No idea Kev, but the point I'm making is that the league structure has lost 2 clubs - Bury and FC Oswestry Town, so technically speaking they can admit 2 clubs without displacing anyone.
Whether the Isle of Man or FC Bury are the right choices I don't know, but have they been admitted on the basis of their size and fan base? It would certainly have been difficult to deny FC Bury a place?
