Ministers resist scheme to follow parliamentary leadership (7)
I believe the answer is:
priests
'ministers' is the definition.
(church ministers)
'resist scheme to follow parliamentary leadership' is the wordplay.
'scheme' indicates anagramming the letters.
'to follow' is a charade indicator (letters next to each other) (some letters go after or follow others).
'leadership' says to take the initial letters.
The initial letter of 'parliamentary' is 'p'.
'resist' anagrammed gives 'riests'.
'riests' put after 'p' is 'PRIESTS'.
(Other definitions for priests that I've seen before include "Religious leaders" , "Church leaders" , "Spiritual leaders" , "Ordained ministers" , "Clergymen" .)
