Mark Davis named Sussex head coach
Davis, 44, was an offspinner and made his Sussex debut in 2001, having previously played first-class cricket in South Africa where he was born, and he was appointed Sussex 2nd XI coach in 2005.
He will form a new coach-captain pairing with Luke Wright who was appointed club captain in place of Ed Joyce following the 2015 season where Sussex were relegated from Division One in the County Championship.
"I'm very excited and honoured to be taking over as the new head coach at Sussex, and continuing the work that Peter Moores initially began, and that Mark Robinson continued so brilliantly. I'd like to thank Mark for everything and wish him well for his future role," Davis said.
"We will be working hard to continue with the values that Sussex stands for and to ensure that the county competes at the forefront of English cricket. We have a fantastic squad which has a good mix of youth and experience and we have some exciting challenges ahead. I am looking forward to working alongside our new captain Luke Wright."
Sussex's chief executive Zac Toumazi said: "Today's news has mixed emotions for us as a club. We are sorry to see Mark Robinson leave us as he has been a loyal servant to Sussex cricket. I am sure he will be a fantastic asset at the ECB.
"Following an ongoing review of our professional cricket structure, we are delighted to announce that Mark Davis will assume the role of head coach. This is a fantastic opportunity for Mark and chance for him to work closely with our newly-appointed captain Luke Wright."
