Union Jack Union Jack The Union Jack, or Union Flag, is the national flag of the United Kingdom. The flag also has an official or semi-official status in some other Commonwealth realms: for example, it is a ceremonial flag in Canada by parliamentary resolution, and known there as the Royal Union Flag. Further, it is used as an official flag in some of the smaller British overseas territories. The Union Flag also appears in the canton (upper left-hand quarter) of the flags of several nations and territories that are former British possessions or dominions, as well as the state flag of Hawaii.
Union Jack is in progress, though these are now normally held at shore establishments. No law has been passed making the Union Jack the national flag of the United Kingdom: it has become one through precedent. Its first recorded recognition as a national flag came in 1908, when it was stated in Parliament that "the Union Jack should be regarded as the National flag". A more categorical statement was made by Home Secretary Sir John Gilmour, in 1933 when he stated that "the Union Flag is the national flag and may properly be flown by any British subject on land."
