The ICC Executive Board confirmed that the next two World Cups will be 10-team events and also announced that teams will be relegated and promoted on the basis of performance in the ODI league after the 2019 World Cup in England.
The Board had decided in October 2010 to reduce the number of participating teams in the flagship event of the game, which means that small nations, mostly Associate members will not get the chance to play at the big stage. The 2015 tournament will be held in Australia and New Zealand.
"The Board agreed that the 2015 World Cup will comprise the existing 10 Full Members, however, they gave notice to all Full Members that participation in the 2019 ICC Cricket World Cup will be determined on the basis of qualification," an ICC statement said.
