Cry out for new creches (7)
I believe the answer is:
screech
'cry out' is the definition.
'new creches' is the wordplay.
'new' is an anagram indicator.
'creches' anagrammed gives 'SCREECH'.
'for' is the link.
(Other definitions for screech that I've seen before include "Loud harsh cry" , "Loud shrill cry" , "Terrifying sound" , "High pitched shout" , "cry of horror" .)
