Acclaim — Conservative meeting left-winger gets it (6)
I believe the answer is:
credit
'acclaim' is the definition.
(thesaurus)
'conservative meeting left-winger gets it' is the wordplay.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'meeting' is a charade indicator (letters next to each other).
'left-winger' becomes 'red' (red is a kind of left-winger).
'gets' is a charade indicator (letters next to each other).
'c'+'red'+'it'='CREDIT'
(Other definitions for credit that I've seen before include "good character" , "(Account) sum received" , "Believe the time to pay?" , "gives you a good reputation" , "Belief - trust - favourable acknowledgment" .)
