The current Union Flag dates from 1 January 1801 with the Act of Union 1800, which merged the Kingdom of Ireland and the Kingdom of Great Britain to form the United Kingdom of Great Britain and Ireland. The new design added the red saltire cross of St Patrick's Flag for Ireland. This saltire is overlaid on the saltire of St Andrew, but still beneath the cross of St George. The Irish saltire is arranged countercharged with the saltire of St Andrew, so the white is always on the clockwise side of the red. The arrangement has introduced a requirement to display the flag "the right way up"; see specifications for flag use, below. The additional white stripe is added (as with the St George's cross) to prevent "colour next to colour", a heraldic imperative.^[5]

This Saint Patrick's cross is problematic in several ways. Firstly, the symbol does not have much emotional resonance since its history is so thin and hard to find; some believe that it was essentially 'invented' for the purposes of inclusion in the Union Flag. One possible origin is from the arms of the Fitzgerald family (Dukes of Leinster) who were sent by Henry II of England to aid Anglo-Norman rule in Ireland and has rarely been used as an emblem of Ireland by the Irish; a harp, a Celtic cross, a shamrock, or latterly an Irish tricolour have been more common. However, the exact origin of the flag is unknown, with evidence of saltires being present on ancient Irish coins and maps. The St Patrick's saltire flag has been used in more recent times for St Patrick's Day in Northern Ireland and by both state and civil organisations wishing to avoid the sectarianism that may be implied by the use of either the tricolour or symbols of Unionism, including the recently formed Police Service of Northern Ireland.

The current flag is blazoned Azure, the Crosses Saltire of St Andrew and St Patrick, quarterly per saltire, countercharged Argent and Gules, the latter fimbriated of the second, surmounted by the Cross of St George of the third, fimbriated as the saltire.
