Striker Aaron Wilbraham bagged a brace as MK Dons sent Leeds crashing to a fifth successive defeat.
The hosts took the lead when Jemal Johnson's corner found Sean O'Hanlon and he headed into the Leeds net.
Their lead doubled when Wilbraham poked another Johnson corner in, before Leeds got back into the game when Robert Snodgrass volleyed in from 20 yards.
But the Dons wrapped things up when Leeds left Wilbraham unmarked for him to head in Johnson's cross.
Leeds United manager Gary McAllister told BBC Radio Leeds:
"I feel I am letting the fans down. The city of Leeds deserves better.
"We'll keep working, I'll continue to work hard with the players to put things right. That's my job."
