Equality is difficult in a country where 50m of its 60m people are English. And, Goatfell, the reason that the Scots, Welsh and Northern Irish won't take part is because they've said they won't take part. This is in case it jeopardises their unique status (if three teams can be unique!) as 'national' teams from countries that aren't nation states (yet.....)There are no other examples of 'regions' (which includes England)playing international football.
