I should just point out that there is nothing federal about the United Kingdom. In actual fact, ever since it was first instituted in 1707, its tendency has been to centralise power in London.
In the beginning, most day to day issues relating to governance which affected people’s lives were decided at the parish level. Gradually, power started to move towards London and away from local areas, and all sovereignty rests in London. This centralising tendency is one of the reasons btw, that the American colonists rebelled against their London masters and set up their own country, and made sure that the individual states retained sovereignty on certain issues which the federal government was defined to have no competence over (well, until the US Civil War and after, but thats another story)....
No doubt a good, stiff bout of Maoism would help clear the cobwebs out and remind people there of why they really don't need cradle-to-earlygrave socialism.
They're well into that now aren't they.
