A total of 149 people have been charged with drink and drug driving following this year's Christmas crackdown by police.
The last four people arrested over the December operation were charged this week, bringing the total number to 149 out of 209 arrests.

This year 104 have pleaded guilty so far and been dealt with by the courts while 45 are going through the legal system.

Superintendent Jane Derrick said: "In one respect it is disappointing that the number of people who were arrested went up, as it confirms that drink and drug driving remains a problem in Sussex.
"At the same time, it shows that we are determined to tackle the problem and that we will continue to make arrests and prosecute those whose selfish behaviour makes the roads more dangerous.
"It should be remembered that drink driving is not just a problem in Sussex at Christmas and officers are out on patrol looking for offenders 24 hours a day, 365 days a year.”
