Agreed, and suggested company should replace leader (8)
I believe the answer is:
complied
'agreed' is the definition.
(complying is a kind of agreeing)
'suggested company should replace leader' is the wordplay.
I cannot really understand how this works, but
'company' could be 'co' (abbreviation) and 'co' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for complied that I've seen before include "Met standards" , "Acted in accordance with the law" , "Abided, by rules say" .)
