Broster joined Scarlets from Saracens in 2007 (Huw Evans)
Northampton Saints have signed Wales international prop Ben Broster as they continue recruiting for their return to the Guinness Premiership.
The 26-year-old tight-head joins from Llanelli Scarlets and will compete with Barry Stewart and Euan Murray in the front row at Franklin's Gardens.
Broster won two caps for Wales on the 2005 tour of North America.
Saints have also announced that veteran former Scotland and Lions prop Tom Smith has also signed a new deal.
It will be the 36-year-old's eighth season with the club after joining from Brive in 2001.
Broster said: "I'm looking to play and be part of a winning team, you can feel the buzz around the place."
The Saints won National One without losing last season and also lifted the EDF Energy Trophy at Twickenham.
The task is to get back into the swing of Premiership rugby and all that entails
Broster continued: "The boys have obviously had a terrific season. Confidence is high and it should lead well into the new season.
"The Premiership is always going to be a battle. This year it's been as close as it's ever been."
"The front row is an area of the squad where you cannot have too much depth," said Saints director of rugby Jim Mallinder.
"Ben and Tom both give us that. Tom's quality was apparent throughout last season; he had a fantastic campaign in the tight and the loose.
"Ben is an under-rated player who has proved his worth at the highest level. He is good in the tight, mobile around the park and also has international experience at all age groups."
