Work hard for Starmer's team (6)
I believe the answer is:
labour
'work hard' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for labour that I've seen before include "hands?" , "Workers" , "Donkey-work" , "opposition" , "Hard work, party" .)
