The current and second Union Jack dates from 1 January 1801 with the Act of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. The new design added a red saltire, the cross of Saint Patrick, for Ireland. This is counterchanged with the saltire of St Andrew, such that the white always follows the red clockwise. The arrangement has introduced a requirement to display the flag "the right way up" (see specifications for flag use above). As with the red cross, so too the red saltire is separated by a white fimbriation from the blue field. This fimbriation is repeated for symmetry on the white portion of the saltire, which thereby appears wider than the red portion. The fimbriation of the cross of St George separates its red from the red of the saltire.
