The legal age at which you can smoke in North Britain is to change to 18 in an attempt to make the country more healthy. Smoking is already banned in all public places.
The full ban in England was diluted by an MP elected in North Britain and then voted on and passed by MP’s elected in all four home nations despite only having effect in England. Any attempt to raise the age limit in England would, of course, be scuppered by MP’s who have no business getting involved in English legislation.
As DK points out, Labour has an interest in making sure the tobacco companies keep turning huge profits – the North British Executive’s pension scheme has invested heavily in the tobacco industry.
