Phil Simmons is to become the new coach of his native West Indies as soon as the World Cup is over.
Former Test batsman Simmons, 51, is to leave the same post with Ireland and will be in charge of the Windies when England arrive for their tour of the Caribbean next month.
Cricket Ireland confirmed Simmons’ departure on Friday.
Trinidadian Simmons has been Ireland coach for eight years, during which they have been the pre-eminent force among the associate nations and have qualified for every International Cricket Council global tournament.
Under Simmons, Ireland have pulled off World Cup victories over England in 2011 and West Indies themselves just last month.
They will face England again in a one-off one-day international in May, at the conclusion of their opponents’ Test tour of the Windies.
Simmons said: “I’ve had eight wonderful years as Ireland’s head coach, and will always cherish the memories of those great days we’ve shared.
“The players and staff at Cricket Ireland have been simply magnificent. The wins in the World Cups over full members were all special, as we showed the world just what Irish cricket is capable of.
“The Irish and West Indians are very similar in their nature and outlook on life and sport.
“They welcomed me into their country, and I engaged with their sporting heritage and culture - and I’m a richer, better person for it.”
