England batsman Jonathan Trott is returning home from the Ashes tour due to a stress-related illness and is to take a break from the game.
He will miss the remainder of the tour and his return to cricket will be determined in due course.
In a statement, he said, "I don’t feel it is right that I’m playing knowing that I’m not 100% and I cannot currently operate at the level I have done in the past.
"My priority now is to take a break from cricket so that I can focus on my recovery. I want to wish my team mates all the very best for the remainder of the tour.”
Hugh Morris, Managing Director England Cricket, added: "Jonathan Trott is an incredibly talented cricketer who has proven himself time and again for England.
"The cricket side of things is unimportant now, all that matters is that Jonathan is given the time, support and space he needs to recover. We fully support his decision to leave the tour and the ECB will provide all the assistance we can to help Jonathan and his family through this period.
"Jonathan has asked for privacy while he recovers and I would urge everyone to respect that."
Trott's departure with stress-related illness comes seven years after Marcus Trescothick left an Ashes tour in similar circumstances and although he was able to play cricket again, he has been unable to travel abroad, which effectively ended his international career.
He now captains Somerset and has already expressed his sympathy for Trott, and called for everybody to give him time to get well again.
"Your health is far more important than any game of cricket you play," he told Sky Sports.
Four years after Trescothick's departure from Australia, Michael Yardy left England's World Cup squad in 2011 and has subsequently made a successful return to playing with Sussex.
England lost the opening Test in Brisbane by 381 runs.
