The ICC said their elite panel of eight umpires and five referees would be on duty throughout the tournament and would be supported by 11 members of the ICC's international panel of umpires plus referee Denis Lindsay.

The ICC said each umpire had international one-day and, in some cases, Test-match experience and had undergone performance assessment.

"With more than 50 games to be played during the World Cup there will be a heavy workload for all match officials," ICC general manager David Richardson said in a statement.

"The International Panel was created for occasions such as this, to supplement and support the eight full-time members of the Elite Panel.

The ICC has also appointed two umpires from the United Cricket Board of South Africa first class list, Ian Howell and Shahid Wadvalla as well as officials from participating Associate Member nations: Michael Henry (Canada), Chris Pickett, (Netherlands), Rockie D'Mello (Kenya) and Jeff Luck (Namibia).

International Panel umpires will be appointed to on-field and third official duties, while the UCBSA and Associate umpires will act as fourth officials for the group stage of the cup.
