A day after Pakistan Tehreek-e-Insaf leaders attended the all-party meeting against the ongoing Indian "aggression" in Jammu and Kashmir, its chief Imran Khan has announced that his party would boycott the joint session of parliament, terming "it would be like endorsing Sharif as premier which the party would not do so"."We have debated about the matter in our party and decided to boycott the session tomorrow because we think Nawaz Sharif has lost legitimacy to remain a Prime Minister," Imran Khan told the media on Tuesday.The cricketer-turned-politician went on to say that since the Prime Minister has "evaded" giving answers on Panamagate controversy for six months now, there was no point attending the joint session.The PTI chief also offered two options to Sharif to resolve the stand-off between the opposition and government. "The first option for Nawaz (Sharif) is that he should resign as a Prime Minister and any other leader of his party can replace him. The second option for him is that he should present himself for the accountability."Imran insisted that the purpose of the joint session was to express solidarity with Kashmiris which the PTI has already done in its all-parties meeting and Raiwind March.According to him, the PTI strongly supported the cause of Kashmiris, saying that his two senior leaders Shah Mahmood Qureshi and Shireen Mazari gave their great stance in the meeting.
