"As Zimbabwe's national cricket captain, I have since May 2004 done my best to lead my team from the front.
"I have given my all under increasingly difficult circumstances, both on and off the field of play.
"My purpose throughout my time as captain has been to guide my team by example and be a professional cricketer committed to the cause of Zimbabwe cricket.
"When I was first blessed with the chance to lead Zimbabwe, I hoped to do so for 20 years. Circumstances have, however, forced me to reconsider.
"Cricket remains my life. God has blessed me with the talent to play cricket and that will remain my purpose as long as I am fit and able to perform to the best of my ability. I still believe I have much to offer cricket, and I will continue to play abroad.
"I know the Zimbabwean public and fans of cricket will want an explanation for my decision to retire. I have already discussed this with my team-mates and friends in cricket.
"It is very difficult for me to go into detail, but I am aware it is my duty to try. I simply want to say that I have not agreed a new contract with Zimbabwe Cricket yet, and the events of recent weeks have sadly persuaded me that it is not in my best interests to do so.
"The personal pressure on me has become unsustainable for me and my family, especially events off the pitch.
"I have recently become a father and this has led me to question what is most important in my life.
"I cannot justify or ignore threats my wife and I have received.
"I no longer believe in the future of cricket in Zimbabwe.
"In the Player Statement we released on November 10, 2005, we were united as professional players in calling for action in Zimbabwe cricket and we made specific mention of our concerns with regard to the incumbent leadership of Zimbabwe Cricket.
"We realised in so doing that we risked consequences. The consequences have come but nothing has happened to address our concerns.
"This is the saddest day of my life, but God has guided me that this is the right decision for me to make in my current position."
