The Supreme Court is likely to take up this week the petition filed by Pakistan Muslim League-Nawaz (PML-N) President Nawaz Sharif seeking a probe into the memo gate issue, as the apex court’s Registrar’s Office numbered the plea after scrutiny on Monday. In his petition, Nawaz has requested the court to summon the respondents, including President Zardari, Husain Haqqani, Mansoor Ijaz, COAS Kayani, ISI chief Pasha and the foreign secretary to explain the memorandum allegedly sent to the US government.
