I thank my hon. Friend for giving way. He and I have sat through a number of meetings with groups from the Congo, Colombia and a number of other countries, where the most appalling damage has been suffered because of the irresponsible behaviour
of mining companies. Many of the mining companies claim in their defence that the actual mining work is done by some mysterious subsidiary—another supplier, another contractor—in order to evade their corporate responsibilities and the law of the country. Does he agree that we need to frame responsibility in law that guarantees the whole supply chain and not just the convenient end-part of it, where the large profits are made?
