King was convinced to remove bishop no longer showing concern (8)
I believe the answer is:
relieved
'king was convinced to remove bishop no longer' is the definition.
I can't tell whether this definition defines the answer.
'concern' is the wordplay.
I cannot quite understand how this works, but
'concern' could be 'el' (el is a kind of concern) and 'el' is located in the answer.
The remaining letters 'rieved' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'showing' is the link.
Can you help me to learn more?
(Other definitions for relieved that I've seen before include "Alleviated (pain)" , "Replaced on duty" , "Raised the siege of, or generally eased pressure" , "Removed pain or anxiety" , "Grateful" .)
