Ashley Giles has left his position as the managing director of England men's cricket following a shambolic Ashes showing from the Test team.
England's Ashes campaign was effectively over after just 12 days of cricket in Australia, with some woeful batting and questionable selections coming amid a 4-0 loss.
The England and Wales Cricket Board (ECB) met this week to review England's performances and Giles, who spent three years in his position, has been dispensed with.
Head coach Chris Silverwood and batting coach Graeme Thorpe are also under pressure, with ECB chief executive Tom Harrison suggesting that large scale change is needed.
"I'm extremely grateful to Ashley for his commitment and contribution to England men's cricket over the last three years," Harrison said in a statement.
"Under his leadership the teams have scored some notable results, most memorably the dramatic victory in the 2019 ICC Men's Cricket World Cup, while dealing with some of the most challenging times English cricket has ever been through.
"He's highly respected throughout the game and has made a huge contribution to the ECB and England men's cricket.
"Off the back of a disappointing men's Ashes this winter we must ensure we put in place the conditions across our game to enable our Test team to succeed."
Giles said: "I'd like to thank everyone for the support they've given me, particularly all the staff and the players, as well as the board for giving me this opportunity.
"The past couple of years have been incredibly challenging and I'm proud of what we've been able to deliver in the toughest of circumstances. This has undoubtedly protected the future of the game in England and Wales.
"Despite these challenges, over the past three years, we have become 50-over world champions, the top ranked T20I side in the world, we remain the fourth-ranked Test team and our Under-19s have just reached the World Cup final for the first time in 24 years. I wish all our players and staff great success for the future.
"I'm now looking forward to spending some time with my family before looking at the next challenge."
