England is part of the "United Kingdom" of Scotland, Wales and Northen Ireland Chief, however it really hasn't been a "United Kingdom" for some years now as Scotland, Wales and Northern Irleand all have their seperate parliaments or asembly's....there's a thought why no seperate English parliament?
The Irish Republic was one part of what was called "Great Britain" but years of brutal misrule by Britain led to the Irish Rebellion and the setting up of the then called Irish Free State, later to become the Irish Republic and a grand a fine nation it has become.
Perhaps England/Britain once the worlds mightiest "superpower" with a huge empire is now paying the price of it's own arrogance for it's past history? I don't know... but I do know there is an unease about this nation amongst her people that I have never witnessed before.
Warmest Regards as always
