Say Labour do? (5)

I believe the answer is:

party

I believe this clue is a double definition.

'say labour' is the first definition.
(I know that Labour is a type of labor party)

'do?' is the second definition.
(do is a kind of party)

(Other definitions for party that I've seen before include "Celebratory social gathering" , "Political group; function" , "Social occasion - political group" , "Crew" , "festive" .)

I've seen this clue in The Sun.
