I would love the Celtic nations of Scotland, Wales, Northern Ireland, the Republic of Ireland, Cornwall, the Isle of Man, and Brittany to form a combined composite international side in some sport.
Even if it is just a one-off or touring side.
It could be a consistent side like the West Indies in cricket.
Or a touring side that combines every four years like the British and Irish Lions.
There are various sports where individual celtic nations could combine to form a strong side in male or female sport.
Be that rugby union, rugby league, cricket, soccer, tennis, gridiron, basketball, baseball, field hockey, ice hockey, golf or other sports.
