From 1998 to 2002, the competition was contested by 38 teams and included a group stage. The traditional National counties, plus Huntingdonshire and the "cricket boards" of the 18 first-class counties, as well as a Channel Islands team. The 2002 competition, which was won by the Warwickshire Cricket Board, remains the only time a non-National county has won the competition. This format was discontinued after 2002 and the competition is again a purely National Counties affair.
