Britain's Supreme Court has given the go-ahead for the introduction of minimum unit pricing for alcohol in Scotland — a watershed moment for public health advocates alarmed at the level of abuse.

The court on Wednesday rejected the Scottish Whisky Association's challenge to the policy of setting a floor price per unit of alcohol. Health advocates argue that the increasing affordability of alcohol is leading to an increase in consumption.

Scotland's First Minister Nicola Sturgeon tweeted on Wednesday that she was "absolutely delighted" by the decision that she says will prove to be a "bold and necessary move to improve public health."

During the 1980s alcohol deaths in Scotland had been relatively stable, at roughly 600 per year, but in 2006 drink-related deaths peaked at 1,546.
