The American pharmaceutical giant Pfizer has dismissed as preposterous reports that it hired investigators to uncover evidence of corruption against a former Nigerian attorney-general.
According to a secret US diplomatic cable cable released by WikiLeaks, Pfizer wanted to put pressure on Michael Aondoakaa because he was heading a lawsuit against the company over a 1996 drug trial during a meningitis epidemic.
The trial allegedly led to the deaths of 11 children and left dozens disabled - charges Pfizer denies.
Pfizer reached a $100 million settlement last year with Nigeria's Kano state government over the case.
