Duty of the superior toff, being above inferior English press (8,6)

'duty' is the definition.
(noblesse oblige is a kind of duty)

'of the superior toff being above inferior english press' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is present in the answer.
'being' could be 'b' (B is an example) and 'b' is found in the answer.
'inferior' could be 'less' ('less' can be similar in meaning to 'inferior') and 'less' is found within the answer.
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
'toff' could be 'nob' (UK slang for a wealthy or upper-class person) and 'nob' is present in the answer.
This explanation may well be incorrect...
