Newly banned writer has no time to be a wage slave (11)
I believe the answer is:
breadwinner
'a wage slave' is the definition.
(thesaurus)
'newly banned writer has no time' is the wordplay.
'newly' is an anagram indicator.
'has no' is a deletion indicator.
'time' becomes 't'.
'banned'+'writer'='bannedwriter'
'bannedwriter' with 't' taken out is 'bannedwrier'.
'bannedwrier' is an anagram of 'BREADWINNER'.
'to be' is the link.
(Other definitions for breadwinner that I've seen before include "worker" , "Family's main earner" , "Main earner of the family" , "Person bringing home the bacon" , "Family's financial supporter" .)
