People who download music illegally also spend an average of £77 a year buying it legitimately, a survey has found.

"The scale of unlawful file-sharing poses a real threat to the long-term sustainability of our creative industries," said a spokesman for the Department for Business, Innovation and Skills.

"While surveys asking people about unlawful behaviour should be treated with caution, it's encouraging that the findings signal that the three-pronged approach set out by the Government this week - a mix of education, enforcement and attractive new commercial deals - provides the best way forward for industry and consumers."
