Dictatorial nurses see proof (10)

Ross

I believe the answer is:

impervious

'proof' is the definition.
('impervious' can be similar in meaning to 'proof')

'dictatorial nurses see' is the wordplay.
'dictatorial' becomes 'imperious'.
'nurses' is an insertion indicator.
'see' becomes 'v' (Latin 'vide', used to direct a reader to a source).
'imperious' going around 'v' is 'IMPERVIOUS'.

(Another definition for impervious that I've seen is " impossible to pass".)

I've seen this clue in The Times.
