The SNP is poised to take control of North Lanarkshire council for the first ever time, the Daily Record understands.
Labour councillors yesterday voted to be in opposition, effectively ensuring the SNP will lead the administration.
SNP councillor Jordan Linden is expected to be the next council leader, replacing Labour's Jim Logue.
North Lanarkshire was a Labour stronghold for many years and the party held on to the council in 2017 after suffering heavy losses across Scotland.
A tight result in May left no party in overall control, but the SNP came first with 36 councillors, four ahead of Labour.
Five Tories were elected, as well as one Green, two independents and a British Unionist Party representative.
Reports suggested Labour could secure the support of the other pro-UK councillors to form a minority administration, but their council group decided otherwise yesterday.
One Labour source said there had been an acceptance the SNP had won more seats.
An SNP insider said a change of administration would be a "totemic" moment and said a priority would be empowering communities.
The administration will be formed tomorrow.
Meanwhile, it has emerged that Labour has regained neighbouring South Lanarkshire council after losing control five years ago.
The SNP has run the council as a minority, but Labour's Joe Fagan will be the new leader.
