The International Cricket Council (ICC) said in a statement its executive board had approved a 14-team contest in Australia and New Zealand in 2015, with 10 places going to the Test-playing nations. The second-tier teams will have to pre-qualify for the remaining four places.
The ICC also announced the 2019 World Cup would be a scaled-down 10-team event, with the top eight places going to the top-ranked teams and two berths being awarded in a pre-qualifying tournament.
The about-face on the 2015 World Cup reverses the ICC's decision to limit the tournament to the sport's 10 full-member teams - which left countries such as Ireland, the Netherlands, Canada and Kenya on the sidelines.
