Dan Kemp’s first goal for MK Dons set the hosts on their way to a 3-1 victory over nine-man AFC Wimbledon that lifted them up to sixth in League Two.
Three goals in the first 22 minutes were enough for MK Dons to see off their bitter rivals, who had Huseyin Biler and Paul Kalambayi sent off in the second half for professional fouls on Max Dean.
The hosts were ahead in the 10th minute when Joe Tomlinson got beyond Biler before his low ball allowed Kemp to tap in from close range.
Their lead was doubled in calamitous fashion six minutes later when Wimbledon centre-back Ryan Johnson sliced a hurried clearance over Alex Bass into his own net.
It got even worse for the visitors when an unmarked Warren O’Hora headed Ethan Robson’s cross into the bottom corner to score MK Dons’ third.
Armani Little pounced on a sloppy short goal kick to pull one back for Wimbledon eight minutes into the second half, but their comeback hopes were killed off by straight red cards to Biler and Kalambayi.
