Kevin Pietersen statement:
"Contrary to media speculation today, I wish to make it very clear that I did not resign as captain of the England cricket team this morning.
"However, in light of recent communications with the ECB, and the unfortunate media stories and speculation that have subsequently appeared, I now consider that it would be extremely difficult for me to continue in my current position with the England cricket team. Accordingly, I have as of this afternoon decided to stand down as England captain with immediate effect. Notwithstanding my resignation as England captain, I still fully intend to be a part of both England's Test and one-day international squad to tour the West Indies next month and to do all I can to recapture the Ashes during the summer.
"I wish to add that I have principles in my professional and personal life as to how things are done and during my time as England captain I have always been both helpful and direct in my communications with the ECB. At no time, contrary to press speculation, have I released any unauthorised information to the media regarding my relationships with the players, coaches and the ECB itself.
"I am extremely sad and disappointed to have to relinquish the captaincy at such an early stage, especially in a crucial year for English cricket, in such circumstances and particularly when I feel that I have much more to offer the England team as captain. However, this decision will not affect my determination to continue playing international cricket for England, doing all I can to win matches for the team and supporting whoever captains the team in the future."
ECB Managing director Hugh Morris' statement in full:
"The England and Wales Cricket Board have late this afternoon accepted, with regret, the resignation of Kevin Pietersen as England captain.
"Kevin recognised that in the present situation it was impossible to restore the dressing room unity, which is vital if England are to win the forthcoming tour to the Caribbean, the ICC global events or regain the Ashes in the npower Ashes Test series.
"Kevin Pietersen is highly valued as a senior and experienced player and we are delighted that he has indicated he wishes to continue to represent England in all their forthcoming international fixtures, starting in the Caribbean later this month.
"I have an extremely high respect and regard for Kevin Pietersen but this has become an impossible situation given the irretrievable breakdown of the relationship between captain and coach .
"With regard to Peter Moores, the Board determined that he should relinquish his role as England team director.
"I have the greatest respect for the dignity which Peter Moores has shown in recent days when he has found himself under extreme pressure. The ECB wish him well in his future roles.
"I would also like to thank him for his contribution as England Team director and his work as National Academy director.
"Andrew Strauss has agreed to lead the team to the Caribbean. He led the England team with distinction in 2006 when Michael Vaughan was injured.
"The Board will announce the coaching set up for the Caribbean tour as soon as possible and will embark on an immediate search for a coach who can provide England with the best chance of success in the coming years."
