Should you find yourself in Casemates Square around midday on the tenth of September, you will be surrounded with a sea of red and white, thousands of Gibraltarians dressed in their national colours, waving the red and white Gibraltar flag with the castle and key motif, and you’ll be in no doubt that Gibraltar has a fierce national identity. For activists and proud Gibraltarians Annette & Paul Tunbridge, Gibraltarian identity is something which shouldn't just be championed every Gibraltar National Day.
