Suspect Ethel is surrounded by babies of political writers (12)
I believe the answer is:
pamphleteers
'political writers' is the definition.
'pamphleteers' can be an answer for 'writers' (pamphleteer is a kind of writer). I'm not certain of the 'political' bit.
'suspect ethel is surrounded by babies' is the wordplay.
'suspect' indicates anagramming the letters.
'is surrounded by' is an insertion indicator.
'babies' becomes 'pampers' ('pamper' can be a synonym of 'baby').
'ethel' with letters rearranged gives 'hlete'.
'hlete' put inside 'pampers' is 'PAMPHLETEERS'.
'of' is the link.
Can you help me to learn more?
(Another definition for pamphleteers that I've seen is " writers of tracts".)
