As Bob Dylan once said, the times are a-changing, and so we might have to consider some unusual possibilities. For one, Scotland seceding from the UK is definitely on the cards - it might not happen, yes, but what if it did? Would the Union Jack have to be edited to accurately represent the new sum of its parts?
I certainly think it would, although previous attempts to edit the flag to include Wales has never been very successful. In theory the dragon on the Union Jack would be quite inspirational, but it just doesn't look right in my opinion. It's even worse if you try cramming some yellow and black in there too, representing the flag of St. David.
I've come to the conclusion that the most logical form for the flag would be to simply colour the blue on the flag in black, as in this image:
I don't think that looks too shabby, does it?
To put it simply - the black would represent the Welsh, the red saltire is of course representative of the Northern Irish (that may be up for debate) and the St. George's cross would represent England. I think it'd be the most practical way of doing things - it means that all of the Union Jack merchandise only needs 1 quick colour change, after all.
I'm genuinely interested to see if anyone can come up with something interesting to represent a new Union Jack without Scotland. I invite you to share them with us in this thread.
