Former England opener Marcus Trescothick has signed a new one-year deal with Somerset.
The 39-year-old has spent his entire career with his home county since making his first-class debut in 1993.
"Marcus is the absolute model professional," Somerset director of cricket Matthew Maynard told BBC Sport. "He has contributed a tremendous amount to this club.
"Whilst he is coming to the twilight of his career on the field his experience and knowledge are second to none and he still has a very important role to play both on and off the field."
Trescothick played 76 Tests, 123 one-day internationals and three Twenty20 matches for England.
