Gullane have retained the East Lothian Winter League title after suffering just one defeat in the past two campaigns.
It came at the hands of Dunbar earlier this season, so it was fitting that a win over the same opposition clinched the crown again for Robert Jack’s side.
Having lost three times at home since December, Dunbar have now been plunged into a relegation dogfight. The Glen are already down and the clash between North Berwick and Dunbar on March 1 will determine the other side facing Division 2 action next season.
Musselburgh will secure second in the top flight if they avoid defeat at Royal Musselburgh.
Tantallon clinched the Division 2 title in style with a 5-0 win at Thorntree, though the decisive blow was delivered when Fraser Symon’s side won at Longniddry early last month.
Haddington had topped the table for much of the campaign only to suffer heartbreak for the second successive season by slipping out of the top two after losing 3-2 at Craigielaw.
Longniddry will go up with Tantallon after a 4.5-0.5 home win over Whitekirk secured second spot for Paul Gibson’s side.
Attention now turns to the Cup, with Tantallon travelling to Gifford in the remaining quarter-final. Tantallon will be hoping to secure a home tie in the last fourm but Gifford are fresh from rounding off their league campaign with a 5-0 win against Musselburgh Old.
