Council staff earning £100,000 or more is "particularly galling" given the cuts faced by many local authorities, the TaxPayers' Alliance have said.
Jonathan Isaby, chief executive of the Taxpayer's Alliance said:
Sadly, too many local authorities are still increasing the number of highly paid staff on their payroll.
It's particularly galling in places where councils are pleading poverty and demanding more and more in council tax.
Taxpayers expect their council to be filling potholes, not pay packets.
Many rank-and-file staff in local councils will be equally appalled - at a time when councils across the country are freezing pay, it appears the money they're saving is being used to line the pockets of town hall tycoons.
