As the audios of high-profile personalities continue to get leaked, a sound bite of former prime minister Imran Khan allegedly telling his then-principal secretary Azam Khan to "play" with the US cypher has come to the fore.

In the audio allegedly featuring Khan, a man can be heard talking about the cypher which Khan — time and again — has claimed mentions the "threat" to remove his government. 

Khan allegedly told Azam in the audio — the date of which cannot be ascertained at the moment — that "let's just play" with the cypher and not mention America's name.

In response, Azam tells Khan a scheme of how to use the cypher to forward PTI's political agenda — and in that, he also suggests using Foreign Secretary Sohail Mahmood so the matter can be highlighted at a "bureaucratic level".

The development comes after audio leaks of Prime Minister Shehbaz Sharif, federal ministers, and PML-N Vice President Maryam Nawaz surfaced last week.
