Heartless medical examiner in awkward position (6)
I believe the answer is:
corner
'awkward position' is the definition.
(I've seen this in another clue)
'heartless medical examiner' is the wordplay.
'heartless' says to hollow out the word (remove centre letters).
'medical examiner' becomes 'coroner' (synonyms).
'coroner' with its centre removed is 'CORNER'.
'in' is the link.
(Other definitions for corner that I've seen before include "set-piece" , "pickle" , "Place where two streets meet" , "Angle; nook" , "Monopolise" .)
