Brighton
took advantage of a first-half capitulation by Leeds United at the Amex
Stadium to move just two points behind Championship leaders Burnley.
Tomer Hemed opened the scoring with a chipped penalty, the hosts' first goal of four inside the first 38 minutes.An unfortunate own goal from Liam Cooper doubled Brighton's lead, before Hemed slotted in his second and Lewis Dunk headed in from a corner.
The defeat was Leeds' heaviest since Steve Evans took charge in October.
