Humble banger beats the downturn

Through the economic downturn, at least one product appears to have done well - the sausage.

In Britain, squeezed family budgets mean people have been trading down to cheaper cuts of meat, while rapid growth and higher incomes in emerging economies mean more meat-eating.

One company that is ambitious to cash in on that growth is a Lanarkshire maker of sausage skins and on Monday it will announce a big expansion.

The BBC's Scotland business editor, Douglas Fraser, speaks to Prof Mike Lean, a nutrition expert at Glasgow University, and Alan Kilpatrick, the managing director of the sausage skin factory.
