Group leaders at Aberdeen City Council are to meet top officials of umbrella council body Cosla on August 22 – the day before the council will decide whether to re-join.
The meeting was arranged following the decision of the Tory-led administration on Aberdeen City Council to reject rejoining the organisation in May.
All former members of the Scottish Local Government Partnership (SLGP), except Aberdeen, have re-joined the organisation.
The previous Labour-led administration left the group, which negotiates funding settlements between the Scottish Government and the majority of other councils, to form the Scottish Local Government Partnership, two years ago.
The SNP local government manifesto included a commitment to re-join the organisation.
SNP group leader Stephen Flynn, said:“We have long argued that the council should be a member of Cosla and, quite frankly, it’s embarrassing that we are now the only local authority without representation.
“The Tories were either unprepared or too afraid to take the decision to re-join CoSLA in May and that decision ultimately cost Aberdeen the opportunity to put forward candidates for the key roles in the organisation.”
But Conservative group leader, and council finance convener Douglas Lumsden, said: “The unforgivable thing here is the unquestioning subservience of SNP councillors to their masters in Edinburgh, who time after time fail to stand up for Aberdeen.
“In May, we asked officers to assess any penalties that would be applied before rushing back into Cosla. I look forward to the meeting.”
