Consensus about endlessly diverse supplier of education (10)
I believe the answer is:
university
'supplier of education' is the definition.
'consensus about endlessly diverse' is the wordplay.
'consensus' becomes 'unity'.
'about' is an insertion indicator.
'endlessly' says to take the centre (the ends of the words are removed).
The middle letters of 'diverse' are 'ivers'.
'unity' going around 'ivers' is 'UNIVERSITY'.
(Other definitions for university that I've seen before include "1's scene" , "Academic establishment" , "Cambridge?" , "Place of higher learning" , "Seat of learning developing" .)
