England spinner Graeme Swann has signed a new two-year contract with Nottinghamshire.
Swann, 33, is on an England and Wales Cricket Board central contract but the terms of his domestic deal, which runs until the end of the 2014 season, will come into force if that situation changes.
Swann said: "I'm wholly committed to England but if I'm ever dropped due to a lack of form then I will be back with Nottinghamshire."
He added: "When Mick Newell (director of cricket) signed me he told me that he wanted to win Championships and provide players for England and he has delivered on both fronts.
"I'm very proud of the achievements of the England team over the past few years because we have played some outstanding cricket and worked extremely hard to maintain our standards."
Newell added: "Graeme has excelled at the club and it was always evident that he had the potential to become a consistent international cricketer but he has surpassed everyone's expectations with his achievements since his Test debut."
Newell signed Swann in 2005 and Notts won the County Championship in his debut season at Trent Bridge.
