Force displaying which female MP has issues (8)
I believe the answer is:
emphasis
'force' is the definition.
(I've seen this before)
'displaying which female mp has issues' is the wordplay.
'displaying' says the answer is hidden in the clue.
'EMPHASIS' can be found hidden inside 'which female mp has issues'.
(Other definitions for emphasis that I've seen before include "Special importance or prominence given to something" , "Stress laid on, eg, words" , "Importance; priority" , "Stress, accent" , "Stress given to a word" .)
