According to Gordon Bowden, at the Palestine Chronicle, 24 August 2010 (GlobalPost):
1. In 1991, Dr David Kelly oversaw the UK government's purchase of 3 battlefield plutonium bombs from South Africa.
David Cameron was sent by UK prime minister Thatcher to South Africa to seal the deal.
Reportedly the UK Treasury was overcharged by £17.8 million for the weapons. (Ex Dep. Asst. US Sec of State opens up a Pandora's Box.)
2. In 1991, in South Africa, Botha's white government was about to be handed over to the Black ANC.
The USA and UK asked Botha's Government to remove their 9 Bombs.
6 were to be sent to the USA for de-commissioning.
The other 3 were bought by the Thatcher government, for possible use against Saddam.
3. Reportedly, a Mr John Bredenkamp stole the 3 missiles.
He then sold them on the open market.
One of those stolen by Bredenkamp was detonated by NORTH KOREA on 25 May 2009.
