Was there really a foreign funded threat against prime minister Imran Khan?

What happened:   It is pertinent to mention that Imran Khan, in his Sunday speech at the Parade Ground in Islamabad, said that he had evidence of the written threat posed against his government. However, on March 29, Express Tribune reported,  “Pakistan’s relevant authorities have seen no evidence yet that there is an international conspiracy to topple PM Imran Khan through the vote of no-confidence motion moved by the opposition parties.”  Details:   Subsequently, since the claims made by the premier, many eyebrows have been raised, and questions have been asked about the legitimacy of the letter. Later, the relevant authorities answered the questionnaire regarding the foreign threats; according to Express Tribune, as they wrote,  “Relevant quarters revealed that they had no knowledge of any such plot and neither did they see any evidence.”  More: Furthermore, Express Tribune quoting sources wrote,  “If the threat was so serious, why was the meeting of the National Security Committee was not called immediately. It is believed that concerning quartes and officials in the FO were upset even if there was a certain plot… the premier should have taken up the issue at the relevant forums instead of raising the subject in public.”
