Spinner Monty Panesar has signed a three-year contract extension at Sussex.
The 29-year-old was the second-highest wicket-taker in Division One of the LV County Championship this year, behind only Worcestershire veteran Alan Richardson, and has taken 121 first-class wickets in two seasons since moving to Hove from Northamptonshire, adding 42 in limited-overs cricket.
He said: "I am delighted to have pledged my future to Sussex and I am equally pleased in the commitment that the club have shown to me.
"The club is going through an exciting period and I'm looking forward to helping them challenge for trophies. I aim to repay their faith by continuing my good form in all formats of the game whilst also improving my chances of reclaiming my place in the England side."
Sussex's professional cricket manager Mark Robinson said: "Monty is one of the best finger spinners in the world and we know how lucky we are to have him here at Hove".
