Here Labour begins true representation in America (6)
I believe the answer is:
uterus
'here labour begins' is the definition.
(as in a mother going into labour)
'true representation in america' is the wordplay.
'representation' is an anagram indicator.
'in' means one lot of letters goes inside another.
'america' becomes 'U.S.' (abbreviation for the United States).
'true' anagrammed gives 'teru'.
'teru' inserted within 'us' is 'UTERUS'.
(Other definitions for uterus that I've seen before include "Here, conceive" , "Organ" , "Producer" , "development centre" , "space for internal development" .)
