Former Labour councillors in Aberdeen have been given no indication how long the investigation into their suspension from the party will take.
All nine members of the Labour group in Aberdeen were suspended in May for breaching party rules after they formed a coalition with Conservatives in the city.
The move came after the council elections at which Labour lost eight seats and became the local authority’s third largest party.
To get back into power the group had to do a deal with the Tories, in defiance of the Scottish Executive Committee of the Scottish Labour Party.
Councillors in the city are still no wiser about the investigation.
Councillor Ross Grant, who represents Tillydrone, Seaton and Old Aberdeen, said: “We have had no contact with the Scottish Labour Party about the investigation.
“At the moment I am getting on with being a councillor and serving the people in the Tillydrone, Seaton and Old Aberdeen who elected me to do so.
“Clearly, being suspended was something we didn’t want to happen, however, we will await the outcome and take it from there.”
The night before the full council meeting on May 17 at the Town House, the Scottish party’s executive committee warned the group again about doing a deal, but they still went ahead.
All Labour councillors were requested to stand down from the coalition arrangement – which included independent councillors – by 5pm that same day.
The deadline passed and the party contacted each councillor to inform them of their suspension with immediate effect, pending investigation.
The Scottish Labour Party has confirmed there are currently no Labour councillors in Aberdeen and refused to say when the investigation would conclude.
A spokesman for the party said: “There is an ongoing investigation. The Labour party does not comment on ongoing internal investigations.”
