Luke Wright has signed a new three-year white-ball contract with Sussex, and will remain with the club until the end of 2023.
Sussex's white-ball captain has already spent 16 years at Hove, but reconfirmed his value to the club this summer, finishing as their leading run-scorer in the Vitality Blast, and the third-highest scorer in the entire competition, as Sussex reached the quarter-finals for the third time in as many years.
"I'm very happy to have signed an extension to my contract," Wright said. "I believe I have a very important role at the club both as a player and in helping the next generation of players come through.
"2020 has been a very challenging year for the club, and I sincerely hope to help get Sussex back to competing in all forms. This club is very special to me and my family."
Wright's tally of 411 runs during the 2020 Blast was only bettered by Kent's Daniel Bell-Drummond and Stevie Eskinazi of Middlesex, and his best performances came home and away against south-coast rivals, Hampshire.
He has scored a total of 7,998 runs in the Blast for Sussex, and a further 5,126 in List A cricket. He also played 101 times for England across ODI and T20 cricket, including a key role in the World T20 triumph in the Caribbean in 2010.
His highest England score was 99 not out against Afghanistan at the 2012 World T20 in Sri Lanka.
Performance director, Keith Greenfield said: "It's great that Luke has committed himself long term to Sussex Cricket.
"Luke is an outstanding batsman in one-day cricket and his experience and skill means he continues to go from strength to strength as a player.
"He is a valuable and important person within our club and his leadership to turn us into a winning team will be essential in the coming months and years."
