Tim Lamb is to step down as chief executive of the England and Wales Cricket Board at the end of September, the ECB said.

Lamb, 51, has held the post since 1997.

"I feel that after nearly eight years in the role I have probably taken the ECB as far as I can," Lamb said in a statement on the ECB web site on Thursday.

"As the organisation moves into the next phase of its development with a revised strategic plan and new challenges to face, it's time to move on and hand over the reins to someone else."
