Big Food Group, the parent of UK high street food retailer Iceland, has reported a disappointing set of quarterly sales figures. The 760-strong Iceland chain reported sales down 7.7% in the 13 weeks to the end of September, prompting the group's share price to fall to a record low of £0.25 (US$0.39). This is a further blow to investors who saw shares rise to £3.40 just two years ago.
