British and Irish County Championship - This is the first competition Leinster played. I couldn't find any information either in the form of a forum or who was running it. I did manage to find all the matches that were played and it is from them that I have put together the table you see below. Munster only played 2 matches which they lost and it looks like they were then inactive for a year. For the 4 matches Munster didn't play I have awarded the win to the other team.
