Al-Yamamah arms deal report comes to light ending anti-corruption campaigners’ battle

Inquiry by National Audit Office into British-Saudi arms contract reveals evidence of MoD deception over bribery allegations

A suppressed official report on alleged corruption in a giant British-Saudi arms contract has been discovered in a public archive, ending a three-decade battle by campaigners for the controversial document to be revealed.

The report, which the Guardian is publishing on its website along with various accompanying documents, is believed to be the only inquiry by Britain's public spending watchdog, the National Audit Office (NAO), to be so thoroughly censored, with only two MPs allowed to see its conclusions.
