While watching the rugby tonight in the pub we engaged in some constitutional debate. I was told that Wales is not, in fact, a country but a dominion of England. Apparently Wales was conquered by England in the 14th or 15th Century (the exact date didn't come up in the pub discussion), whereas Scotland and Ireland (subsequently NI) were countries that England entered into union with. I was told that this is the reason that, while Scotland and NI can have a parliament, Wales only gets an assembly. Also that this is why there is no Welsh in the Union Flag.
Anyone know the actual constitutional position?
