Bath have pulled off a major transfer coup with the signing of England centre Jonathan Joseph from London Irish.
Joseph, widely regarded as one of the brightest prospects in English rugby, will arrive at The Rec in the summer where he will be reunited with Toby Booth.
Booth left London Irish to join Bath's coaching team last year and he was pivotal in Joseph's development at the Madejski.
Joseph said: "I've loved my time with London Irish, but feel it's time to make a move and Bath is an extremely exciting prospect.
"You can see what the coaches are looking to build there in terms of culture, they already have a really talented squad and I hope I can add something to that. Obviously I'm still developing as a player and I feel that Bath will give me a fantastic environment in which to do that."
Bath head coach Gary Gold said: "Jonathan is young, English and hugely talented. He is exactly the sort of player we want, and we are confident that he will indeed bring something special to the team.
"That he has chosen Bath as his club says a huge amount about the environment we are establishing here. We can't wait for him to join the club."
The news of Joseph's departure is a major blow for London Irish, who have seen several of their big names depart in the last few years.
England prop Alex Corbisiero also leaving in the summer for Northampton and Steve Shingler is returning to the Scarlets.
