureshi said that Sharif family claimed Maryam's name in 2011 was mentioned in a column of dependent, as there was no separate column for independent children.

But Maryam in 2011, while talking to a TV has said that she and her brothers did not own property in London and that even she lived in her father's house.

Replying a question, Shah Mehmood Qureshi said the PML-Q, the PTI and the JI would jointly move a joint resolution in the Senate over the issue of formation of a “controversial” seven-member committee to probe who leaked “wrong” news about a high-level national security meeting.

A retired judge who had been made head of the committee had connections with the Sharif family, he claimed.
