Where MP has issues displaying use of force (8)
I believe the answer is:
emphasis
'force' is the definition.
(I've seen this before)
'where mp has issues displaying use' is the wordplay.
'use' indicates a hidden word (I've seen 'using' mean this (the answer is used in part of the clue)).
'EMPHASIS' is hidden within 'where mp has issues displaying'.
'of' is the link.
(Other definitions for emphasis that I've seen before include "Special importance or significance" , "Stress, accentuation" , "Force" , "Importance; priority" , "Weight" .)
