I do apologise if my previous posts were seen as glib or even offensive to our northern members.
However we all have an opinion and I will stick by mine. However possibly i explain mine a little better.
For a hundred years the 4 nations of the United Kingdom have developed, utilised and exploited national industries - rail, oil, gas, air travel / freight, postal service, NHS, defence the list goes on.
If one member was to split, it's unfair to cherry pick which parts of those industries you want to 'claim as rightfully yours' and reap those rewards as yours and charge the others to have.
So if Scotland was to steal oil, does the remaining 3 nations steal back all the subs and naval assets and open up bases in Wales and decimate billions in yearly defence income for Scotland? Same for the Northern raf bases. Or do we threaten to charge you for overflying UK airspace from your airports via the Air corridors and make you fly out to Norwegian airspace and then South just to get to europe? Maybe shut down your entire postal service? Remove you from NICE or other drugs and science services?
All of these (and many many more) are important national services that contribute, cost, enhance or degrade the 4 nations collectively. Hence my comment of you can't have your cake and eat it.
We either stay together or share it proportionally for the good or worse as separate nations. Maybe if you squint a bit then that does indeed sound a bit 'federal'... If so then I would support a federal United Kingdom.
