Influence from others to leak reports initially to the media — not quite certain (4,8)
I believe the answer is:
peer pressure
But I can't explain it at all! Could you help me understand?
(Other definitions for peer pressure that I've seen before include "Influence from others in one's group" , "The influence of the Lords" , "that whips people into line?" , "Influence of one's contemporaries" , "Compulsion to conform to one's contemporaries" .)
