The basic problem is the lack of an English parliament without which they keep trying to lay claim to the British parliament at Westminster.
Without addressing this issue there will be no settlement within the UK, whether the Scots choose independence or not.
Once the English, who unwittingly lost their independence on 1707 at the same time the Scots knowingly have it up, have an assembly or parliament like the Scots, Welsh and Northern Irish, the he West Lothian question and 90% of the other frictional issues would melt away.
An English assembly might be based somewhere in the centre of England,say Manchester or York, and would help move political and economic power away from the south coast – highly desirable in this day and age.
We could also cement what has been a mutually beneficial union (in economic terms at least) for over 300 years, by building HS2 in the right place, linking Manchester, Leeds, York, Newcastle, Edinburgh and Glasgow in a big circle, complementing the existing express lines into London on the west and east coasts.
Anything else I need to cover?
Oh yes, 29ers and 26ers are both good but I just don’t get 650b.
