Mining companies and other organisations submitting evidence to a UK parliamentary inquiry into the extractive industries have presented very different views on the regulatory regime for London-listed companies.

Hotline was intrigued to read the different views from mining companies and other organisations submitting evidence to a parliamentary inquiry into the extractive industries.

Various responses came in to the Business, Innovation and Skills Committee before this month's deadline for submissions.
