11 August 1964,
Attempted attack on dictator Franco. The 18-year-old Scottish Stuart Christie was arrested in Madrid with explosives attacking Francisco Franco. When this anarchist activist was arrested, dressed in kilt, the traditional Scottish skirt, the press of the time concealed the attempted attack and described it as a "Scottish Transvestite."
