The multinational headquartered in London, along with the Nigerian government, has repeatedly stated that work to clean up oil-contaminated sites of Ogoniland, which kicked off around eight years ago, is going well.
But the news has discovered evidence that they were warned repeatedly over several years that the scheme, set up by the government and funded by various oil firms to the tune of $1bn (£805m), has been suffering from a string of issues.
One close observer has described the clean-up project as a “con” and a “scam” that has wasted money and left the people of Ogonliland, which lies in the Niger Delta.
