The Professional Cricketers' Association (PCA) is seeking a new chief executive after Angus Porter confirmed his plans to leave.

Porter joined the players' union in March 2010 having previously worked at BT, Abbey National and Thomas Cook. With the organisation facing several challenges, he presided over a much-improved relationship with the ECB and a more settled method of agreeing central contract payments.

He also stabilised the organisation's commercial operations and improved the education programmes provided to players to warn them of the dangers of match-fixing, gambling and drugs.

"We are very sad to see him leave," Glamorgan's Mark Wallace, the PCA chairman, said. "But we are very grateful for the exceptional management, guidance and commitment he has given.

"Angus joined us at a challenging time for the organisation and under his direction the PCA has steadied, developed and thrived. He is held in the highest regard not only at the PCA, but throughout the cricketing world."

Porter's departure is not unexpected. He is understood to have notified the organisation around a year ago of his desire to move on and a recruitment firm, Odgers Berndston, has been appointed to find his successor.

They may not have to look far. The PCA's current assistance chief executive, Jason Ratcliffe, is a strong contender for the role. Porter is expected to remain in place until a successor is appointed.
