Flag of Scotland
From Tardis Wiki, the free Doctor Who reference
The flag of Scotland was a diagonal white cross on a blue background. When King James VI of Scotland became James I of England as well, he proposed a merging of the Scottish flag with the English flag, which was a red cross on a white background. This merged design would eventually be known as the Union Flag. (TV: The Gunpowder Plot [+]Loading...["The Gunpowder Plot (video game)"])
