Social centre in Anglesea to distribute… (4)
I believe the answer is:
dole
'to distribute' is the definition.
(I've seen this in another clue)
'social centre in anglesea' is the wordplay.
'social' becomes 'do' (both can mean a party).
'centre in' indicates the central letters.
The middle of 'anglesea' is 'le'.
'do'+'le'='DOLE'
(Other definitions for dole that I've seen before include "Dish (out sparingly)" , "State assistance" , "State benefit (colloq.)" , "Money received from the state while unemployed" , "Unemployment benefit (sl.)" .)
