Crime of minister wanting leader removed (5)
I believe the answer is:
arson
'crime' is the definition.
(I've seen this before)
'minister wanting leader removed' is the wordplay.
'minister' becomes 'parson' ('parson' can be a synonym of 'minister').
'wanting leader removed' means to remove the first letter.
'parson' with its initial letter taken off is 'ARSON'.
'of' acts as a link.
(Other definitions for arson that I've seen before include "Criminal burning of property" , "Roans (anag)" , "burning problem" , "Sonar (anag.)" , "It may get you in court" .)
