A BBC Scotland investigation into Buckfast Tonic Wine has uncovered new evidence about links between the drink and violence.
It has led to calls for the monks who produce Buckfast to make it available in plastic bottles rather than glass.

This investigation had no agenda.
Rather than start from the standpoint that this humble tonic wine was a "bad thing", we simply wanted to find out why it had acquired a reputation, particularly in the central belt, as Scotland's "commotion lotion".
What became clear was that Buckfast is a cultural phenomenon with an impact far greater than its tiny share of the Scottish drinks market would suggest.
We asked Strathclyde Police about the drink using the Freedom Of Information Act.
They told us that Buckfast was mentioned in more than 5,000 crime reports over the last three years.
That works out as an average of about three offences a day.
More worryingly one in 10 of those offences was a violent one.
