LAGOS (AFP) - A top official from oil giant Shell told the then-US ambassador in Abuja that the firm had access to everything that was being done in certain Nigerian ministries, a leaked diplomatic cable showed Thursday. The US diplomatic cable, published by British newspaper The Guardian and part of the huge trove of documents released by WikiLeaks, was dated October 20, 2009. It said Ann Pickard, then Shells executive vice president for sub-Saharan Africa, had met with the US ambassador at the time, Robin Renee Sanders, and discussed a range of issues. Pickard commented on Shells inside government information after discussing Chinas reported interest in Nigerian oil blocks, the cable said. She said the (government of Nigeria) had forgotten that Shell had seconded people to all the relevant ministries and that Shell consequently had access to everything that was being done in those ministries, the cable said. Shell is among the major oil producers in Nigeria, which is an OPEC member and one of the worlds largest oil exporters.
