Scott Borthwick will join Surrey at the end of the season having rejected a contract extension from current club Durham.
Borthwick, 26, has agreed a three-year contract at the Oval having made one Test appearance for England when he faced Australia in 2014.
The all-rounder has also played two ODIs in 2011, making one T20 appearance in the same year.
He made his Durham debut in 2009 and a Durham statement said: “The club made a strong offer to keep his services but he has decided to accept an offer elsewhere.
“We respect his decision. Scott has been a good servant of the club and we would like to take this opportunity to wish him well for the future.”
