By ‘other minor countries in the UK’, I assume you mean, 3 of the 4 countries in the UK.
Whether we like it or not, the UK is heading towards becoming a federalised union of four nations. In particular many feel the UK government has had an ‘England first’ stance for too long, which has pushed us in the direction of ever-greater devolution. The position of UK prime minister, and the UK government, doesn’t have the clout it once did.
