Aristocrat with millions invested in Lebanon unfortunately (8)
I believe the answer is:
nobleman
'aristocrat' is the definition.
(I know that nobleman is a type of male aristocrat)
'millions invested in lebanon unfortunately' is the wordplay.
'millions' becomes 'm' (abbreviation).
'invested in' means one lot of letters goes inside another.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'lebanon' with letters rearranged gives 'noblean'.
'm' going inside 'noblean' is 'NOBLEMAN'.
'with' is the link.
(Other definitions for nobleman that I've seen before include "Male aristocrat" , "Member of the aristocracy" , "High-ranking male" , "Earl, say" , "I have a title" .)
