Brussels first acquires information identifying someone espousing discredited science (8)
I believe the answer is:
eugenist
'someone espousing discredited science' is the definition.
I can't judge whether this definition defines the answer.
'brussels first acquires information' is the wordplay.
'brussels' becomes 'EU' (European Parliament is based in Brussels).
'first' becomes 'ist' (ist resembles 1st).
'acquires' indicates putting letters inside.
'information' becomes 'gen' (gen can informally mean information).
'eu'+'ist'='euist'
'euist' enclosing 'gen' is 'EUGENIST'.
'identifying' acts as a link.
Can you help me to learn more?
(Other definitions for eugenist that I've seen before include "Discredited scientist" , "Breeder" .)
