Celtic look on course for the biggest ever winning margin in the top flight of Scottish football following a thrilling 5-2 win over Aberdeen that moves them a massive 30 points clear of the Dons in second place.
Scott Brown and Kris Commons both scored a double as the Hoops gained revenge on Aberdeen, who inflicted their only league defeat of the season back in March.
Celtic skipper Brown opened the scoring in the 25th minute before Niall McGinn capitalised on a defensive mistake to level the scores three minutes later.
Brown restored the lead just before the break and Anthony Stokes added a third in the 53rd minute.
A tremendous strike from Shaleum Logan reduced the deficit three minutes later but a Commons double put Celtic out of sight.
Despite the defeat Aberdeen have booked their place in the Europa League qualifiers although Motherwell moved to within a point of the Dons with a 2-1 win over St Johnstone.
Dundee were promoted to the Scottish Premiership with a 2-1 win over Dumbarton that sealed the Championship title despite second-placed Hamilton breathing down their neck with a 10-2 win over Morton.
