He provides people with the latest information (9)
I believe the answer is:
newsagent
'he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'people with the latest information' is the wordplay.
'people' becomes 'agent' (I am not sure about this - if you are sure you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'the latest information' becomes 'news' (I've seen this before).
'agent' after 'news' is 'NEWSAGENT'.
'provides' is the link.
Can you help me to learn more?
(Other definitions for newsagent that I've seen before include "daily shop" , "shop selling rags?" , "Guardian seller?" , "Seller of papers" , "place selling organs?" .)
