Imprisonment of one contrarian upset about Church of England (13)
I believe the answer is:
incarceration
'imprisonment' is the definition.
('incarceration' can be a synonym of 'imprisonment')
'one contrarian upset about church of england' is the wordplay.
'one' becomes 'i' (Roman numeral).
'upset' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'church of england' becomes 'ce' (abbreviation).
'i'+'contrarian'='icontrarian'
'icontrarian' anagrammed gives 'incarration'.
'incarration' placed around 'ce' is 'INCARCERATION'.
'of' is the link.
(Other definitions for incarceration that I've seen before include "Judicial confinement" , "Imprisonment" , "Jail" , "Captivity" .)
