Andrew Strauss is stepping down from his role as England's director of cricket with Andy Flower replacing him on an interim basis.
The former England skipper took time off during the summer due to family illness and now leaves permanently though he is to take up a more flexible role with the ECB.

In his place Andy Flower will take up the role as director of cricket until a permanent successor is found.
Strauss said in a statement that, with 2019 being such a vital year ahead, the England team needs someone who can devote the necessary time to the role.
He said next year is "potentially the most important the game has had in this country" with the World Cup being held in England and Wales closely followed by a home Ashes series.
"We have an incredible opportunity to do something special," he added.
"It is vital that the director of cricket can give consistent guidance and support to England Cricket through this period.
“The role in cricket requires total focus and commitment to deliver the best results, yet right now I need far more flexibility than could ever be possible in my position in order to support my family."
Flower, former England coach, who led the team to Ashes victory in 2013, will continue in the job until December and is then expected to join the England Lions on their tour of India in January.
It is anticipated that a new full-time director of cricket will be in place for England's tour of the West Indies early in the New Year.
The England ODI squad are currently in Sri Lanka on tour and play two warm-up games on Friday and Saturday before the first international at Dambulla on Wednesday.
That is the first of the five-match series. The teams then meet in a T20 international and then three Test matches in November.
England are 2/5 to win the ODI series with Sri Lanka 2/1. England are 11/2 to win the series 5-0.
