The 36-year-old Scot has made the decision after finishing 10th in the standings last year, his worst campaign since his maiden full BTCC season in 2018.
Butcher scored one race victory in 2023 with the Speedworks Motorsport-run Toyota Corolla squad to bring his total BTCC tally to 11 wins and has decided to return to his roots in sportscar racing this year by targeting the 24-hour races at the Nurburgring and Spa.
