Super League referee Thierry Alibert has left his role to take up a position as head of match officials with the French Rugby League Federation, the Rugby Football League has confirmed.
The 42-year-old returns to his home country after a lengthy stint in England, with his first Super League assignment coming in June 2008.
Alibert has also officiated at the 2000, 2008 and 2013 World Cups.
"I would to thank everybody at the RFL who has supported me during the last five years," he said.
"After the World Cup in 2008, the day when my mobile phone rang and Stuart Cummings asked me to come and referee in Super League was a great day in my career.
"I will never forget the opportunities I have had, or the great people I have met. In the last few months it has been a little hard for me, so when the opportunity with the FFR13 came I didn't hesitate."
