Options for raising more cash

The range of strategies for increasing parking fines, include:

? Simple increase by 50 per cent: the maximum parking ticket fines for central London would be increased from £80 to £120 - with a 50 per cent reduction to £60 for payment within 14 days. Fines for Band B would cost a maximum of £80, reduced to £60 in Band C.

? Creating a sliding scale of penalties. These would range from the most serious - to be known as "prohibited" parking - which would include parking on yellow lines. They would bring fines of as much as £120.

Less serious offences, such as overstaying at meters, would be charged at up to £100.

? Reducing the discount rate for prompt payment. The ALB suggest changing the 50 per cent reduction for payment within 14 days to either 25 per cent or 40 per cent.

? Increasing the cost of being clamped "in line with inflation". Drivers would have to pay £50 for their car to be freed from a clamp, up from £45. Release from a car pound would rise from £125 to £136. Car pounds would charge £16 storage per day, £1 more than the present rate.
