Pembrokeshire has had one of Wales' highest percentages of festive season drink-drivers with over 7% of 440 motorists breathalysed being over the legal limit.

That means one in 14 Pembrokeshire drivers was unfit to be behind the wheel, compared with the overall Dyfed-Powys force figure of one in 20.

Thirty one of them had drunk too much alcohol, while two were under the influence of drugs.

Nearly 40% were under the age of 25, while 13% gave positive breath tests after road accidents. A number have appeared before courts to receive driving bans of 12 months and upwards.

While the local knowledge of Pembrokeshire police officers in targeting drink-drive suspects may have contributed to the higher figure, senior police say it is still a matter of concern.

Superintendant Euros Lewis said: "It is disappointing that the figures are higher than last year, particularly in the younger age group.

"Our efforts to reduce the number of drink-drivers will continue during 2006 through enforcement and education."

The Christmas drink-drive campaign, Operation Sherry, was operated by the four Welsh police forces throughout December and up to January 2nd.

It resulted in 11,550 breath tests, with 638 - around 5.5% - being positive.

In Dyfed-Powys, 2,159 drivers were tested with 106 - nearly 5% - being over the legal limit.

Added Superintendant Lewis, who is in charge of police operations in Pembrokeshire: "The fact the campaign has now ended does not mean we will be paying less attention to the problem. Any alcohol will have an effect on driving ability. Before anyone even considers drinking and driving, they should think carefully of the potential devastating consequences of their actions."
