England doesn't own a single other country. Westminster may be the central government of all four but that's simply a matter of geography, the UK is the body of power rather than England. When you consider it, N. Ireland, Scotland and Wales hold proportional power in Westminster, where they can vote on on all matters concerning England, but they also have their own assemblies which England can not vote on. It can be seen that that Scotland, Wales and N. Ireland actually have a disproportionately more power than England. England is incapable of voting itself free student fees or free prescriptions without the permission of Scotland, Wales and N. Ireland, the latter three can act on this independently.
