England selector James Whitaker is to leave his post as part of a major overhaul within the England and Wales Cricket Board.
Whitaker, an England selector for a decade, will step down at the end of the month as the ECB plans a new approach to picking players for all forms of international cricket.
Fellow England selectors Angus Fraser and Mick Newell will retain their positions for now and can apply for new roles, the ECB has confirmed.
"The England and Wales Cricket Board is to introduce a new approach to scouting, assessing and selecting players for the senior Test, T20 and One-Day sides, ensuring greater connection right through the international pathway," the ECB said in a statement.
"In line with this new integrated approach, England national selector James Whitaker will step down from his role at the end of March.
"This season will see the introduction of a scouting system with designated discipline-specific scouts, including the current ECB national lead coaches, providing information to a three-strong selection panel, made up of a new national selector, a full-time independent England selector and the England head coach."
The new national selector's role will be advertised this week, with the ECB looking to have a new man in place in time for the next selections in mid-May before the Test series against Pakistan.
"Current England selectors Angus Fraser and Mick Newell will remain in place until new positions have been filled and are free to apply for the new roles," the ECB added.
Director of England Cricket Andrew Strauss said the overhaul was not related to recent results, but a formalised scouting network would help the ECB gather more knowledge about a particular player's strengths.
