Morgan for one redesigned spire (5)
I believe the answer is:
piers
'morgan' is the definition.
(Piers Morgan)
'one redesigned spire' is the wordplay.
'one redesigned' is an anagram indicator.
'spire' with letters rearranged gives 'PIERS'.
'for' is the link.
(Other definitions for piers that I've seen before include "Landing stages" , "Supports for bridge spans" , "Jetties" , "Old ploughman" .)
