ISLAMABAD: Reacting to the remarks of Prime Minister?s Political Secretary Asif Kirmani outside the Federal Judicial Academy on Monday, Pakistan Tehreek-e-Insaf Chairman Imran Khan said the ruling party is attempting to discredit the Panama case Joint Investigation Team (JIT) as it has failed to 'manage' it.

In a message on Twitter, Khan shared a picture of PML-N leaders celebrating the Supreme Court's April 20 judgment and questioned how soon they have forgotten their celebrations over the formation of the JIT.

PTI leader Asad Umar, too, targeted Kirmani in a series of tweets claiming that he should not have questioned the premier?s cousin Tariq Shafi?s summoning by the JIT with regard to the London apartments as the government itself had mentioned Shafi in the Supreme Court when asked where the money for the apartments had come from.

Umar added that the PML-N had no right to complain about how the people whose names were stated in the Panama Papers were walking freely. ?You are the government. Go arrest them,? he said.

In response to the backlash by the PTI leader, Kirmani questioned whether Umar was a member of the JIT which gave him the right to ask so many questions.

?We have answered all the queries posed by the JIT?, he said in a statement in response to Umar's series of tweets.

Pointing fingers at the party, Kirmani stated that Imran Khan and his associates are the ones whose names are in the Panama Papers, not Nawaz Sharif?s.

Meanwhile, commenting on Hasan Nawaz?s media talk following his third appearance before the JIT, Umar said Hasan should read the Supreme Court?s April 20 judgement instead of questioning why summons have been issued to him.

He added that a 2011 letter by the Security and Exchange Commission of Pakistan specifically mentions Hasan Nawaz as a suspect of money laundering. This letter, he stated, was part of the SECP?s case against the Chaudhary Sugar Mills which the JIT claimed has been tampered with by the SECP.
