Northamptonshire have appointed Ray Payne as acting chief executive.
A local resident, Payne has been a member of the board since the start of 2014 and temporarily takes over the post vacated by David Smith last week.
Payne, whose business background is in the leisure and hospitality industry, said: “I am delighted to be given this opportunity by the board during this transitional time.
“I look forward to further developing the recent progress made with the club’s facilities and the many opportunities that exist as we approach the new season.”
Northamptonshire chairman Gavin Warren added: “We are very pleased to have Ray as our new CEO.
“He comes to the club with a wealth of experience in moving businesses forward and has a great commercial vision.
“Ray has been with us on the board for a number of months now, so he has seen how match days are run and how the club works as a business.”
