According to the council accounts Highways and parking reserves (cash held in the bank by the council) increased from 1 April 2021 to 31 March 2022 by £5,846,000 from £1,852,000.
That means that this time last year they were sitting on £7,698,000 of our money.
But it seems that just isn't enough money for them and now they are taking more from you if need to use your own car.
