Politics: UK: Why, how the semantic gap between Britain, UK, and England?

OpenDemocracy, a website far to my left, but always enjoyed, has recently started publishing a satellite blog OurKingdom, recently outputting an onputting thawt piece entitled "Britain and England: A Case Of Split Identity" (Sep29,2k9) by David Rickerd.

OurKingdom is a part of openDemocracy’s new site. Our special focus is on the destiny of Britain. We will discuss Britain’s nations, institutions, constitution, administration, liberties, justice, peoples and media and their principles, beliefs, identity, destinations and character. In a word our democracy in its broadest meaning, its history and future, from cultures and religions, participation and issues of centralisation and authority to equality, rights, responsibilities and who rules.

I'm trying to intice comment by reformationalsUK as to the grand geopolitical ideas rather skillfully but provocatively navigated by Rickerd.
