Why is Imran Khan against the new army chief Asim Munir?

Islam Abad (94 news) Senior journalist Shahzeb Khanzada, while presenting an analysis, has said that the former Prime Minister Imran Khan did not want Asim Munir to become the new army chief. 2 Seniors were made Army Chief and Chairman Joint Chiefs of Staff.
He further said that PTI made this whole issue controversial because of Asim Munir. Imran Khan has said that his problem is not who should become army chief, the problem is that Asim Munir should not become. Imran Khan liked Asim Munir very much, made him DGISI, he 6 Mah remained in this position for months, then news came that Asim Munir had presented evidence to Imran Khan, which was related to Bani Gala and his family, in which corruption was mentioned.

General Asim was expecting Imran Khan to take action but Imran Khan took action against General Asim and removed him from the post. That is why Imran Khan did not want Asim Munir to become the Army Chief because it was not a matter of principle but his personal matter that the then DGISI kept evidence which the then Prime Minister did not like.
