Due to leave centre, release planned (10)
I believe the answer is:
deliberate
'planned' is the definition.
(I've seen this before)
'due to leave centre release' is the wordplay.
I cannot quite understand how this works, but
'release' could be 'liberate' (synonyms) and 'liberate' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for deliberate that I've seen before include "debate" , "Done intentionally" , "Planned" , "Consider carefully" , "Well considered" .)
