Rangers moved four points clear at the top of the table with an impressive win over Dundee United in Walter Smith's last Ibrox game as manager.
Nikica Jelavic headed home from 15 yards after a Steven Whittaker cross on 21 minutes in a fine Rangers start.
Kyle Lafferty doubled the Gers lead soon after with a nice finish after coming close hitting the post earlier.
The Gers often cut United apart with some excellent football but were unable to capitalise.
The visitors pushed forward in the second half and kept the pressure on Rangers and came closest when they hit the post late on.
