The Council has published a list of the outstanding amounts owed to it in each of the last 3 years.
The size of the debt shows an upward trend which could lead to cash flow problems if not reversed.
Although many of the debts will eventually be recovered, some will not.
There have been significant increases in the amounts owed on business rates, former tenant arrears and sundry debts.
In total the amounts owed have increased from £12 million to £16 million over a 3 year period.
