Gibraltar's National Day commemorates the 1967 referendum when the people of Gibraltar voted to reject Spanish annexation by a massive majority. It is celebrated annually on September 10. The day is a public holiday, during which most Gibraltarians dress in the national colours of red and white and among other events, attend a rally. The rally culminates with the release of 30 000 red and white balloons representing the people of Gibraltar. The Conservative MP Andrew Rosindell described the event as "a magnificent celebration of the Gibraltarian people, showing not only their pride in being British, but also their love of their homeland — the rock itself" Gibraltar (IPA: [jÄbrôl'tÉ™r]) is a British overseas territory located near the southernmost tip of the Iberian Peninsula overlooking the Strait of Gibraltar. The territory shares a border with Spain to the north.
