Party brought about noise next to golf course (7)
I believe the answer is:
pudding
'course' is the definition.
(course of a meal)
'party brought about noise next to golf' is the wordplay.
'party' becomes 'dup' (Democratic Unionist Party).
'brought about' says the letters should be written in reverse.
'noise' becomes 'din' (din can mean a loud noise or disturbance).
'next to' is a charade indicator (letters next to each other).
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'dup' reversed gives 'pud'.
'pud'+'din'+'g'='PUDDING'
(Other definitions for pudding that I've seen before include "Pease - -" , "Sweet course" , "Chubby person" , "Dessert course" , "Fool, perhaps" .)
