Ian Salisbury has left his position as Sussex head coach.
He spent the best part of two years in the role, taking responsibility for the club's LV= Insurance County Championship and Royal London Cup sides.
Earlier this week, BBC sport reported Salisbury had been placed on leave following a "non-cricketing disagreement" with spinner Jack Carson.

Carson, 21, spent a large chunk of the season on the sidelines with a knee injury but did feature in Sussex's final three County Championship outings of the season.
Commenting on his exit from the club, Salisbury said: "I've really enjoyed my time at Sussex for last two years and the journey has really helped me after the loss of my wife. However, it's the right thing for myself and daughter to look for a fresh challenge.
"I want to thank the backroom staff, ground staff, foundation, office staff, catering and stewards for their support throughout my time at Hove. Whoever takes over from myself will inherit a very talented homegrown squad who if supported from above are ready to fly in next few years."
Chief executive, Rob Andrew, added: "We would like to thank Ian for his contribution to the club over the last couple of years and wish him well for the future in whatever this may hold.
"He has helped develop a very promising group of young players and we are looking forward to seeing them develop further in the next few years."
