'the data protection commissioner will give you this' is the definition.
The definition suggests a singular noun which matches the answer.

'i agree? with key admission' is the wordplay.
'i agree?' becomes 'righto' (I've seen this before).
'with' says to put letters next to each other.
'key' becomes 'f' (I've seen this in other clues**).
'admission' becomes 'access' (I've seen this before).
'righto'+'f'+'access'='RIGHT OF ACCESS'
