Eight Scottish councils have been discussing plans for a massive shared services venture.
Glasgow City Council confirmed that leader Steven Purcell (Lab) was holding talks with seven authorities about sharing a range of services including council tax collection, housing benefits and IT.
A Glasgow spokeswoman said negotiations had begun with East and West Dunbartonshire , East Renfrewshire , Renfrewshire , Inverclyde and North and South Lanarkshire councils about the proposals.
Cllr Purcell said: “There will be no no-go areas. We’ve got a blank sheet of paper.
"We don’t believe political boundaries need to change and are very conscious of the importance of local identity. What really matters is accountability.”
The group of Clyde valley councils represents a quarter of Scotland’s local authorities which together face a funding deficit and need to make£500m of savings in the next few years.
