Hmmm.
The son of a Cypriot waiter, whose mother deserted the family when he was three, resulting in him being taken into care and placed in a council-run children's home, who still managed to get a place at Oxford (where he acieved a First Class Honours BA degree before going on to achieve both a Doctorate and a Fellowship). That reads like the start of a true 'rags to riches' story to me, which would seem to exemplify Labour's aspirations to create social mobility, rather than typifying an 'ermine clad parasite'.
Oh, BTW, he entered party politics when he was elected to Oxford City Council.
