Business leader I'd confused with minister (8)
I believe the answer is:
director
'business leader' is the definition.
'i'd confused with minister' is the wordplay.
'confused' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'minister' becomes 'rector' ('rector' can be a synonym of 'minister').
'id' with letters rearranged gives 'di'.
'di'+'rector'='DIRECTOR'
(Other definitions for director that I've seen before include "Manager, governor" , "He guides and shapes a play or film" , "Boss posing as creditor" , "Business manager or film maker" , "Senior person in a firm, executive or non-executive" .)
