New laws to tackle anti-social behaviour are expected in the Queen's Speech

The force was one of four areas across the UK to try out the programme, in which officers hand out fixed penalties - of between �40-80 - to offenders.

The scheme was brought in by Home Secretary David Blunkett in September last year, and could now roll out across the UK.

North Wales Police has declared itself pleased with the results of its pilot across Denbighshire and Conwy.

Twenty-four fines were given for public order offences and others were for being drunk and disorderly.

A spokeswoman said officers had also issued one fixed penalty for being drunk on a highway and one for purchasing alcohol for a minor.

There were no figures available to suggest how many people may have contested their fines.

Chief Inspector Mike Mullis said those people who had received on-the-spot fines for their behaviour had not committed a second offence.

"Officers are turning round to me and saying it will help them," said Ch Insp Mullis.

"Currently, our experience in north Wales is that persons fined do not go on to commit a second offence.

"It is a very quick, sharp method of giving a punishment for something minor without criminalising the offences."

"People have 21 days to pay a fine - we do not take any money off them at the time, there is a cooling-off period," he added.

Cracking down on anti-social behaviour - from noisy neighbours to street drunks - is one of the Government's main aims for the new parliamentary year.

New laws

The scheme was also tested in the west Midlands, Essex and the Croydon division of the Metropolitan Police.

Prime Minister Tony Blair is keen to expand the scheme, and it is expected to be one of the crime-busting tools mentioned in the Queen's speech on Wednesday.

New laws to tackle anti-social behaviour, ban most hunting with dogs, and reform the NHS are also expected to be unveiled.

The reform of the criminal justice system is also due to be announced.
