Grand National Festival horse Giovinco dies after falling mid-race, enraging animal rights activists 24 hours before Aintree’s big race, where a ring of steel has been built to stop protest invasion

Giovinco, aged seven, fell during the Mildmay Novices' Chase, the first race of Ladies' Day. His death comes just a day before the showpiece event, for which a 'ring of steel' has been prepared.
