Sixteen umpires and six match referees have been finalised for the 48-match tournament, the International Cricket Council (ICC) announced. Indian umpire Sundaram Ravi named among the 22 match officials for the league stage of the mega event beginning on May 30 in the United Kingdom. 

With this development, Ravi once again will be the only Indian officiating in the tournament. He had recently received a barrage of criticism, including from India captain Virat Kohli, for failing to spot a no-ball from Sri Lanka pacer Lasith Malinga in an IPL game last month.
