Lewis Hamilton has hit back at suggestions by F1 supremo Bernie Ecclestone that the abuse directed at the newly crowned champion was just 'a joke'.

I believe that SOME of it was just a joke. The guys with the blacked-up faces were certainly a joke, as one of the "perpetrators" admits, and was not racist. Hamilton has, however, also suffered a great deal of REAL racist abuse. That is not a joke, and should be condemned by Ecclestone.
