One stunner captivating male in charge (7)
I believe the answer is:
impeach
'charge' is the definition.
(I've seen this before)
'one stunner captivating male' is the wordplay.
'one' becomes 'i' (Roman numeral).
'stunner' becomes 'peach' ('peach' can be a synonym of 'stunner').
'captivating' means one lot of letters goes inside another (I've seen this in other clues).
'male' becomes 'm' (common abbreviation).
'i'+'peach'='ipeach'
'ipeach' enclosing 'm' is 'IMPEACH'.
'in' is the link.
(Other definitions for impeach that I've seen before include "Charge with a crime (against the state)" , "Arraign, charge" , "Charge with major crime" , "Charge with treason, etc" , "Arraign - revile" .)
