Claim to have put in the cupboard of (7)
I believe the answer is:
profess
'claim' is the definition.
(I know that profess is a more specific form of the action claim)
'put in the cupboard of' is the wordplay.
'put in' is an insertion indicator.
'the cupboard' becomes 'press' (term for a large cupboard).
'press' going around 'of' is 'PROFESS'.
'to have' acts as a link.
(Other definitions for profess that I've seen before include "Make open declaration of" , "State insincerely" , "Affirm faith in (religion)" , "State openly" , "Affirm, acknowledge" .)
