Material available publicly about tour with corrupt clinician. (2,11)
I believe the answer is:
in circulation
'tour with corrupt clinician' is the definition.
The definition suggests a singular noun which matches the answer.
'material available publicly about' is the wordplay.
I cannot quite see how this works, but
'material' could be 'cu' (Cu is an example) and 'cu' is located in the answer.
'available' could be 'on' (I've seen this in other clues) and 'on' is located in the answer.
'about' could be 'c' (abbreviation for circa) and 'c' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for in circulation that I've seen before include "Being generally used" , "Being used by the public" .)
