Torquay dropped to the foot of League Two as they slumped against MK Dons.
The Gulls missed several chances before Clive Platt put the Dons ahead when he lashed the ball into the top corner.
Izale McLeod, who has been linked with a big move in January, made it 2-0 from the penalty spot on 38 minutes, having been fouled himself by Steve Angus.
With eight minutes left Torquay boss Lubos Kubik took the unusual step of taking off Nathan Abbey and replacing him with reserve keeper Martin Horsell.
