BBC Sport - 2015 Cricket World Cup is reduced to 10 teams
The International Cricket Council has confirmed its decision to cut team numbers for the World Cup from 14 to 10 starting with the 2015 tournament.
It means there is no place for Ireland, who beat England in the 2011 World Cup.
Only full ICC members - India, Pakistan, Sri Lanka, England, South Africa, New Zealand, Australia, West Indies, Bangladesh and Zimbabwe - will compete in four years time.
For the 2019 event, the 10 teams will be decided by qualification.
The possibility of a 12-team tournament was also discussed by the ICC's executive board at a meeting in Mumbai, but it opted to approve its previous decision to exclude all associate and affiliate member nations from the next edition of the competition.
Apart from Ireland, who also beat Pakistan at the 2007 World Cup, the other nations outside the ICC's full members to take part in the 2011 event were Kenya, Canada and the Netherlands.
Associate members had opposed the change and Ireland bowler Boyd Rankin apparently described Ireland's exclusion as a "shambles" on Twitter.
"Thanks ICC!! What does Irish cricket got to do?," appeared on an account purportedly belonging to the 26-year-old.
However, Ireland captain William Porterfield has spoken optimistically of his team's chances of proving themselves as one of the top-10 teams in world cricket.
The ICC also announced that the new one-day international league due to run between April 2011 and April 2014 will incorporate relegation and promotion from 2019.
The event is to run separately to the Cricket World Cup to add more meaning to 50-over matches outside the tournament.
