Leatherhead have been relegated to the Ryman League Division One South after losing 2-0 at home to Kingstonian today.
Other results went against them, with Hastings and Harrow Borough both winning, meaning the Tanners will return to Division One South after only one season in the Premier Division.
Bobby Traynor and Ryan Woods scored the goals that sealed Leatherhead's fate, but it does not tell the whole story with the home side missing a host of good chances to win the match and take the relegation battle down to the final day of the season.
Afterwards, chairman Peter Ashdown confirmed that manager Richard Brady would remain in charge next year, despite what he called a "disappointing" season.

Meanwhile in the Combined Counties League Premier Division, Dorking are not yet safe after they lost 5-0 at Molesey and the two teams also battling relegation, Chessington & Hook and Colliers Wood United, both won.
It means the Chicks are three points above the drop zone with one game to play, though Colliers Wood still have two to play.
