Leeds threatened from the outset and the Whites finally went ahead in the 58th minute as Georginio Rutter tapped home from close range after a brilliant Sam Byram header from a Dan James corner had been saved.
More chances then came United’s way but Daniel Farke’s side were then saved by an outstanding save from keeper Illan Meslier to keep out a Kiernan Dewsbury-Hall header with 95 minutes on the clock.
Leicester could have gone 17 points clear of third-placed Leeds with a victory but the Whites instead cut the gap to 11 points as they also moved to within six points of second-placed Ipswich Town in the automatic promotion spots.
Graham Smyth, the YEP’s chief football writer, hands out the scores from a brilliant night for Farke’s side at the King Power.
