Fool, maybe, in party doing a pirouette (3)
I believe the answer is:
pud
'fool maybe' is the definition.
(I know that fool is a type of pud)
'party doing a pirouette' is the wordplay.
'party' becomes 'dup' (Democratic Unionist Party).
'doing a pirouette' says the letters should be written in reverse (a pirouette is a spinning dance move).
'dup' in reverse letter order is 'PUD'.
'in' is the link.
(Other definitions for pud that I've seen before include "duff?" , "hand" , "Cooked sweet dish" .)
