Labour's successful outcome in the 1950s? (4,6)
I believe the answer is:
baby boomer
'labour's' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for baby boomer that I've seen before include "One of many born after WW2" , "Person born shortly after WWII" , "born just after the war?" , "Someone born in the decade after WWII" , "Joey" .)
