Have confidence in removing leader in charge of the country (6)
I believe the answer is:
rustic
'of the country' is the definition.
(I've seen this before)
'have confidence in removing leader in charge' is the wordplay.
'have confidence in' becomes 'trust' (synonyms).
'removing leader' means to remove the first letter.
'in charge' becomes 'ic' (abbreviation for 'in charge').
'trust' with its initial letter taken off is 'rust'.
'rust'+'ic'='RUSTIC'
(Other definitions for rustic that I've seen before include "clodhopper" , "Peasant; roughly made" , "Of the country, bucolic" , "To do with the countryside, or made of rough timber" , "Rural - simple" .)
