ISLAMABAD: Pakistan Tehreek-e-Insaf (PTI) Chairman Imran Khan on Saturday scoffed at Prime Minister Nawaz Sharif over his participation in the World Economic Forum (WEF). In a message on Twitter, Kaptaan called the prime minister’s decision to join the forum as a supreme irony. “Nawaz is off to Davos, at taxpayer expense again, where the theme is anti-corruption,” he said. “Nawaz Sharif’s vast experience in white collar crime probably qualifies him to address the gathering on money laundering and tax evasion etc,” he added. The visit also coincides with the Panama leaks case being heard by the Supreme Court. Besides Nawaz, former army chief Raheel Sharif is also attending the forum. Separately, PTI Secretary General Jahangir Khan Tareen said Nawaz has no moral justification to stay in his office following the BBC report. Tareen underlined that everything has become clear after the BBC report and Nawaz has no justification to stick to his office. He went on to say that the PTI is fighting a war to steer the country out of quagmire of corruption and to give new generation a corruption-free Pakistan. “New generation stands with us in this war,” he added. According to a recent BBC report London flats are owned by the Sharifs since 1990s.
