1D Former Culture Minister I remember finally (5)
I believe the answer is:
nadir
'1d former' is the definition.
I can't tell whether this definition defines the answer.
'culture minister i remember finally' is the wordplay.
'culture minister' becomes 'nad' (I can't explain this - if you can you should believe this answer much more).
'finally' indicates one should take the final letters.
The last letter of 'remember' is 'r'.
'nad'+'i'+'r'='NADIR'
Can you help me to learn more?
(Other definitions for nadir that I've seen before include "Point of greatest despair" , "The lowest point of anything" , "Low-water mark" , "most unsuccessful point" , "Lower one cannot get!" .)
