Allocated party went ahead (5)
'allocated' is the definition.
Both the answer and definition are past participle verbs.
Maybe there's a link between them I don't understand?
'party went ahead' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'went ahead' becomes 'led' (I've seen this before).
Can you help me to learn more?
(Another definition for doled that I've seen is "Given modest share".)
