ISLAMABAD: Pakistan's opposition parties have labelled Prime Minister Imran Khan a "security threat" to the country, a report said. Shehbaz Sharif, the president of the Pakistan Muslim League-Nawaz (PML-N), said in a statement that Khan had put Pakistan in the crosshairs in a desperate attempt to keep power. He emphasised that, in his desperation and frustration, Khan was endangering Pakistan's diplomatic relations, and that it was critical that he be barred from making these disastrous comments. "If the letter isn't visible, that signifies there isn't one. Imran Niazi, as he normally does, is telling a new lie "Sharif said. "This conspiracy letter was the latest fake story to save Imran's sinking ship, following his false narrative of corruption and lies about establishing a mirror image of Riyasat-i-Madina." At a press conference, PML-N leader Khawaja Asif criticized Khan for claiming the United States as the source of the "threat letter." "There is no doubt that the United States may cause us problems," he said, adding that the country might throw Pakistan into a financial crisis and make it difficult for it to acquire oil. PPP Chairman Bilawal Bhutto-Zardari informed a television station that he had not seen "the previous Prime Minister's speech." He claimed Khan had enslaved Pakistan to the International Monetary Fund, undermined Kashmir policy, and sabotaged the China-Pakistan Economic Corridor.
