Right, McPero has already said Ireland/Northern Ireland can be formed. Other than that it is UK and it will not be split down into Counties or Regions of UK.
Like the rules say
9. On permission of the event organiser, nations can team up in certain circumstances (eg. The Balklands, Scandinavia) This is on the basis that no nations in that area have entered a team.
LameHorse has been given permission to form the UK team (Scotland, Wales, England)
Just like Ledge has been given permission to make the Balkans team.
Simple now, if you don't like the way the tournament is being run, then don't come or try to come.
