Roughly ignore old punter (9)
I believe the answer is:
gondolier
'punter' is the definition.
(I've seen this before)
'roughly ignore old' is the wordplay.
'roughly' indicates an anagram.
'ignore'+'old'='ignoreold'
'ignoreold' with letters rearranged gives 'GONDOLIER'.
(Other definitions for gondolier that I've seen before include "Venetian boatman" , "to leave Red Lion disorientated" , "Singular SO" , "Craftsman" , "Venetian boater" .)
