The 26 year-old has made 98 appearances for Bath and scored 15 tries since he joined the Club in the 2005/06 season. But, with a back row bolstered by significant new summer signings, Chief Executive Nick Blofeld believes that Jonny will be able to fulfil his hopes of more game time at the Welsh club.

"Jonny and his agent said to us that he was looking for more guaranteed game time and we believe that this opportunity will be able to offer him just that.

"He has been a fantastic addition to Bath Rugby and has played with real flair during the five seasons with us. He has also been a real crowd favourite and a popular character around the city. With our new recruits though, we are confident that this is a good move for Jonny and that the Scarlets and he will benefit from the additional game time that this will give him."
