Fifty to one a top man has taste! (6)
I believe the answer is:
Here is my best explanation:
'taste' is the definition.
'fifty to one a top man' is the wordplay.
'fifty' becomes 'l' (roman numeral).
'to one' becomes 'li' (I've seen this in other clues).
'a top' means to remove the first letter.
'man' becomes 'king' (king is a kind of man**).
'li' with its initial letter taken off is 'i'.
'has' is the link.
