Aldi, the German discount food retail chain, is planning to invest around £50 mln (EUR 57 mln) in new stores across North and Mid Wales over the next five years. Local press has reported the company plans to open two stores next year and is also looking at sites for new stores in several towns. The company said the move was in response to a 30% increase in footfall in its stores in North Wales since the onset of the credit crunch.
