Paddy Jackson will join newly promoted London Irish next season.
The former Ulster out-half moves to the Madejski Stadium after a difficult period with Perpignan in the Top 14.
Jackson will link up with the former Ulster director of rugby Les Kiss and his old Ireland head coach Declan Kidney to play in the Gallagher Premiership.
The 27-year-old said today: "I’m delighted to be joining London Irish next season at such an exciting and pivotal time for everyone involved with the club.
"London Irish have a clear vision for where they want to be and I look forward to being part of it."
Declan Kidney added: "Players of the calibre of Paddy Jackson do not become available very often and both myself and Les are looking forward to working with him in the future.
"He is a player with proven international quality who we feel will add value to our squad, and it is pleasing that Paddy sees London Irish as a part of his future."
