Louise I've applied the same principle for the senate as in the USA, where each state receives 2 senators, despite the huge variation in population.
Unlike the US, this would only be for defence, foreign affairs, international treaties etc
the HoC would have its seats for these issues with PR
England could choose whether it wants its national parliament to be 100 seats, or 500 which iirc is roughly the number of English seats in the HoC now,
or maybe even say 5 separate 100 seat parliaments for the main English regions.
I consider it essential if a federal system is to function, that each part of it can vote against starting / joining a war.
Otherwise, as now, England outvotes everyone
That's not the same thing at all about agreeing on steps during the war - politicians shouldn't micromnage that, anyway.
However, the decision to actually go to war, or for that matter join / leave an organisation like the eu, NAFTA, NATO needs to be unanimous among the nations, not just steamrollered through by England, as now.
The UK is one of the most centrally run countries in the developed world and the whole country suffers from inappropriate decisions made centrally at Westminster.
Maybe with these different levels of government, each with a lot of respon sibility, to make it worthwhile,
we could actually attract more competent, dedicated politicians,
instead of the current pathetic specimens
