Flag of the United Kingdom

"The United Kingdom of Great Britain and Northern Ireland uses as its national flag the royal banner known as the Union Jack or Union Flag (despite popular belief, both terms are technically correct). ... The current design of the flag dates from the union of Ireland and Great Britain in 1801. It consists of the red cross of Saint George (patron saint of England), edged in white, superimposed on the Cross of St Patrick (patron saint of Ireland), which are superimposed on the Saltire of Saint Andrew (patron saint of Scotland). Wales, however, is not represented in the Union Flag by Wales's patron saint, Saint David, as at the time the flag was designed Wales was part of the Kingdom of England. ... Name: Union Jack or Union Flag. Use: National flag. Proportion 1:2. Adopted: 1 January 1801. Design: A white-fimbriated symmetric red cross on a blue field with a white-fimbriated counterchanged saltire of red and white." [Flag of the United Kingdom. Wikipedia]
