The award ceremony at Crufts was overshadowed by a protester who ran onto the stage as the winner of Best in Show was presented with the trophy after a competition of seemingly never-ending drama. As Rebecca Cross and her Scottish terrier Knopa were handed the trophy at the prestigious dog show, the suited man charged in front of the winning pair, holding aloft a sign which read 'Mutts Against Crufts'. The demonstrator was quickly hauled off stage by four members of security as the shocked crowd watched in astonishment, eventually leaving owner Ms Cross and Knopa to enjoy their victory.
