Heads of Daily Telegraph maintaining weird stain's removed (7)
I believe the answer is:
distant
'removed' is the definition.
('distant' can be similar in meaning to 'removed')
'heads of daily telegraph maintaining weird stain's' is the wordplay.
'heads of' suggests taking the first letters.
'maintaining' is an insertion indicator.
'weird' indicates anagramming the letters.
The initial letters of 'daily telegraph' is 'dt'.
'stain' anagrammed gives 'istan'.
'dt' going around 'istan' is 'DISTANT'.
(Other definitions for distant that I've seen before include "Remote in time or place" , "Aloof" , "Far away" , "overseas?" , "Unfriendly; far off" .)
