I don’t agree with this-the UK either with devolved parliaments or as a federal country is simply too complex. A second upper chamber is necessary as it is in most other countries of a similar nature.
Maybe one concept worth pursuing would be regional assemblies, but with an all-England upper house? The idea could be that the regional assemblies would be responsible for public services (police, fire, schools, etc) while the all-England upper house could take responsibility for the laws that govern those public services. The new English Senate could be indirectly elected in the same way that the Bundesrat is, that is, the members would be appointed by the governments of the regional assemblies.
Above that, you'd just need a UK House of Commons which would have roughly 317 members (150 from England, 50 from Scotland/Wales/NI, 14 Overseas Territories, 3 Crown Dependencies). The UK House of Lords would then be also elected, with perhaps 51 Lords from England, 17 from each of Scotland/Wales NI and a Senator representing the Overseas Territories and Crown Dependencies. I'd make all elections on a 4 year cycle, with the devolved parliaments being elected halfway through the 4 year parliamentary cycle.
I think the biggest issue in England is the strange system of governance that isn't unified. I can barely make sense of all the different layers of administration there, whereas the other countries have a straightforward system of local councils and national parliament.
So that 83% of the population have 50% of the representatives, and a Welshmans vote counts 6 times as much as someone in England? I think I'll pass on that particular deal.
I think the idea is that the UK Federal Parliament would only deal with matters of UK-wide importance, with everything else being devolved. This way, you'd avoid things like the example above with the SNP voting against extended opening hours on a Sunday, because they simply wouldn't have the competence to do so. England would be conceding the right to rule over the rest of the UK, but having nearly 50% of the representatives would still be a very powerful voting bloc.
I think before we start thinking about regional assemblies (or even an English Parliament) we need to figure out what responsibilities are best handled at what level.
Yes, absolutely. There is a mess right now with responsibilities differing between devolved administrations, and I would argue strongly that each devolved administration should have the same powers. Spain has the same problem with their asymmetric devolution and differing Statutes of Autonomy.
To be honest, I think a big part of the issue with England is that it's not really viable to have a two tier system of government (local council and national parliament), but that introducing regional as well as national parliaments would mean a lot of parliamentarians. There was a model proposed for Cyprus that the state-level MPs would also serve as federal MPs, which might be a viable solution. You'd elect representatives to the regional assembly, and then the English Parliament would be comprised of all the regional assembly members. If the English Parliament made laws and then the regional assemblies implemented them, you'd retain the regional differences while only requiring a single vote every 4 years.
Perhaps the solution would be regional assemblies but with only part time parliamentarians?
