Buckingham is a former partner of the
private military company Executive Outcomes. A top-secret British intelligence report stated that "Executive Outcomes was registered in the UK in September 1993 by Anthony (Tony) Buckingham, a British businessman and
Simon Mann, a former British officer". Buckingham denies that he registered Executive Outcomes in London and consistently denies any "corporate ties" to the defunct organisation. Tony, along with founder and CEO of Executive Outcomes, Eeben Barlow, Deputy CEO Lafras Luitingh, and Simon Mann were the
executive officers of
Ibis Air, a separate partner company that was the aircraft
procurement organisation that owned and operated many aircraft for EO and essentially operated as their private air force. Ibis Air could also access Soviet-era fighters and strike aircraft from the
Angolan Air Force. He has had no involvement with such organizations since 1999 and has spent his time running
Heritage Oil of which he is the founder and former
CEO. He was appointed to the
board of directors in early 2008, coinciding with the company's listing on the
London Stock Exchange. He was part of the
Valentine Strasser coup in Sierra Leone and was part of a group of mercenaries defending the National Provisional Ruling Council (NPRC), which later collapsed. To this day his name is still linked to these events and the fall of the government. == Oil background ==
