Brighton and Hove City Council has done a good job in enforcing parking regulations since it took over from the police last year.

Its parking attendants have been much more active than wardens in stopping the illegal parking that blocked busy roads and caused potential danger.

But that success has caused its own problems. There are always going to be people who don't fit easily into a parking system.

They range from builders carrying out work on houses to district nurses visiting patients at home.

Some allowances have to be made for them to get on with their work without abusing the system.

Many other councils have introduced fees for waivers - concessions which allow parking on yellow lines.

Now Brighton and Hove is thinking of doing the same and some traders have complained it would be unfair.

Yet the fee of £3 a day is not extortionate and if they move elsewhere, it may be to another city which does exactly the same thing.

The council may also introduce a traders' permit costing £300 a year for people such as plumbers and locksmiths who have to attend emergencies for short periods.

Councillors should approve the new fees for a short period to see if they work. If not, they can be dropped or amended.

That period should coincide with a much more wide-ranging review of parking controls, which should be finished by then.
