Isnt there loads of division and friction between states in Belgium, Germany, India, and the US?!What about all the other countries in the world that are ‘divided’. Eg Germany or India, the USA or Switzerland, Belgium or Canada, Australia or United Arab Emirates. It doesn’t ‘divide’ them or make them any less a country.
The US written constitution seems to cause more problems than it solves - our way seems much more flexible to move with society’s changes.
Having a constitution that requires more than a 50% majority to change it is surely undemocratic - a tyranny of the old and the minority.
As with many British issues history and tradition is a problem with regional/local government. Really we need a complete remapping, but the loyal cultural attachment (at least by the noisy and influential) to shire borders created by invaders around 1500 years ago frustrates that. That and snobbishness.
For example areas of Surrey inside the M25 that should be part of London Boroughs, and the irrelevance of Surrey as a unit (west and east Surrey have little to do with each other). Or the East Midlands boundaries that bear little relationship to modern life (ie Chesterfield should be in Sheffield-shire)
Also the negotiations and decisions are taken by self interested authority politicians. Things might be different if well informed votes were held and the results considered at ward level.
There should also be more strong-arming - if you don’t want your town to be part of the nearest big town/city ‘shire’ then that shire can start charging you more for using services there.
I’m not a big fan of big unitary authorities - I prefer the Combined Authority model of districts and cities sharing services and larger scale powers (though would prefer a bigger and more representative voting committee than just one leader from each council)
