Leinster Rugby CEO Mick Dawson will step down from his position at the end of the current season after over 20 years in charge.
Dawson has been at the helm since November 2001 and has overseen a period of unprecedented success on and off the field for the province.
"It's been a difficult decision but after 20-plus years I think the time is right," said Dawson.
"I’ve enjoyed every minute of it, and I’d like to thank all the great people I’ve worked with over the years. Volunteers, administrators, staff, coaches and players.
"None of what Leinster Rugby has achieved would have been possible without the support, counsel and friendship of a huge coterie of highly talented and committed people.
"Over the years I’ve always enjoyed a great working relationship with the IRFU, our sponsors and supporters, a big thank you to one and all."
IRFU CEO Kevin Potts commented: "I want to thank Mick Dawson on behalf of everyone in the IRFU.
"For more than two decades, Mick has led Leinster with passion and distinction. There is no doubt that as CEO he created a winning culture, committed the resources and provided the guidance that has helped to shape sustained success on and off the pitch for Leinster.
"Mick has been a fantastic colleague to work with, always willing to challenge and always in the best interests of rugby, especially his beloved Leinster.
"I wish Mick and his family well in the future, he has left the Leinster jersey and the game in a better place than he found it, and that is a job well done."
The IRFU has appointed international recruitment consultancy Korn Ferry to assist them with the process of appointing Dawson's successor.
