Up until recently one of the greatest strengths of the United Kingdom has been it’s unwritten constitution, which is underwritten by lots of unwritten constitutional conventions and precedents. But underneath these lies an unspoken truth which makes the UK work, or has done. England dominates the UK.  From a point of view of population,, some 65 millions wealth and GDP – England dominates the UK and therefore the existence of the UK and it’s governance depends upon power sharing between England and other equal regions in Britain – Scotland, Northern Ireland and Wales.  Of Course within England, the unspoken truth is that London dominates in exactly the same way.  The act of Union in 1707 saw Scotland united with England and Wales, building on a shared monarch from 1603. This started to unravel politically in 1979 with the Devolution debate and the Conservative Party no longer enjoying support in Scotland, yet governing from power in England. The Devolution in Scotland and Wales has led to rival parliaments in Edinburgh and Cardiff and the Scottish Referendum debate led to a vow of greater devolution for Scotland and the idea of English Votes for English Laws in Westminster.  The latter opens up the real danger of Westminster being turned into a Conservative dominated English parliament where it would be impossible for a Scot or Welsh MP becoming a Prime Minister or holding cabinet role outside of Scottish or Welsh secretary.  The power and wealth of an English parliament in Westminster would dwarf Cardiff or Edinburgh. Political questions such as Brexit from the EU would see England threaten to drag other nations into historic alignments against their will and interest. This would trigger both Scottish Independence and a Welsh Devo Max.  A Federal Britain, with regional devolution for English regions such as Cornwall, London and Yorkshire would see  a balancing  and sharing of power along traditional lines which might offer a better hope of a continuing union to the advantage of all the regions and nations of Britain.  There are those however who would seize at English Nationalism as a vehicle to 
pursue xenophobic right wing politics and English Devolution might well cause political realignment towards the right at the expense of British democratic values. Liberal Democrats should oppose EVEL and English Nationalism as undemocratic, toxic to the British United Kingdom in favour of a Federal arrangement built upon shared power, values and interests
