Its clear our current political system is simply unfit for the modern era.
My proposals.
Proportional representation using a system similar to holyrood. this has the advantages of FPTP in that you have each MP representing an area but allows minor parties to get fair representation and regional parties also to get representation. Almost certainly few majority governments and never landslides. Government by consensus.
UK constitutional convention to look at all the issues surrounding devolution and to seek a federal solution. Its the only way I see the UK remaining together in the longer term. also to look at the lords replacement and even is one needed? Many countries are unicameral and also we need a proper written constitution
My preferred outcome is to have 4 (or more) elected proportional parliaments for the UK all with the same powers and a small UK senate to coordinate anything that is not devolved
