Party after party in place of hard work (6,4)
I believe the answer is:
labour camp
'place of hard work' is the definition.
The definition suggests a singular noun which matches the answer.
'party after party' is the wordplay.
'party' becomes 'labour' (Labour Party is an example).
'after' says to put letters next to each other.
'party' becomes 'camp' (both can mean a group of people).
'labour'+'camp'='LABOUR CAMP'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for labour camp that I've seen before include "Penal institution where inmates are forced to work" , "Place giving convicts hard physical work" , "Left followers" , "here doing punishing work" , "prison" .)
