This is the most important moment in the bullfighting calendar - when reputations are made, or broken, in an afternoon. This year will see one great change. The abbatoir at the back of the bullring will stay locked. Rather than risk disease, they have decided to burn all the carcasses. Even the bull's ears and tails, the gory trophies handed to the matador at the end of the fight, have been banned.
Bullfighters now get fake ones instead.
