Daily describes Romeo Hoskins as sweet talker (7)
I believe the answer is:
charmer
'sweet talker' is the definition.
(synonyms)
'daily describes romeo hoskins' is the wordplay.
'daily' becomes 'char' (both can mean a cleaner).
'describes' indicates putting letters inside (describe can mean to form the outline of).
'romeo' becomes 'R' (phonetic alphabet: alpha, bravo, charlie etc.).
'hoskins' becomes 'me' (where the crossword setter is 'Hoskins').
'r'+'me'='rme'
'char' going around 'rme' is 'CHARMER'.
'as' is the link.
(Other definitions for charmer that I've seen before include "Winsome" , "Highly attractive person" , "relied on for a spell?" , "Lothario?" , "One playing with snake" .)
