Minister concealed by Uncle Richard (6)
I believe the answer is:
cleric
'minister' is the definition.
(I've seen this before)
'concealed by uncle richard' is the wordplay.
'concealed by' indicates a hidden word.
'CLERIC' can be found hidden inside 'uncle richard'.
(Other definitions for cleric that I've seen before include "Type of cloth, perhaps" , "Priest caught in circle" , "Eg, priest" , "One in holy orders" , "One ordained" .)
