What a hollow statement, really. An opportunist statement on the back of the Guardian Cameron debacle, maybe? 
How does he intend to measure 'privilege' anyway? I am a person, more privileged than some, less privileged than many. Does he intend to work only for the under-privileged then? Who qualifies? That doesn't work either.
He ought to have followed in Mother Theresa's footsteps in that case as he is sounding like a phoney saint. Is he likely to give up his MP perks? Nope.
