Celtic crowned Champions after win over Aberdeen.
Their triumph was already an inevitability, but the celebrations began in earnest as Patrick Roberts scored two fine early goals.
Aberdeen, who offered a stout challenge all season, looked dead and buried when Mikael Lustig scored after the break.
But quickfire goals from Niall McGinn and Andrew Considine took some of the gloss off the title party.
Celtic may have lost just three league games on their way to this latest triumph but manager Ronny Deila is departing in the summer.
The Norwegian cannot match the points tally from his debut season and this victory illustrated an inconsistency that has dogged his side throughout his second campaign.
The champions were irresistible in the first half but disjointed after the interval as Aberdeen ate into their lead.
