One from past who could make corps see red (11)
I believe the answer is:
predecessor
'one from past' is the definition.
(someone who preceded others)
'make corps see red' is the wordplay.
'make' indicates anagramming the letters.
'corps'+'see'+'red'='corpsseered'
'corpsseered' anagrammed gives 'PREDECESSOR'.
'who could' acts as a link.
(Other definitions for predecessor that I've seen before include "One who went" , "Earlier job holder" , "One previously in job" , "Previous occupant of a post" , "Something now replaced by another" .)
