Celtic have equalled arch-rivals Glasgow Rangers' record of 55 Scottish Premiership titles after winning the trophy four rounds before the end of the season.
A 5-0 win over Dundee United gave the "Cloverleaf" an 18-point lead over second-placed Rangers, who have five games left.
It is Celtic's fourth consecutive league title. The team is aiming for a sixth domestic treble in the last nine seasons. The team has already won the Scottish League Cup and reached the Scottish FA Cup final against Aberdeen on May 24.
Rangers won the last of their 55 league titles in 2021.
Celtic won their 13th league title in the last 14 seasons. Brendan Rodgers' side have 84 points from 34 games and, despite Rangers having a game in hand, they can only collect a maximum of 81 points.
