It will be structured as a round robin league with home and away fixtures alternating between tournaments. The Cup was initially due to be a revival of the British Home Championship, which was cancelled in 1984 because of increasing fixture congestion, but due to the lack of interest from the Football Association, the Football Association of Ireland was invited to take England's place. The Welsh FA hold out the possibility of the English joining at a later date.
In April 2008, it was announced the tournament had been delayed until 2011 at the earliest due to fixture congestion. Under the proposed format, matches would be played in February and May, with the location rotating on a "tournament-by-tournament basis".
