Union Jack

The Union Jack is the national flag of the United Kingdom, combining elements from the flags of England, Scotland, and Northern Ireland. It features a red cross (St. George's Cross for England), a white saltire (St. Andrew's Cross for Scotland), and a red saltire (St. Patrick's Cross for Northern Ireland) on a blue background. The design symbolizes the political union of these nations. Although it is commonly referred to as the flag of the UK, it is officially called the Union Flag, and the term "Union Jack" is technically correct only when the flag is used at sea.
