England have appointed former international and Warwickshire director Ashley Giles as head coach of their limited overs sides.
Andy Flower will remain as England's Team Director and will continue to be responsible for the preparation and playing strategies, but not the day-to-day leadership of the limited over sides.
Both Flower and Giles will remain as England selectors, with the latter to take charge of the side for the first time against India in January and February before turning his focus to the ICC Champions Trophy next summer.
"I am delighted to have been appointed England ODI and T20 Head Coach and to be given an opportunity to coach at international level," said Giles.
"I have worked closely with Andy in recent years as a selector and am looking forward to continuing to work together and to build on the progress that has been made with the ODI and T20 sides in recent years."
Hugh Morris, Managing Director of England Cricket, said: "England cricket has enjoyed considerable success over the past five years.
"In order to build on that success we know that we need to look for ways to evolve and it has become clear that the Team Director role needs to change if we are to ensure we are utilising the role as effectively as possible.
"Bringing in a Head Coach for the ODI and T20 formats allows the Team Director more time to plan for forthcoming series and tournaments and also have a more realistic and sustainable work life balance."
The 39-year-old Giles, who led Warwickshire to the County Championship in September, is also an England selector. He took 143 wickets in 54 Test matches for his country between 1998 and 2006.
An ECB statement added: "The change in structure will provide a more efficient and sustainable use of coaching resources, ensuring that both coaches have an opportunity to prepare thoroughly for each series as well as interacting more regularly with other important areas of England cricket.
"Andy Flower will have accountability for the results of England cricket and will continue to tour with the England Test side during both home and away series."
Will Ashley Giles be a success in his new role?
