Scarlets have signed winger Michael Tagicakibau from Saracens.
The Fijian, who has five international caps, previously played for London Welsh and Bristol before moving to Sarries, for whom he played 52 times.
"He has great line-breaking ability but more importantly he's an excellent defender," Scarlets head coach Simon Easterby told the club’s website.
Easterby is excited by the potential in the back three next season, having also captured Wales wing Harry Robinson from Cardiff Blues.
"We have made it clear for some time that we are looking to strengthen our firepower out wide and with the addition of Michael, and Harry, we believe that we will have a very destructive back three in amongst a powerful backline," he said.
"Michael has international experience with Fiji and has experienced success with Sarries - we're looking forward to seeing him in action here at Parc y Scarlets and he will undoubtedly be a significant boost to the squad."
Tagicakibau said: "The region has some great players in the backline and I'm really excited about being a part of a club that has a strong ethos of running rugby.
“There's a young and talented group of guys there that have ensured qualification for the new Rugby Champions Cup for next season and I'm keen to make my mark and help the region with their continued success."
