It may not be around much longer. If our Scottish cousins decide to go it alone in 2014, the Union Jack will lose one of its core constituent parts, the St Andrew's Cross.
So all the more reason to celebrate the British flag this weekend — if you're not a republican that is. Our strange, asymmetrical, oddly striking national colours will no doubt feature heavily in bunting- and dressing up-related celebration.
And as this selection demonstrates, the red, white and blue concoction photographs rather well. From eggs and walls to fluttering bunting, the Union Jack can look grand — beautiful even — as well as kitsch.
