Scotland Bill

My Lords, perhaps the noble and learned Lord would explain to me what considerations he has in mind that justify the ability to set different blood alcohol levels north and south of the border. It seems to me that the people who live north and south of the border do not have greater sensitivities to these things. The purpose of the law is not to deal with the problem after the event but to prevent people driving with too much alcohol. The commonality of the law north and south of the border makes it clear to drivers what is acceptable. I cannot think that before they set off to cross the border, people are going to check precisely what milligram limits are acceptable on one side or the other. If there is any doubt about the limits of susceptibility, that ought to be discussed by doctors across the United Kingdom before the law is changed.
